SUMMARY SHEETS 

Paradox V~lley Unit 

Colorado River Basin Salinity Control Project 

LOCATION 

The Paradox Valley Unit would be located in Montrose and San Miguel 

Counties of southwestern Colorado in the Upper Colorado River Basin. 

PLAN 

The unit would be designed to reduce the salinity of the Dolores and 

Colorado Rivers by. pumping brine ground water from a well field located 

along the Dolores River in Paradox Valley and thus preventing it from 

surfacing in the riverbed. A test well field has already been installed 

as part of a design data collection program, and other facilities required for brine treatment and disposal would be added during unit 

construction. 

The brine would be piped from the well field to a nearby hydrogen sulfide stripping plant, where potentially toxic and corrosive gas would be 

converted into sulfur. An operational headquarters would be constructed 

at the site of the stripping plant. The treated brine and sulfur would 

be piped from the stripping plant to the proposed Radium Evaporation 

Pond for disposal. The pond·would be located in Dry Creek Basin to the 

southeast of the w~~l field, and eight pumping plants would be installed 

on the pipeline to lift the brine over the divide between Paradox Valley 

· and the bas in. 

To reduce adverse impacts on wildlife, a wildlife area would be developed near the evaporation pond and other areas temporarily disturbed by 

construction would be seeded with plant species valuable as wildlife 

habitat. Since the wildlife area was not included in the unit plan 

when it was authorized, the approval of the appropriate congressional 

committees would be required. Also included as part of the unit would 

be a cultural resource program to collect and preserve archaeological 

information from two sites located within the proposed evaporation pond.

CHAPTER I 

INTRODUCTION 

Unit Purpose and Location 

The hydrosalinity appendix presents the results of definite plan studies of the Paradox Valley Unit, Colorado, of the Colorado River Basin Salinity Control Projects. The unit, as shown in Figure 1 on the following 

page, is one of four salinity control units authorized for construction 

by Title II of Public Law 93-320 signed by the President on June 24, 1974. 

The three other units are the Grand Valley Unit, Colorado; the Las Vegas 

Wash Unit, Nevada; and the Crystal Geyser Unit, Utah. Prior salinity control investigations were authorized by the Colorado River Storage Project 

Act (Public Law 84-485), the San Juan-Chama Project and Navajo Indian Irrigation Project Act (Public Law 87-483), and the Fryingpan-Arkansas Project Act (Public Law 87-590). 

The Paradox Valley Unit would be located in Montrose and San Miguel 

Counties of southwestern Colorado, just east of the Colorado-Utah State 

line as shown on the frontispiece map. The unit area would consist of 

Paradox Valley on the main stem of the Dolores River and the northwestern 

part of Dry Creek Basin to the southeast in the San Miguel River drainage. 

The San Miguel River is a tributary of the Dolores River, which in turn 

is a tributary of the Colorado River. 

The Paradox Valley Unit would be designed to reduce the brine inflow 

to the Dolores River in Paradox Valley. This inflow has been identified 

as a major natural point source of salt in the Upper Colorado River Basin. 

As the river crosses the valley it picks up an estimated 205,000 tons of 

salt annually from surfacing brine ground water and irrigation return 

flows and carries them to the Colorado River. 

Unit Setting 

Economic development 

The only communities in Paradox Valley are the very small farming 

towns of Paradox and Bedrock. Other communities in the vicinity are 

Nucla, Uravan, and Naturita, all located on, or near, the San Miguel River 

to the east of the valley. There is no permanent population in the northwestern part of Dry Creek Basin. 

Paradox Valley was first settled in 1877 by farmers and ranchers. Although sporadic mining booms have occurred since that time, agriculture 

and some small industries have remained as the economic base for the 

people in the valley.

CHAPTER I IN'l'RODUCTION 

Agriculture in Paradox Valley is confined to the West Paradox Creek 

watershed which contains about 60~300 acres, with approximately half in 

private ownership and the remainder under Federal control.. The watershed 

is located in portions of Montrose County, Colorado, and San Juan and 

Grand Counties, Utah~ About 2,500 acres are under irrigation with a water supply from West Paradox Creek, Buckeye Reservoir in the La Sal Mountains to the northwest, and ground water wells. Livestock and livestock 

feeds provide the principal source of income, The eastern half of the 

valley provides a limited amount of range, and Dry Creek Basin also provides some sparse grazing. 

Two sawmills located near the town of Paradox process timber from 

the La Sal Mountains to the northwest and the Uncompahgre Plateau to the 

east, but these operations provide little employment. Mining also contributes to the local economy. Carnotite, a mineral containing the radioactive elements uranium, vanadium, and radium, is mined on the mesas surrounding Paradox Valley. This activity has increased considerably in recent years. A major portion of the ore is shipped to a processing plant 

in Uravan, which uses brine from a well in Paradox Valley in the milling 

process. Brine from a second well is sold for use in drilling operations 

in the area . 

Vegetation 

Natural vegetation in the project area varies according to elevation, 

precipitation, soil, and other factors. The Dolores River supports riparian vegetation characterized by cottonwood and forestiera upstream from 

the brine seeps and tamarisk downstream, with forbs and grasses found in 

both sections. Rushes are found in marshy areas along the stream. In· 

both Paradox Valley and Dry Creek Basin, extensive semiarid areas with 

saline soils are characterized by greasewood, seablite, winterfat, snakeweed, and other salt-tolerant plants. Sagebrush is found on higher slopes 

throughout the area and is associated with a large variety of grasses wherever overgrazing has not occurred. Pinyon-juniper woodlands characterize 

the mesas and high slopes. No endangered or threatened plants have been 

identified in the unit area. 

Fish and wildlife 

In the vicinity of Paradox Valley the Dolores River and West Paradox 

Creek support primarily nongame fishes, including the speckled dace, flannelmouth sucker, roundtail chub, mottled sculpin, red shiner, bluehead 

sucker, fathead minnow, black bullhead, and channel catfish. Because of 

the influx of saline ground water in the valley, fish inhabit the reach 

in and immediately downstream only when the streamflow is high enough to 

dilute the salt and move into other reaches or tributaries whenever low 

flows result in high salinity .

CHAPTER I INTRODUCTION 

Big game mammals in the unit area include the mule deer, elk, pronghorn, black bear, and mountain lion. Small game mammals, furbearers, varmints, and nongame mannnals are found throughout the vicinit;:y of the unit. 

Over a hundred species of birds, including both resident and migrant populations, have been identified in the area. 

The peregrine falcon is the only threatened or endangered species 

known· to inhabit the unit area, A mating couple nested and produced one 

offspring during the spring of 1977. 

Climate 

The climate in the project area is characteristic of the semiarid 

southwestern United States, with low precipit-ation and humidity, abundant 

sunshine, high evaporation rates, and wide ranges between daily high and 

low temperatures. The prevailing winds are from the southwest and are 

fairly strong in the spring with some winds year round. 

The Bureau of Reclamation has maintained weather stations at Bedrock 

in Paradox Valley and in Dry Creek Basin since February 1975. During that 

time, the average annual precipitation has averaged about 8 inches at both 

stations. June is usually the driest month of the year, and July through 

October are the wettest, primarily because of afternoon showers which occasionally reach thunderstorm intensity. A small to moderate amount of 

snow falls during the winter. Maximum and minimum temperatures for the 

years 1975 and 1976 have been 103° F and -22° F for the Bedrock station 

and 92° F and -26° F for the Dry Creek Basin station. 

Topography and geology 

The unit area is located in a region topographically characterized 

by narrow mesas, broad plateaus, long narrow valleys bordered by steep 

cliffs, and deeply entrenched canyons and gorges. The most prominent 

geologic features in the vicinity of the unit are the La Sal Mountains, 

rising to elevations of over 12,000 feet to the northwest, and the Uncompahgre Plateau, a broad uplift of between 8,500 and 10,000 feet in elevation to the northeast. As the Dolores River enters Paradox Valley, it 

emerges from a 50-mile stretch of narrow and deep canyons which twist 

through high mesas. 

Paradox Valley is one of five major collapsed salt anticlines in 

southwestern Colorado and southeastern Utah as shown on Figure 2 on the 

following page. A northwest-southeast trending, elongated valley about 

24 miles long and from 3 to 5 miles wide has been formed by the erosion 

of faulted and uplifted sandstone and shale formations. This process 

has exposed a residual gypsum cap which covers up to 14,000 feet of relatively pure salt and salt-rich shale. The process is illustrated in Figures 3 and 4 on pages 6 and 7. The emergence of mountainous uplifts on

CHAPTER I INTRODUCTlON 

each side of the area has placed intense lateral pressures on the intervening sedimentary formations, resulting in faulting and fracturing along 

weak axial zones. With the relaxing of the lateral stresses combined 

with the weight of the overlying strata, a deeply buried layer of saltrich material has flowed upward into the faulted area to create an anticline. The Dolores River has remained in its original streambed during 

this time and, in combination with other erosional forces, has removed 

the collapsing upper materials to form the valley. Contributing to the 

collapse have been the constant dissolution and removal of the underlying 

salt bed by ground water. These processes, which began 200 million years 

ago, are still active. 

The floor of the valley is relatively flat and smooth, sloping gradually from both ends toward the Dolores River. In the southeastern half, 

the surface is broken by low outcrops of gypsum. The surrounding walls 

are nearly vertical and in some places rise nearly 1,500 feet above the 

floor, exposing brilliantly colored strata of sandstone and shale. Landslide materials and talus slopes are common along the bases of slopes. 

The Dolores River enters Paradox Valley at about the valley midpoint and 

crosses perpendicular to the valley's axis. Because of the very low 

slope in the riverbed, velocities of the river through the valley are 

very slow and extensive flood plains have been created on both sides of 

the river. Two areas of brine inflow have been identified in the river 

channel and are shown on the first photograph on the following page. 

Dry Creek Basin, southeast of Paradox Valley, is separated from the 

valley by high mesas which have developed from the uplifted sedimentary 

flanks of the salt anticline. The West Fork of Dry Creek lies in a shallow structural syncline, or natural basin, with gently rising slopes. 

An artist's concept of Radium Dqm and Evaporation Pond in Dry Creek Basin 

is shown in the second photogra~h on the following page. Mancos Shale, a 

brackish and impervious marine f-ormation, underlies most of the basin and 

is frequently found in remnant form on the surface. The bedrock formation, consisting of Dakota Sandstone, is exposed along the north edge of 

the basin and dips sharply toward the center, disappearing under the Mancos Shale. The area is topographically breached on the north side, where 

the West Fork flows through to join Dry Creek. 

Water resources 

The major streams in the project area are the Dolores River and its 

largest tributary, the San Miguel River. Smaller tributaries of the Dolores include La Sal Creek, which enters from the northwest about 5 miles 

upstream from Paradox Valley, and West Paradox Creek, which enters from 

the northwest within the valley, East Paradox Creek enters the river 

from the eastern part of the valley and is intermittent, having essentially no effect on riverflow. Dry Creek, which drains all of Radium 

Evaporation Pond site, is a tributary of the San Miguel River, The Dolores and San Miguel Rivers exhibit the large fluctuations characteristic

CHAPTER I INTRODUCTION 

of streams in southwestern Colorado, with very high runoff during the 

spring because of melting snow in the mountains and very low flows after 

midsummer. High flows occur in the summer and fall from afternoon thunderstorms but are of very short duration. 

The Dolores River is relatively fresh as it enters the valley and 

saline as it leaves, especially during low flows. The flow-weighted average salinity nearly triples as the river crosses the valley because of 

emerging brine in the river bottom~ This is the major water quality problem in the project area. The brine inflow areas along the river are shown 

in the first photograph on the preceding page. 

Both sides of the Dolores River are underlain by nearly saturated 

brine with a total dissolved solids concentration of about 260,000 milligrams per liter (mg/1), containing approximately 87,400 mg/1 sodium and 

143,400 mg/1 chloride. This brine ground water comes from the underlying 

formation of salt and salt-rich shale and discharges through seeps and 

springs at several points in the two brine inflow areas. Brine inflow 

rates are estimated to range from 0.2 to 2.1 cubic feet per second (cfs). 

The west portion of the valley has a relatively fresh ground water zone 

(1,500 mg/1) on top of the brine, whereas little fresh ground water is 

found in the east portion • 

Unit Description 

Plan of development 

The annual inflow of salt into the Dolores River would be reduced by 

about 180,000 tons, or about 90 percent, by drilling 18 wells into the 

brine aquifer on both sides of the river and pumping brine from the wells 

at a rate sufficient to control the natural discharge into the river. 

This would lower the potentiometric head and the freshwater-brine interface, which would proportionately reduce the brine inflow. As part of a 

design data collection program, these wells are presently being drilled 

and tested. 

The brine would be pumped from the wells and discharged into a pipe 

manifold system to a Hydrogen Sulfide Stripping Plant .. which would remove the hydrogen sulfide gas that is present in the brine. This gas 

would have to be separated from the brine because of its toxicity, corrosiveness, and obnoxious odor. In the stripping plant the hydrogen sulfide 

gas would be converted to elemental sulfur and water through an air oxidation process. 

A buried pipeline would convey the brine and elemental sulfur from 

the Hydrogen Sulfide Stripping Plant to the Radium Evaporation Pond. The 

pipeline would be 20.5 miles long, extending to the southeast along State 

Hi.ghway 90, then crossing the divide between Paradox Valley and Dry Creek

CHAPTER I INTRODUCTION 

Basin, and terminating at Radium Evaporation Pond. Eight relift pumping 

plants would be required to achieve the total lift of about 2,040 feet 

between the well field and the top of the divide, with the first pumping 

plant located adjacent to the Hydrogen Sulfide Stripping Plant. 

Radium Evaporation Pond would be formed by the construction of a dam 

on an intermittent tributary of the West Fork of Dry Creek and a dike on 

an intermittent tributary of the East Fork~ All brine and natural inflow 

would be stored and evaporated at this facility. 

For the Definite Plan Report and the Environmental Impact Statement 

all facilities are designed on the extreme condition that 5 cfs of brine 

with a salinity of 260,000 mg/1 must be pumped constantly during the 100-

year life of the unit to control the salt pickup by the Dolores River. 

The design data collection program, which is presently being carried out 

and is scheduled for completion by the end of fiscal year 1979, will be 

used to test and make modifications to the well field and to determine a 

final design capacity for the Hydrogen Sulfide Stripping ~lant, the brine 

pipeline and pumping plants, and the evaporation pond. 

Unit effects 

Under the extreme condition that 5 cfs would have to be pumped constantly from the well field, ·the unit would cause a depletion of about 

3,600 acre-feet annually from the Dolores River or a little more than 1 

percent of the average annual flow. It is more likely, however, that a 

lesser pumping rate will be sufficient and the unit depletion should be 

considerably less. The average annual runoff in the two intermittent 

tributaries to Dry Creek of about 350 acre-feet would be stored and evaporated in Radium Evaporation Pond. The maximum average annual depletion 

from the Colorado River attributable to the Paradox Valley Unit would be 

about 3,950 acre-feet, 

The Bureau of Reclamation estimates that the brine well field would 

effectively remove up to 180,000 tons of salt annually, or about 90 percent of the salt now entering the river. The overall effect of the unit 

would be to decrease the salinity of the Colorado River at Imperial Dam 

by 18.2 mg/1, or about 1.6 percent of the salinity level under 1976 modified conditions.l/ The reduction attributable to salt removal would actually be 18.6 mg/1 but would be slightly offset by an increase of 0.4 

mg/1 caused by an average annual stream depletion of about 3,950 acrefeet. The unit effects on salinity are developed in more detail at the 

end of Chapter III.

nearing construction (final EIS filed) as being completed.

CHAPTER I INTRODUCTION 

Unit Investigations 

Much of the geologic and ground water in£o~mation p~ey~ously discussed was obtained through a ser~es of drilling programs and pump tests. 

Feasibility investigations were initiated in 1971 to study control methods 

to prevent the salt from entering the Dolores River. After gathering 

available information from literature, maps, and drill logs, a program of 

exploratory drilling was initiated in the summer of 1972. At that time 

five 3-inch-diameter core holes were drilled on the east side of the river. 

A more comprehensive drilling program was initiated in late 1972 in which 

a total of 12 holes was drilled on both sides of the river. 

In 1973 a test well and three monitoring wells were drilled to test 

the aquifers. Two 48-hour pump tests were conducted in October and December 1973, one in the alluvium and one in the residual gypsum cap. 

In the summer and fall of 1975 a ground water observation well network was installed, including piezometers of varying depths at 29 sites. 

At this time two additional test wells were drilled to pump from the gypsum cap. 

A 30-day aquifer test was conducted in January 1976 utilizing two of 

the three test wells (one test well did not produce sufficient brine to 

pump). 

In the summer of 1977, 18 test wells were installed in the alluvium 

as part of the design data collection program. Starting about September 

1978 and continuing for about 1 to 1~ years, the 18 wells in various combinations will be pumped, The pumping rates of each well will be adjusted 

in order to determine the most efficient pumping rate and pattern.

the brine inflow areas, is included on the following page •

CHAPTER II 

WATER RESOURCES 

Surface Water 

Surface water measurements were initiated in 1971 when three stream 

gaging and water quality sampling stations were established. The first 

station was located where the Dolores River enters the valley, about 1.5 

miles upstream from the brine seep area (Dolores River at Bedrock, Colo.); 

the second where the river leaves the valley, about 1.5 miles downstream 

from the brine seep area (Dolores River near Bedrock, Colo.); and the 

third on West Paradox Creek, 2.6 miles upstream from its mouth (West 

Paradox Creek above Bedrock, Colo.). These stations are being maintained 

by the Geological Survey. Except for West Paradox Creek, continuous flow 

measurements and weekly water quality samplings have been taken since 

1971 and are continuing at present. Problems with bank caving and maintaining a workable cross section were encountered with the gage on West 

Paradox Creek, and it was discontinued September 1973; however, the sampling station has been maintained. A sampling station was also established on the Dolores River approximately 5 miles below the confluence 

of the San Miguel River. · 

The Geological Survey maintains both stream gaging and water sampling 

stations on both the San Miguel River at Uravan and Dry Creek near Naturita. The location of the station on Dry Creek is on the main fork and 

is above the Radium Evaporation Pond site. 

Although no long-term streamflow records exist, partial records taken 

by the Geological Survey for the Dolores River at Bedrock are available 

for 1918 and 1922. Tabulations of the available streamflows for all pertinent gaging stations are shown in Tables 1 through 5. 

Dolores River 

The headwaters of the Dolores River are located on the south slopes 

of the San Juan Mountains and the west slopes of the La Plata Mountains. 

From its headwaters to the southeast of the unit area, the river flows 

in a southwesterly direction for about 50 miles, then makes an abrupt 

turn to flow in a northwesterly direction for about 115 miles to Paradox 

Valley and another 70 miles to its confluence with the Colorado River 

near Cisco, Utah. Under normal conditions the flows in the Dolores River 

are relatively low from July through March and high from April through 

June. 

For the Dolores River at Bedrock the average annual flow was 299,400 

acre-feet for 1972 through 1976, the years with continuous record. The

CHAPTER II WATER RESOURCES 

maximum discharge at this station was 9,280 cfs on April 30, 1973, and 

the minimum was 0 cfs on September 30, 1974. 

For the Dolores River near Bedrock for the same period, the average 

annual flow was 313,500 acre-feet. The increase in the flow of the river 

across the valley is due to the tributary inflow from West and East Paradox Creeks and relatively fresh and saline ground water inflow from 

springs and seeps. The maximum discharge recorded at this station was 

9,500 cfs on April 30, 1973; the minimum was 0.44 cfs on August 1, 1972. 

Dolores River flow patterns in Paradox Valley would be modified with 

the construction and completion of McPhee Dam, the main storage facility 

of the proposed Dolores Project located about 115 miles upstream from 

Paradox Valley. The construction of McPhee Dam should result in increased 

flows from August through November in wet and average years. In dry years 

the minimum releases would be such that they probably would not reach Paradox Valley, and streamflows would approximate historical flows. About 

1 year out of 4 would fall in this category. McPhee Dam would cause decreased or unchanged flows from December through July, and therefore, 

Dolores River flows through Paradox Valley should be more uniform than 

historically. The increased summer and fall flows would be produced by 

reservoir releases for downstream water rights and for improved fish habitat. Decreases in monthly flows would primarily occur while accumulating 

storage in McPhee Reservoir during the high spring runoff. The historical and modified flows immediately downstream from McPhee Dam site are 

shown in Table 6.

CHAPTER II WATER RESOURCES 

West Paradox Creek 

West Paradox Creek, formed on the eastern side of the La Sal Mountains in Utah by the confluence of Mellenthin and Buckeye Creeks, flows 

down to and through the western part of Paradox Valley and empties into 

the Dolores River in the middle of the well field area~ Water from Buckeye Creek is stored in Buckeye Reservoir (capacity 1~600 acre-feet) and 

is used along with natural flows in West Paradox Creek for irrigation in 

the upper portions of the valley. During the irrigation season, excluding the high spring runoff period and thunderstorms, the only flows in 

the creek reaching the Dolores River are small amounts of irrigation return flow. 

Dry Creek 

The headwaters of Dry Creek are about 20 miles south of Naturita, 

Colo, It flows in a northwesterly direction draining all of Dry Creek 

Basin and then flows north emptying into the San Miguel River 3 miles 

east of Naturita. The proposed Radium Dam and Dike are on small intermittent tributaries that drain into Dry Creek • 

Ground Water 

Paradox Valley 

Ground water level measurements in Paradox Valley were started in 

1971 on private wells and were expanded to include the Bureau-constructed 

wells as they were completed~ The Bureau of Reclamation's observation 

well network consists of ground water table observation wells and piezometers that measure the piezometric head at different points in the brine 

aquifer. A series of piezometers were placed just above the gypsum bedrock in the alluvial overburden 56 to 80 feet deep (piezometer No. 2), 

and another group was placed in the gypsum itself 225 feet deep (piezometer No, 1). For a detailed explanation of the observation well network, 

see Chapter IV. The measurements included water level readings of both 

ground water table and deep artesian aquifers. The measurements were usually taken on a monthly basis; however, when personnel were working in 

the area or when aquifer tests were being conducted, measurements were 

taken at more frequent intervals. On one well a continuous recorder was 

installed to monitor the water level fluctuations. 

Hydrographs showing water table levels and piezometric head elevations for selected wells throughout the well field area are shown in Figures 5 through 15. Measurements were started in mid-1972 for wells 2PX 

and 10CX, in mid-1973 for 6PX and 7PX, in early 1974 for 8PX, and in late 

1975 for lWl, 2W2, 4Wl, 2Cl, 2El, and 3El. Location of these wells is 

shown on the General Investigations Map on page 13.

CHAPTER II WATER RESOURCES 

In March 1977, the brine in all the piezometers that were constructed 

during 1975 was replaced with brine having a density of 1.165. This was 

done to eliminate discrepancies caused by density differences. When the 

piezometers were constructed, they were cleaned out and filled with the 

formation brine. Testing of the formation brine has since shown density 

differences. As can be seen on the hydrographs for piezometer No. 1 in 

2W2, 4Wl, 2Cl, and 2El and piezometers 1 and 2 in 3El, replacing the formation brine with a brine having a density of 1.165 caused a jump in water 

levels. This indicates that the formation brine had a higher density and 

thus higher salt content than the replacement brine. 

The greatest effect on the ground water system has been caused by 

high spring floodflows in the Dolores River and flooding on West Paradox 

Creek. This effect is shown on all the hydrographs during the period of 

April through June-of each year. Little effect is shown at 2PX because 

of the distance away from the river. The effects of the pump tests conducted in October and December 1973 on the water levels can be seen on 

the hydrographs for 6PX, 7PX, and SPX. The effect of the pump test conducted in January and February 1976 on the water levels can be seen in 

all the hydrographs except 2PX, lOCX, 4Wl, and 2Cl. Ice buildup on the 

flood plain and in West Paradox Creek and the ponding effect behind the 

ice on the west bank also affect water levels on the west bank and can 

be seen on the hydrographs usually during December, January, and February. During the pump test in January and February 1976, a large ice 

buildup occurred and then melted. The effect of this event can be seen 

on the hydrographs of 4Wl, 2Cl, and lOCX. 

Brine Aquifer 

Since 1972 the Bureau of Reclamation has accomplished considerable 

drilling on both sides of the Dolores River to determine the subsurface 

geology and ground water conditions in the brine discharge area. In addition, logs of private wells and exploratory drilling operations have 

been used to obtain information. Selected logs are shown in the Attachment Section pages 103 to 159, and all remaining logs are available in 

the Bureau's office in Durango, Colo. Well locations are shown on the 

General Investigations Map on page 13. 

The logs indicate that the Dolores River has deposited considerable 

amounts of alluvium over the underlying Paradox Member of the Hermosa Formation. These deposits were encountered at depths to 129 feet. The alluvial deposits are stratified varying from fine, poorly graded sand to 

clay-filled gravels just above the residual gypsum cap. Discontinuous 

clay lenses occur at irregular intervals throughout the deposits. 

The Paradox Member of the Hermosa Formation underlies the entire valley and is exposed in the eastern part as gypsum hills extending along 

the axis of the anticline. Along the river this member lies below the alluvial deposits. Drill hole information indicates that there is a general 

29 
•

• 

CHAPTER II WATER RESOURCES 

rise, or subsurface ridge, of the member extending along the middle of 

the valley in the well field area. The red contours of the map on the 

following page show elevations and locations of this ridge. The Paradox 

Member is predominantly salt, with arkose, carbonaceous shale, limestone, 

gypsum, anhydrite, and interbedded sandstone. The upper 650 to 1,000 

feet have been leached to form the residual cap of predominantly gypsum 

with large amounts of crumbly, gypsiferous, and carbonaceous shale that 

is extensively brecciated and mixed with other clastics. Underlying the 

residual cap, the halite (sodium chloride) rich core was determined to 

extend to a depth of 14,000 feet in a wildcat hole about 1 mile west of 

the brine inflow area. 

The most permeable brine aquifers are in the alluvial deposits and 

generally occur at about midway between the ground surface and the residual gypsum cap. The aquifers usually consist of fine, poorly graded sand 

but are sometimes sandy gravel. The discontinuous and erratic clay 

lenses form impermeable barriers which direct the flow of water through 

certain areas and create artesian conditions in places, but there is no 

extensive confining of the aquifers. The brine entering the river is derived from ground water circulating through fractured zones in the greatly 

faulted, folded, and brecciated residual gypsum cap until it comes in contact with the underlying salt core and thereby becomes brine. The extreme 

predominance of sodium chloride in the brine indicates that the source of 

salt is in the halite-rich salt core rather than in the leached residual 

cap. 

Brine appears to underlie the entire length of the Paradox Valley at 

varying depths. Along the Dolores River flood plain from about the middle of the valley to the exit from the valley, brine surfaces in the river 

channel in two general areas as shown in Figure 16 on page 32 and also on 

the first photograph on page 9. The drill log of a well operated by the 

Jensen and Jensen Brine Company about a mile west of the river shows the 

top of the brine zone between depths of 102 and 109 feet. The exact location of the top of the brine aquifer west of the Jensen brine wells is not 

known. Although two irrigation wells in the northwest end of the valley 

penetrated the Paradox Member for several feet, there is no report of 

brine being encountered. To the east of the river on the valley floor 

the brine varies from 10 to 50 feet beneath the surface. The investigations indicate that brine ground water converges toward the river from 

both the east and west portions of the valley. 

From water level and electrical conductivity measurements in the 

shallow water table observation wells, it can be seen that the freshwaterbrine interface slopes downward away from the river (see Figure 17 on 

page 33). The interface gradient is steeper toward the river on the west 

side than on the east side. 

Piezometric head measurements in two zones, one zone within the gypsum cap and one just above the gypsum cap, indicate that the brine

CHAPTER II WATER RESOURCES 

pressures are above the normal water surface of the river. See the green 

and blue contours of the map on the following page for the piezometric 

heads as measured in the gypsum cap and in the alluvium~ 

Freshwater Aquifer 

A significant layer of relatively freshwater overlies the brine in 

western Paradox Valley with a hydraulic gradient toward the river. The 

top of this water lies from 6 to 40 feet below the ground surface, depending upon the location. See the red cdntours of the map on the following 

page for the ground water table elevations. In the flood plain, the water table depth is generally from 4 to 10 feet below the ground surface. 

Estimated to be at least 100 feet thick about a mile west of the river, 

the thickness of the layer gradually decreases toward the river and pinches 

out in the area of.the surfacing brine. There are several irrigation 

wells in West Paradox Valley that pump from this freshwater source. 

On the east side of the river little, if any, freshwater overlies 

the brine. Approximately 3 to 3.5 miles southeast of the river in East 

Paradox Valley, however, there are two wells from which water is pumped 

for livestock watering • 

Freshwater springs near Bedrock on the west side of the river maintain a marshy area and feed some small impoundments (old river channel 

depressions). There are also two flowing springs just east of the river 

on the south side slope of the valley. Water from the spring nearest 

the river is piped to the Bedrock town site. 

Recharge Sources 

The brine and freshwater aquifers have a variety of potential recharge sources, including runoff from the La Sal Mountains, irrigation 

return flows from western Paradox Valley, seepage from West Paradox 

Creek, precipitation, and surface and subsurface runoff from the valley 

walls, Because brine evidently circulates through the salt core at 

depths of 650 feet or more before surfacing, it probably originates from 

the more distant recharge sources, while the freshwater originates from 

the nearer sources. 

It is possible that some of the brine that discharges in Paradox 

Valley may be derived from deep sources below the Paradox Member, but 

this contribution is believed to be negligible. An unpublished report by 

the Geological Surveyl/ gave the following reasons: (1} the salt beds 

probably have a very low hydraulic conductivity and thus could not transmit ground water at a significant rate; (2) the only significant aquifer

of all the pre-Paradox rocks is the Leadville Formation of Mississippian 

Age; however, a potentiometric map of this aquifer does not indicate that 

it discharges water in Paradox Valley; and (3) the Leadville Formation is 

overlain by the Molas Formation of early Pennsylvania Age, which in turn 

is overlain by the Pinkerton Trail (lower member of the Hermosa Formation), 

and these units form an effective seal between the Paradox Member and the 

Leadville Formation. 

Ground Water Discharge 

The total discharge from the springs and seeps along the banks and 

in the bed of the Dolores River in Paradox Valley appears to range from 

1.5 to 4 cfs. Directly measuring the discharge of the brine is impra~tical because of the large number of both fresh and brine springs and seeps, 

the diffuse natur~ of some of them, and the location of some in the riverbed. Consequently, the brine discharge has been calculated on the basis 

of total ground water inflow and total salt contribution, as follows. Samples of the seeps and springs have shown that they have either a low 

(1,500 mg/1} or high (250,000 mg/1 with a density of 1.16) salt content 

depending upon sampling location. There seems to be little inflow with 

a salt content in the middle range. Using monthly averages of salt pickup 

by the river calculated from data for the period August 1971 to September 

1976, the average daily salt pickup has ranged from a low of 115 tons per 

day to a high of 1,430 tons per day, as shown in Figure 18. In order to 

calculate the quantity of brine flowing into the river, it was assumed 

that the total salt picku~/ was from the brine springs and seeps, since 

only 16 tons per day would be added to the river if all the ground water 

were flowing into the river at 1,500 mg/1. At a concentration of 250,000 

mg/1, it would require a brine inflow in the range of 0.2 to 2.1 ~fs to 

contribute the 115 to 1,430 tons per day. 

The brine ground water inflows to the river exhibit a degree of seasonal fluctuation, generally being at its lowest during the spring or summer and at its highest during the fall and winter. 

Dry Creek Basin 

Mancos Shale underlies most of the area of the proposed Radium Evaporation Pond extending from the base of the northeast ridge of Dry Creek 

Basin to the southwestern extremities of the pond site. Dakota Sandstone 

is exposed at intervals along the northeast slope of Dry Creek Basin between the proposed sites for Radium Dam and Dike. Stream deposits, residual soil, and a small amount of eolian soil comprise the overburden of 

the pond site. The stream deposits consist mostly of sand and silt with 

occasional gravel- to boulder-sized detritus from local sedimentary formations. Beyond the streambeds~ the site is overlain by a relatively thin 

11 The pickup is from ground water inflow to the river and does not 

include any salts in the flows from West Paradox Creek.

covering of silt~ lean clay, and fat clay derived from Mancos Shale. for 

the most part; it contains, however, weathered sandstone and sand layers 

from Dakota Sandstone along the northern fringe of the pond site. The 

residual soil derived from Mancos Shale sometimes has zones of soluble 

carbonate and/or sulfate mineral concentrations which are also typical 

of the parent material. Eolian soil of reddish-brown silt and lean clay 

often forms the upper 1 to 3 feet of overburden. No faulting or folding 

other than the major structure of Dry Creek syncline was observed at the 

site. 

Water seeps in the West Fork and East Fork of Dry Creek indicate the 

water table to be at or near the elevation of the streambed. Drill hole 

4RA in the West Fork of Dry Creek co~tacted the water table at a depth of 

11.8 feet, and drill hole 7RA in the East Fork of Dry Creek had a slight 

artesian flow at 1~2 feet above ground level (see Map 1294-400-25 on the 

following page). The U-shaped warping of formations in the Dry Creek Basin syncline has created the artesian effect. The Dakota Sandstone serves 

as an aquifer overlain by impermeable Mancos Shale and underlain by impermeable Burro Canyon shale and mudstone. The Dakota aquifer is charged 

with water on the upturned flanks of the syncline. The power auger holes 

drilled in the pond basin were. dry except for some water seepage at 14 

feet in AP-8RA and at 9.9 feet in AP-17RA. Water level in core holes 

drilled in the pond basin ranged from about 4.5 to 24 feet (see logs in 

the Attachment Section on pages 160 through 168). A 607-foot-deep water 

well, drilled by the Bureau of Land Management at elevation 6,353 feet, 

located water in shale from the 65- to 100-foot depth and in sandstone 

at depth intervals of 450 to 460 feet, 490 to 500 feet, and 529 to 530 

feet. This well and an oil-gas well which were converted to stock watering are shown on the following page .

CHAPTER III 

WATER QUALITY 

Surface Water 

The salinity of the streams in the project area varies considerably 

because of the large fluctuations in flows and in the volume of saline 

ground water entering some of the streams~ Salt concentrations are generally low during high runoff but increase progressively as the flows decrease. Water quality sampling stations are maintained on all the streams 

in the project area. Results of this sampling and other quality investigations are presented in this chapter. 

Dolores River 

Several times a year the electrical conductivity of the water in the 

valley was measured at intervals along the full length of the Dolores 

River on the same day. Also, measurements of seeps and springs were taken 

along the river banks. The measurements were obtained by using a portable 

conductivity meter and walking down the river. The investigations indicated where saline waters (possible irrigation return flows) and brine 

springs were entering the river. Two areas of concentrated brine inflow 

have been identified--one area in the river at about the valley midpoint 

approximately 2,600 feet long referred to as the upper area and the second area at the lower end of the valley approximately 1,200 feet long referred to as the lower area. These areas are identified in Figure 16 on 

page 32. The salinity measurements have indicated that approximately 75 

percent of the salt pickup is entering the river in the upper area and 

25 percent in the lower area. Figure 19 shows the percent increase in 

salt loading as the river crosses the valley and is plotted in terms of 

percent change of total salt loading. At the Bedrock Bridge where the 

river enters the valley, the percent change would be equal to zero, and 

where the river leaves the valley the percent change would be equal to 

100 percent. In general, the salinity measurements were made during periods of low river flows. 

In the fall of 1975, four continuous recording electrical conductivity meters were set up along the Dolores River in Paradox Valley located 

as follows: one just above the upper brine s.eepage area (EC Recorder No. 

1), one between the upper and lower brine seepage area (EC Recorder No. 2), 

one just below the lower brine seepage area (EC Recorder No. 3), and one 

at the Dolores River near Bedrock stream gaging station (EC Recorder No. 

4). Locations of these recorders are shown on Figure 19. In the summer 

of 1976, a fifth EC Recorder was set up at a location just above the Dolores River at Bedrock stream gaging station (EC Recorder No. 5). The 

electrical conductivity ranges of the recorders are shown in the tabulation on page 42.

CHAPTER III WATER QUALITY 

EC Recorder No. 5 0- 3,000 micromohes/cm 

EC Recorder No. 1 0- 10,000 micromohes/cm 

EC Recorder No. 2 0- 50,000 micromohes/cm 

EC Recorder No. 3 0- so,ooo micromohes/cm 

EC Recorder No. 4 0-100,000 micromohes/cm 

Reasonably good results have been obtained from the recorders. There 

have been some problems with trash collecting on the probes or with sand 

shifting in the bottom of the river, causing the flow in the channel to 

change locations. During periods of high spring runoff, the recorders 

have been taken out of operation in order to prevent damage to the probes. 

Each time the recorders are serviced a water sample has been taken near 

each site and sent to the regional laboratory in Salt Lake City for analysis. Results of the chemical analysis of the water samples are used to 

interpret the recording charts_ to check if the meter is operating correctly, and to determine the constituents of the dissolved solids in the 

water, 

The recorders have been used to determine changes in the river salinity during periods of pumping, and in conjunction with the gaging and water sampling program, to better estimate the amount of salt being picked 

up in the valley. The data have shown that the electrical conductivity 

can change greatly during a 24-hour period. This is especially true during the winter months when freezing and thawing of the river is occurring 

above and through the valley and when the flow in the river is increasing 

or decreasing. 

As stated in Chapter II, water sampling stations have been established at three locations on the Dolores River. In addition, various 

other State and Federal agencies have taken samples at various locations 

on the river within the project area. 

Water samples collected on the Dolores River at Bedrock show dissolved oXygen and pH concentrations are compatible with biological productivity. Occasional high temperatures, high turbidity, and low flows, which 

occur most of the year, inhibit Lhe productivity and diversity of the 

stream. The turbidity in the river, contributed largely by tributaries, 

is caused by natural erosion and man-caused soil disturbances. Nutrient 

levels are moderate. Occasional high levels of phosphorus and fecal coliform indicate the presence of upstream sewage discharges but do not cause 

problems of eutrophication. On occasion, small amounts of heavy metals 

and toxic substances are present in varying concentrations, primarily because of erosion, They would not prohibit the use of the water for livestock, although extensive treatment would be required for human consumption. Because of the temperature and chemical factors and their interaction, it is probable that heavy metals and toxic substances would remain 

in chemical forms unavailable for biological uptake. Data showing the 

amounts of the parameters stated above are shown in Table 7~

CHAPTER III WATER QUALITY 

Salt pickup by the Dolores River is the major water quality problem 

in the project area. According to samples collected by the Bureau during 

a 5-year period, the salt concentration of the river at the entrance to 

the valley has ranged from 140 mg/1 to 3,700 mg/1 with a flow-weighted 

average of 264 mg/1. The predominant constituents have been sulfate, bicarbonate, chloride, sodium, and calcium. At the exit of the valley, 

the salt concentration has ranged from 150 to 166,000 mg/1 with a flowweighted average of 729 mg/1. The high concentration of salt in the 

river at the exit of the valley occurs when there is no flow entering the 

valley, and the water in the channel leaving the valley is composed entirely of surfacing ground water and irrigation return flow. The predominant constituents at the exit have been sodium and chloride. Table 7 

on pages 43 through 46 shows the laboratory analysis of the samples collected on the iiver in Paradox Valley. 

Using both quality and quantity data, it was calculated that the total salt load at the exit of the valley has averaged about 312,000 tons 

annually. This is approximately 205,000 tons larger than the average load 

at the entrance to the valley. The daily salt pickup varied from 115 to 

1,430 tons per day and has averaged about 560 tons per day. The rate of 

salt pickup in Paradox Valley is shown on Figure 20. As stated above, 

the concentrations of sodium and chloride increase considerably as the 

river crosses the valley, with averages of 195 tons and 315 tons, respectively. Figure 21 on page 49 shows the rate and amounts of sodium and 

chloride that are picked up in the valley. 

Salt pickup between the two sampling stations in the valley exhibits 

a degree of seasonal fluctuation, generally being at its lowest during 

the spring and summer and at its highest during the fall and winter. (See 

Figure 18, page 37.) It also appears that the amount of water in the 

river affects salt pickup. Salt pickup was at a minimum for the year during the spring of 1973, when flows in the river were unusually high. There 

is indication that initial high flows occurring in the fall flush salt out 

of the river channel that has accumulated during the drier summer months. 

In addition to the sodium and chloride concentrations, other water 

chemistry parameters show large increases as the Dolores River flows 

through Paradox Valley. These parameters include electrical conductivity, 

total dissolved solids, and sodium adsorption ratio as well as calcium, 

sulfate, potassium, and magnesium. 

The quality of the Dolores improves considerably because of the inflow of relatively freshwater below the confluence with the San Miguel 

River. Samples collected (Table 7 on pages 43 through 46) from September 

1974 through May 1976 about 5 miles below the confluence had a flowweighted average salinity of about 659 mg/1, with extremes of 171 and 

7,920 mg/1 •

CHAPTER III WATER QUALITY 

West Paradox Creek 

West Paradox Creek has been sampled since 1971 on a weekly to biweekly basis, During the sampling period~ the salinity has a flow~weighted 

average of about 800 mg/1 and has varied from 262 to 1,970 mg/1. The water contains predominantly sulfate, bicarbonate, calcium, and magnesium 

which is characteristic of waters containing irrigation return flows. Results of the sampling on West Paradox Creek are presented in Table 7 on 

pages 43 through 46. It is estimated that the creek contributes an average of about 14 tons of salt per day and 7,000 tons per year to the Dolores River. 

Dry Creek 

Samples have been taken from Dry Creek at its confluence with the 

San Miguel River near Naturita, Colo., since 1960. The flow-weighted average salinity for this period has been 1,460 mg/1 and has varied from 

414 to 9,800 mg/1. Table 7 on pages 43 through 46 presents results of 

the quality analysis. Sampling will continue at this station below the 

proposed Radium Evaporation Pond after the project is constructed to substantiate that no leakage is occurring from the pond . 

Ground Water 

Paradox Valley 

The quality of the ground water in Paradox Valley ranges from a 

brine, having a density of lal64, a salt content of 23 percent or greater 

of which 93 percent is sodium chloride, to moderately saline water in the 

shallow aquifers on the east and west sides of the river, to freshwater 

along the edges of East and West Paradox Valleys. Analyses of samples 

collected from the wells, seeps, and springs are given in Table 8. 

Only a very small percentage of the ground water in the valley can 

be classified as fresh. Springs along the valley walls and Windmill Well 

No. 2 in East Paradox Valley contain approximately 300 to 500 mg/1 total 

dissolved solids with a large percentage of bicarbonate salts. 

All of the irrigation wells in Paradox Valley that were sampled can 

be classified as slightly to moderatly saline. Depending upon the time 

of year that they were sampled, TDS values ranged from 1,400 to as high 

as 3,500 mg/1. Windmill Well No. 1 in East Paradox ranged from 4,500 to 

5,400 mg/1. Seeps from the west bank of the Dolores River above the salt 

submergence area have ranged from 1,500 to 4,000 mg/1. A large percentage of the salts in the samples is calcium, magnesium, and sulfate. Samples from the seeps in the Dolores River and the samples from the Redd 

Irrigation Well No. 2 toward the end of the irrigation season after the 

well has been pumped heavily for some time show larger percentages of sodium and chloride, indicating some mixing with the underlying brine.

CHAPTER III WATER QUALITY 

A sample taken from an open pit approximately 0.5 mile east of the 

river contained 117.500 mg/1 TDS with a large percentage of the TDS being sodium chloride, indicating that brine remains near the surface in 

East Paradox Valley. Seepage flow into the Dolores River in the submergence area contains brine in the range of 250,000 mg/1. The brine in 

wells near the Dolores River that taps the brine aquifer has a salt content in the range of 252,000 to 296,000 mg/1 TDS. 

On a field trip to Paradox Valley, personnel from the Geological Survey collected a brine sample from a seep adjacent to the Dolores River in 

the lower portion (center of sec. 9, T, 47 N., R, 18 W,) of the brine 

seepage area for chemical analysis at the Geological Survey laboratory in 

Reston, Va. Results of the analysis are given in Table 9. It reported 

no other trace metals other than those reported could be detected using 

the atomic adsorption method and selenium could not be detected using the 

colorimetric metbod, An analysis of a hydrochloric acid extract of the 

sediment that had collected on the river bottom in the brine seepage area 

indicated the presence of iron, copper, a trace of zinc, but no cadmium, 

nickel, or cobalt. The sediment was mainly medium- to fine-grained quartz, 

with coatings of iron sulfide.

CHAPTER III WATER QUALITY 

The brines from both 7PX and Test Well No, 1 have been analyzed for 

oil content. A sample from 7PX was collected and sent to the Engineering 

and Research Center for analysis during 1974. Brine from Test Well No. 1 

was analyzed for oil content in 1976. No trace of oil above a detection 

limit of 1 mg/1 was found in either sample. 

The brine from Test Well No. 1 was also analyzed for the presence of 

radioactivity. A gamma radiation measurement with detection sensitivity 

of 0.47 x lo-12ci/ml found no indication of the presence of gamma emitting radioisotopes~ A measurement for total alpha and beta radiation of 

a dried sample gave a similar indication. Present data indicate that 

there is not enough radioactivity present in the brine to constitute any 

hazard, even through concentration by evaporation. 

Hydrogen sulfide gas is also associated with the brine, Bubbles of 

hydrogen sulfide gas can be seen surfacing anywhere in the river where 

brine seeps and springs exist. Anaylsis of brine samples that have been 

kept under pressure and not exposed to .the atmosphere has shown the brine 

to contain approximately 100 mg/1 of dissolved hydrogen sulfide gas. When 

the brine is pumped and discharged to the atmosphere some of the gas is 

released • 

Dry Creek Basin 

Sampling of the ground water in Dry Creek Basin (Table 11) has indicated that the proposed Radium Evaporation Pond is underlain by fresh to 

slightly saline water. The major salts encountered in this ground water 

are sodium, sulfate, and bicarbonate. As described in the Radium Evaporation Pond Section of Chapter IV, a quality monitoring system of eight 

wells would be installed before the construction of the proposed evaporation pond. Monitoring would continue after its construction to substantiate that no salt leakages occur. 

Unit Effects 

By preventing the annual inflow of 180,000 tons of salt, the unit 

would effectively remove about 90 percent of the salt now entering the 

Dolores River in Paradox Valley. This salt removal would be reflected 

downstream in the Dolores River and in the Colorado River below their 

confluence. The overall effect would be to decrease the salinity of 

the Colorado River at Imperial Dam. As Table 12 on page 56 shows, the 

amount of the average annual reduction would gradually decrease to about 

18.2 mg/1 in the Colorado River at Imperial Dam. Seasonal variations 

would also be buffered downstream, since regulatory reservoirs on the 

Colorado River have reduced the seasonal fluctuations in flow •

The unit would decrease the average annual flow-weighted salinity of 

the Dolores River by about 474 mg/1 at the exit from Paradox Valley, or 

about 65 percent below existing conditions. The largest reductions would 

occur in the concentrations of sodium and chloride, with relatively small 

reductions in sulfate, potassium, magnesium, calcium, and various heavy 

metals (particularly iron and lead). 

The reduction in the concentration of total dissolved solids would 

vary considerably on a seasonal basis because of the large fluctuations 

in streamflow. During the spring, when the salinity is normally low because of the dilution effect of high snowmelt runoff, the unit would improve the quality of the river leaving the valley by 30 mg/1. During 

normal to low flows, however, this improvement could range from 5,000 to 

160,000 mg/1. Overall, the water quality of the river would be about the 

same just below the valley as it is just above. West Paradox Creek and 

irrigation return flows would still contribute small amounts of salt. 

The unit would have no effect on the water quality of the San Miguel 

River. Radium Evaporation Pond would retain and evaporate all of the 

brine, with no leakage to influence either Dry Creek or the San Miguel 

River .

CHAPTER IV 

UNIT PLAN AND DESIGN 

Brine Well Field 

Pump testing 

In 1973 Test Well No. 1 (DH-23CX on General Investigations Map on 

page 13) was drilled to a total depth of 300 feet, penetrating through 

100 feet of lenticular river deposits and 200 feet of the brecciated gypsum cap of the salt dome. Pump tests were conducted in October and December 1973 in two.brine producing aquifers consisting of the alluvial 

zone of sand, silt, and gravel deposits and the underlying zone of fractured gypsum breccia. Data from these tests gave hydraulic aquifer characteristics as sununarized in Table 13. Because of the short test duration (48 hours) and the small area monitored during the tests, the data 

were insufficient to design a full-scale well field. Later pump tests 

have shown that the permeabilities in the deep, coarse gravel deposits 

just overlying the gypsum cap are low and that the permeabilities in the 

gypsum breccia are very low. Possible leakage around the casing from the 

sand and gravel zone to the deep zone could have influenced the pump test 

involving the deep zone and given incorrect results. 

In 1975 NX core holes were drilled to locate sites for test wells 

which could be used to investigate the possibility of pumping brine from 

the residual gypsum breccia cap of the s·al t dome. Two of the sites were 

selected for proposed test well locations (Test Wells 2 and 3). Drilling 

the test wells was accomplished by drilling and advancing a 20-inchdiameter steel casing through the alluvium and drilling open hole in the 

gypsum breccia zone. Pump chamber casing and 200 feet of fiberglass reinforced plastic screen were placed in each well. Upon developing each 

well, it was found that Test Well No. 3 would produce less than 10 gallons per minute and Test Well No. 2 would produce approximately 30 gallons per minute. In addition to drilling the new wells, Test Well No. 1 

was modified so only the deep aquifer could be pumped. 

A 34-day aquifer test was conducted, utilizing Test Wells 1 and 2, 

and the results of the test from selected observations wells are listed 

in Table 13. In addition to observing the ground water system, the electrical conductivity at several locations on the river was also monitored 

for change in river salinity. Brine from the wells pumped during the test 

was piped to a temporary storage pond located at the lower end of the 

valley. Results from the test indicated that permeabiJities in the gypsum breccia were very low, the amount of brine required to affect the 

brine aquifer could not be obtained from pumping from the gypsum breccia 

zone, and that pumping from the alluvium aquifer is the best alternative.

CHAPTER IV UNIT PLAN AND DESIGN 

The hydrographs presented in Chapter II for Observation Wells 6PX, 7PX, 

and 8PX show that by pumping from the brine aquifer the potentiometric 

head of the brine can be lowered in relation to the overlying freshwater 

zone, and therefore the freshwater-brine interface can be lowered. 

Brine production wells 

The Paradox Valley Unit would be designed to control salinity by 

pumping brine from a well field located on both sides of the Dolores 

River. Initially the well field would consist of 18 production wells 

with 10 wells on the west bank and 8 on the east bank. The wells surround two brine producing areas--one in the center of section 16 (upper 

area) and one in the center of section 9 (lower area)--where investigations indicate the major portion of brine is entering the river. (See 

Figure 16 on page 32.) There would be 13 wells surrounding the upper 

area and 5 surrounding the lower area. Additional wells would be constructed if it is determined after the field has been put into production 

that they would improve the efficiency and economics of well field operation, 

All the wells except one would be designed to pump from an alluvi.al 

aquifer consisting of fine sand and gravel. Depth of wells in the alluvium would vary from 48 to 77 feet. One well would be drilled into the 

residual gypsum cap to a depth of 155 feet in order to pump from a cavity 

at 133 to 140 feet and intermittent small cavities from 140 to 150 feet. 

The wells would have a total diameter of 20 inches with pump chamber 

casings having a diameter of 12 inches, the lower 15 to 40 feet of which 

would consist of commercial screens made from one of three materials--

Type II polyvinyl chloride, epoxy filament wound fiberglass, or stainless 

steel~ Gravel pack would be placed around the casing for its entire 

depth, both for stabilization and for excluding fine sand from the well. 

Table 14 gives the details of the wells that were installed as a part of 

the design data collection program. (See Figure 22 for typical test well 

installation.) 

The well casing, which would extend 4 feet above the ground, would 

have a concrete pad around it at the ground surface and would be housed 

in a protective structure to prevent damage from floods and vandalism. · 

The structure would have a removable roof in order to pull the pumps for 

repairs. Each pump would have an electrical control panel and would have 

observation pipes where the water levels, both inside and outside the 

well casing, could be measured. Each well would also have a pressure control valve, a manually operated control valve, a check valve, a flowmeter connection, and sampling taps to sample the quality of brine being 

pumped. The operator would be able to control the pumping rate and each 

well would have a demand meter to record power consumption. Power consumption records would be used to determine when the pumps need servicing 

or replacing. Design of the pumps will be determined during the design 

data collection program.

CHAPTER IV UNIT PLAN AND DESIGN 

Collection system 

Buried pipelines on each side of the river would collect the brine 

from each well and convey it to the Hydrogen Sulfide Stripping Plant. The 

line on the west would cross the river near Well No, lE and connect with 

the line on the east side. The connection at each well site would be 

equipped with a pressure regulating valve so if any one well were to shut 

down, it would not affect the total system. 

The collected brine would then be conveyed to the stripping plant 

in a buried pipeline. The diameters of the pipelines will vary, depending on their location in the collection system. The pipeline running 

from the well field to the stripping plant will be approximately the same 

size as the pipeli.ne running to the evaporation pond (i.e., 15 inches in 

diameter). Exact sizing of the pipeline will be de~ermined after the design data collection program is completed. 

Ground water monitoring wells 

A network of ground water monitoring wells has been installed during a series of drilling programs (see Chapter V). These observation 

wells are located near the brine production wells on both sides of the 

river and would be used to determine the effects of the pumping on the 

water table, the freshwater-brine interface, and the brine movement in 

the aquifer. The information obtained from the observation wells would 

be used to establish effective pumping rates and patterns for the production wells. 

The monitoring system contains two types of wells. The first consists of shallow wells, generally about 20 to 25 feet deep and 1.5 inches 

in diameter, with PVC casing well screens placed between depths of 10 and 

25 feet to allow ground water to enter the casing. Electrical conductivity meters could be lowered into the wells, and the conductivity measured 

periodically to determine the approximate depth of the fres~water-brine 

interface. A total of 39 of these wells of this type has already been 

drilled, and an undetermined number would be added as needed during the 

data collection program. 

The second type of wells consists of 26 wells drilled to an average 

depth of about 225 feet and 3 drilled to about 300 feet. Each well contains two or three pipes of different lengths, with each pipe perforated 

in a different zone to allow ground water to enter from that point in the 

aquifer. The area between the perforated portions is permanently grouted 

to prevent any mixing of water from the various zones. Figure 23 on the 

following page shows a typical monitoring well installation. 

Each of the 26 wells drilled to 225 feet contains 3 pipes. One pipe 

has an average depth of 25 feet and is perforated from 5 to 25 feet deep 

for use in observing the water table and, with electrical conductivity

meters, in locating the freshwater-brine interface. The second pipe is 

a piezometer extending to a depth of between 56 and 120 feet to the base 

of the alluvial aquifer, with the lower 5 feet perforated, By measuring 

how high the water entering the pipe is forced above the perforated section, the ground water pressure head in this patt of the aquifer can be 

determined. The third pipe, extending into the gypsum bedrock that forms 

the residual cap of the salt dome, has a depth of from 215 to 225 feet 

and is perforated for the lower 5 feet. This pipe is also a piezometer, 

with measurements of the water elevation indicating the ground water 

piezometric head. 

The remaining three wells, drilled to a depth of 300 feet, all contain a water table observation pipe about 25 feet deep and two have a 

piezometer pipe between 285 and 300 feet deep. The other well contains 

a piezometer pipe about 60 feet deep. Seventeen other wells in the valley that were drilled during earlier exploratory investigations are also 

being monitored. 

During both the pumping tests and long-term operations, these wells 

would indicate changes in the ground water system near the river. The 

shallow wells and pipes would be used to meas~re the lowering of the water table and the freshwater-brine interface, while the piezometer pipes 

would be used to evaluate pressure changes at deeper zones in the aquifer 

which would indicate changes in ground water movement. 

The well casings extend about 3 feet above the ground surface and 

were constructed with steel caps to prevent debris from entering and to 

discourage vandalism. All of the water table wells and piezometer pipes 

are read periodically to monitor water level changes. Some of the wells 

would have continuous recorders installed to monitor and record changes 

in the ground water system. Using the data from the observation wells, 

the well field operator would be able to adjust the pumping rate at any 

site and thereby operate the well field in an effective manner, minimizing pumping freshwater from the wells. 

River monitoring system 

To determine the overall effectiveness of the brine removal, the 

river would be monitored on a continuous basis at several locations. The 

five electrical conductivity meters described in Chapter III would be 

used during the design data collection program and during unit operation 

to monitor the electrical conductivity of the water in the river where 

it enters the valley, both upstream and downstream from the brine emerging areas and where the river leaves the valley. During servicing of the 

salinity meters, water samples would be taken and analyzed in the laboratory to determine the types and amounts of salt that are in the river water. The results of the samples would also be used to keep the meters 

calibrated. Streamflow gaging stations, both above and below the valley, 

will be maintained to keep a record of the flow entering and leaving the

valley. Water samples taken each week at the two gaging stations would 

be used to substantiate the accuracy of the meters and to measure the 

change in the chemical makeup of the water in the river, 

Flooding in well field 

The well field would be susceptible to flooding during high runoff 

years; water depths and velocities in places other than the river, however, will be low~ Flood studies done in the valley indicate that the 

maximum water level in the well field area during the 100-year flood 

would be less than 4 feet. Facilities in the well field would be protected against flooding. The frequency flood peaks are shown in the following tabulation.

Design Data Collection Program 

The feasibility estimates used in the Definite Pl&n Report and the 

Environmental Impact Statement are based upon the extreme condition that 

5 cfs of brine with a salinity of 260,000 mg/1 would be pumped constantly 

during the 100-year life of the unit to control the brine inflow to the 

Dolores River, Such an operation is unlikely, however, since only about 

0,9 cfs at that concentration is enough to produce essentially all the 

198,000 tons of salt that is now entering the river each year from ground 

water, 

If it were ultimately necessary to pump at this rate and concentration, six times more salt would be pumped than the amount entering the 

river. Although it is unlikely that this would be necessary, insufficient data exist to select a design rate. Contributing to the uncertainty 

is the lack of a complete understanding of the aquifer and recharge 

source; the need to remove a large reservoir of brine around and beneath 

the river to lower the freshwater-brine interface; and the possibility 

of pumping inefficiencies and, therefore, the need to mine some salt to 

achieve the desired results. For these reasons, it was decided to use 

the extreme condition for the designs and estimates in the Definite Plan 

Report and the Environmental Impact Statement. 

The Bureau of Reclamation is now conducting a design data collection 

program which is scheduled for completion in 1979. The purposes of the 

program are to test a well field that would effectively lower the 

freshwater-brine interface and reduce the brine inflow to the river; to

CHAPTER IV UNIT PLAN AND DESIGN 

determine a design pumping rate for each well and for the entire well 

field; and to determine the final design capacities of the Hydrogen Sulfide Stripping Plant, brine pipeline~ pumping plants, and evaporation 

pond, 

As part of this program 18 brine production wells were drilled, and 

short, 8-hour pump tests were conducted during the summer of 1977. Starting in 1978 and continuing for approximately 1 to 1~ years, all 18 wells 

and combinations of them will be pumped. The brine will be conveyed 

through a temporary pipeline to a temporary storage pond on the north 

side of the valley, west of the river. During the pump test, the ground 

water monitoring wells will be used to evaluate changes in the ground water system. Using the data obtained from the observation wells, the pumping rates of the wells will be adjusted as necessary to determine the most 

efficient pumping rate and pattern. Measurements in the monitoring wells 

will include water level readings to measure pressure variations and conductivity readings to measure the location of the freshwater-brine interface. Upon completion of the design data collection program, it is contemplated that the 18 existing production wells and the temporary pipeline would, with slight modifications, be converted to permanent operation. 

The river monitoring system with recording electrical conductivity 

meters, gaging, and sampling stations would help to assess the changes in 

streamflow and water quality that will occur as a result of pumping the 

brine. 

Environmental assessments and negative determinations have been prepared for the various stages of this work in compliance with the National 

Environmental Policy Act of 1969. The Environmental Protection Agency 

has given its approval to proceed with the testing program. 

Radium Evaporation Pond 

Radium Evaporation Pond would be formed by a dam across a tributary 

of the West Fork of Dry Creek and a dike across a tributary of the East 

Fork of Dry Creek. These tributaries are normally dry except for short 

periods of spring runoff and during thunderstorms. The pond would have 

a total capacity of 93,340 acre-feet, with an inactive storage capacity 

of 62,060 acre-feet, a dead storage capacity of 6,040 acre-feet, a flood 

control capacity of 18,700 acre-feet, and a surcharge capacity of 6,540 

acre-feet. The pond storage allocations are sunnnarized in Table 15. The 

top of the inactive pool would be at an elevation of 6,333 feet and would 

have a surface area of 3,295 acres. The dam would have an outlet works 

at elevation 6,274 feet. The outlet works would be used primarily for 

safety and draining during construction and would be covered by precipitated salt after a few years of operation. The basin is divided by a saddle into two ponded areas, with the west basin having a capacity of 16,690 

acre-feet and a surface area of 1,200 acres and the east basin having a

capacity of 5,920 acre-feet and a surface area of 592 acres. At an elevation of 6,316 feet, the two ponds would merge into one large pond. Because there would be no outlet works at the dike, the east basin is considered to be all dead storage (5,920 acre-feet). The west basin would 

have a dead storage of 120 acre-feet. 

Blanketing 

The major portion (83 percent) of the evaporation pond area is underlain by impervious Mancos Shale, which in some places exceeds 200 feet in 

depth. No blanketing or treatment would be needed in this area for a watertight pond. The other 17 percent of the pond area is underlain by Dakota Sandstone with a clay layer of varying thickness on top of the sandstone. In places,. the sandstone is exposed. It has been determined that 

about 640 acres will require a 5-foot, compacted earth blanket to eliminate seepage. Figure 24 indicates the area to be blanketed. 

Sufficient ground water monitoring wells would be drilled adjacent 

to the pond to measure the water table, hydraulic pressure, and water 

quality, substantiating that brine was not seeping into the local ground 

water system. Tentative location of these wells is shown on l',igure 24. 

Two wells would be located immediately downstream from the dam on either 

side of the tributary to the West Fork of Dry Creek, and two would be located just downstream from the dike on either side of the tributary to 

the East Fork. Three wells would be drilled between the dam and dike on 

the north side of the pond, and another would be located on the south side 

of the pond. Each well would contain one pipe 25 feet deep and another 

about 60 feet deep. The shallow pipe would have a screen from 5 feet to 

25 feet to permit observation of the water table, and the deep pipe would 

have a 5-foot screen on the bottom to measure the pressure head in the 

aquifer, Readings and sampling would be conducted monthly. 

Sedimentation 

The total sediment inflow to Radium Evaporation Pond would be 2,400 

acre-feet for the 100-year operational life of the project. The volume 

that this sediment would occupy is considered in the operation study as 

reservoir volume not available for precipitated salt. 

Inflow design flood 

The design annual inflow to Radium Reservoir is presented in Figure 

25 on page 70 and would have a total annual volume of 22,200 acre-feet. 

The inflow design flood consists of three events, the hydrographs for 

which are presented in Figure 26 on page 71. The first event is a 100-

year thunderstorm with a peak of 10,600 cfs and a volume of 890 acre-feet. 

This event is followed 24 hours later by the design thunderstorm event, 

which has a peak of 39,300 cfs and a volume of 5~020 acre-feet. A third 

flood event, representing the 50-year thunderstorm, follows the maximum

probable event by 24 hours. This event has a peak of 9,400 cfs and a volume of 750 acre-feet, The total 60-hour volume for inflow design flood 

is 6t660 acre-feet. 

Precipitation 

Two years of precipitation data ate available for Dry Creek Basin, 

with an average annual rate of 8.5 inches (see-Weather Station Summary 

Data in the Attachment Section on pages 169 to 173). The average annual 

precipitation for the same 2 years at Norwood, Colo., which is the closest station with a longer period of record, is 12.1 inches. Natural vegetation near the two stations indicates that the rainfall at Dry Creek 

Basin is significantly less than at Norwood. For the operation study 

the ratio for the 2 years of record of 0.7 for the two stations was assumed to be correct. The average annual long-term precipitation rate 

for Norwood is 14.9, giving a synthetic long-term rate of 10.4 for Dry 

Creek Basin. Table 16 shows the synthetically generated precipitation 

for Dry Creek Basin. 

Evaporation rate 

Two years of freshwater-pan evaporation data were available for Dry 

Creek Basin (1975 and 1976). For these 2 years, the average pan evaporation was 55.2 inches compared to 42.1 inches at Montrose station where a 

long period of record is available (see Table 17 on page 74 ). The Radium 

Evaporation Pond site, located in Dry Creek Basin, is about 500 feet 

higher in elevation than Montrose, but there is considerably more wind 

in Dry Creek Basin that is normally from the southwest and very dry. 

These winds would maintain a low vapor pressure over the pond area much 

of the time. Because brine does not freeze, except at extremely low temperatures, evaporation would go on throughout the winter months. For the 

Montrose station, the winter evaporation rates were filled in by use of 

a correlation with temperature. The synthetically derived average annual 

pan evaporation rate for Montrose, assuming no winter freezing, is 58.3 

inches for the 36-year data collection period. Because of the lack of 

sufficient data at Dry Creek Basin, it was decided to use this Montrose 

average in the operation study. This is a conservative estimate because 

if the proportion for the 2 years of concurrent data holds, the annual 

evaporation rate at Dry Creek Basin would be 76.0 inches. The evaporation rate is not critical because even at the Montrose rate sufficient 

surface area is available during the later years of operation to evaporate all accumulated brine and inflow. The critical factor for sizing 

the reservoir is the volume occupied by precipitated salts. 

To convert the freshwater evaporation rate to a brine evaporation 

rate, a reduction factor is used which varies from 1 to 0.71, depending 

on the percent of salt in solution. A revtew of available literature supported the use of 0.71 at saturation. The saturation concentration used 

was 29.2 percent salt, equal to that of Great Salt Lake brine at

CHAPTER IV UNIT PLAN AND DESIGN 

saturatton • ..!/ After a few years of operation, the constituents of salt 

in Radium should be in similar proportions to those found in the Great 

Salt Lake. !:../ 

Operation study 

A eomputer model was used to simulate the operation of the evaporation po~:td over its 100-year life. A computer printout with accompanying 

column descriptions is included in the Attachment Section on pages 82 

through 102. For the purpose of the operation study, 5 cfs of brine at 

260,000 mg/1 were assumed to be pumped constantly for the entire 100 

years. The use of this assumption for the sizing of project facilities 

is based on the extreme condition. Upon completion of the design data 

collection program in 1979, the operation study will be redone with a 

more accurate flow rate and salinity concentration. Sizing estimates 

will tl:.en be revised, and Radium Evaporation Pond will, undoubtedly, be 

reduceC. in size. 

In the operation study, Pond 1 is the west basin, which was described earlier. It would fill and spill over into Pond 2 (east basin) 

after about 6 years of project operation. Pond 2 would need an additionql 

3 years to fill, at which time, the two ponds would merge into Pond 3.11 

After <:.bout 30 years of project operation, the pond would have sufficient 

surfaCE! area so that the average annual evaporation would exceed the average annual inflow. From about the 75th year to the lOOth year, the 

pond would consist of only precipitated salt during some months of each 

year. Based on a constant 5 cfs inflow, the pond would have its entire 

inact~re storage capacity (68,100 acre-feet) fill~d with precipitated 

salt a::ter 100 years. 

After 100 years of operation, the brine inflow would be discontinued. 

Because the total capacity of the reservoir would be 86,800 acre-feet, 

18,760 acre-feet of capacity would be available fQr annual natural inflows. The design annual natural inflow of 22,200 acre-feet ~auld be 

stored with a total evapora~ion duririg thai year of 3,500 ~cie-feet~ The 

average annual natural inflow would increase throughout the life of the 

unit as the surface area and, hence, the rain on the pond surface increased (100 percent of the rain on the pond surface is considered as 

naturc::.l runoff, whereas only about 10 percent of the rain on the surrounding bc.sin would make it to the pond because of evapotranspiration). After

CHAPTER IV UNIT PLAN AND DESIGN 

100 years, the average annual inflow would be approximately 3,600 acrefeet, compared to an average evaporation potential of about 8,000 acrefeet. 

For safety purposes, a 50-cfs spillway would be provided at the top 

of the flood control pool, which, along with a 1.8-foot surcharge with a 

capacity of 6,540 acre-feet, would be sufficient to pass the inflow design flood. It is not anticipated that this spillway would ever have to 

be used because of the flood storage capacity that would be available after the 100-year life •

CHAPTER V 

INVESTIGATIONS 

Feasibility investigations were initiated in 1971 to study control 

methods of preventing salt from entering the Dolores River. After gathering available information from literature, maps, and drill logs, a resistivity survey was conducted along the river in April 1972 to locate 

subsurface anomalies for guidance in planning initial exploratory drilling. Unfortunately, the area surveyed contained a brine layer of very 

low resistance at a depth of about 10 feet which prevented penetration 

of the electric current. There were also lateral changes in resistivity, 

which produced irregular curves, making interpretation difficult. Information deduced from the soundings, however, was used to confine the exploratory drilling to the expected problem area. A copy of the resistivity survey is on file in the Durango Office. 

Surface Water 

As described in Chapter II, stream gaging and water quality sampling 

stations were established in 1971 at three locations--the Dolores River 

at Bedrock,Colo,; the Dolores River near Bedrock, Colo.; and West Paradox 

Creek above Bedrock, Colo. In addition, as discussed in Chapter III, 

five electrical conductivity meters were placed above, in, and below the 

.area of emerging brine to continuously record changes in salinity. 

Exploratory Drilling 

Based on information obtained from field surveys, the resistivity 

survey, and a study of existing well logs, a drilling program was initiated. The locations of the wells discussed in the following section can 

be seen on the location map in Chapter I. During the summer of 1972, 

five core holes (DH lPX-DH 5PX) located along the eastern limit of the 

river meander course were drilled using NX-sized (3-inch) core drilling 

equipment. Depths ranged from 74 feet to 200 feet and extended into consolidated portions of the valley fill. The core holes yielded information confirming shallow overburden, a shallow saline water table, and a 

brecciated gypsiferous formation below the overburden (see logs in the 

Attachment Section). 

A more comprehensive exploratory drilling program was accomplished 

in late 1972 and included holes on both sides of the river. Twelve holes 

(numbered DH-CX) were drilled usi.ng a 6-inch rotary drill ranging in depth 

from 69 feet to 240 feet. Data obtained from this drilling .included 

drillers' logs, material samples, drill fluid samples, and readings of 

77

CHAPTER V INVESTIGATIONS 

natural salinity and hydrogen sulfide gas, Perforated casings were installed in all drill holes for future water level readings and chemical 

sampling. 

Information obtained from this drilling indicated a freshwater zone 

near the river from 1 to 20 feet below the ground surface extending to a 

maximum depth of about 100 feet to the west of the river. The major freshwater zone overlies brine in the valley fill along the west side of the 

river and is wedge shaped with the maximum thickness upriver and to the 

west along West Paradox Creek and tapering toward the river, The river 

deposits on the east side of the river are variable, but generally shallow, and contain only small amounts of freshwater overlying brine, In 

the river channel, the brine interface surfaces sharply about midvalley. 

In January 19j3, three core holes were drilled into brine producing 

aquifers (DH 6PX, DH 7PX, and DH BPX) and a test well (DH 23CX-Test W~ll 

No. 1) to test the aquifers. The core holes were drilled with NX core 

drilling equipment. DH 7PX was drilled to a depth of 470 feet, DH 6PX to 

a depth of 192 feet, and DH BPX to only 85 feet. Two piezometers and a 

water table observation pipe were installed in DH 6PX and DH 7PX with the 

piezometers measuring piezometric head at different levels. Because of 

flooding during the drilling operation, work on DH BPX was stopped prematurely. The NX drill casing was left in DH 8PX and only the piezometric 

head of the zone at 84 to 85 feet can be measured. A water level recorder 

was placed over the pipe at DH 8PX to record water level changes, and a 

water table observation well was placed near DH 8PX. 

Test Wells 

As discussed in Chapter IV, in 1973 Test Well No. 1 was drilled to 

a total depth of 300 feet, Test Wells 2 and 3 were drilled in 1975 into 

the residual gypsum cap, and 18 test wells were drilled in the summer of 

1977. 

Observation Wells 

Based upon data obtained from the initial drilling and the geological investigation, a ground water observation network described in Chapter IV was designed with lines of piezometers parallel and perpendicular 

to the river. The ground water observation network was installed during 

the summer and fall of 1975 and included piezometers at 27 sites. The 

sites were numbered 1Wl-2C4 on the west side and from 2El through lOEl on 

the east side. A 6-inch hole was first drilled to the top of the gypsum 

and then a 4~-inch hole was continued to a maximum depth of 225 feet. 

Problems prevented drilling to the desired depth in two holes. Piezometers were installed in each hole with one tip placed at the bottom of the 

hole and a second tip placed just above the gypsum cap in the course

CHAPTER V INVESTIGATIONS 

gravel zone, A water table observation pipe to a depth of 25 feet was 

also placed at each site. 

Pilot Holes 

In October 1976, 18 pilot holes were drilled using a hammer drill at 

proposed test well sites, Locations can be seen on the Investigations 

Map on page 13. Data obtained from this drilling include the following. 

1. Depth to water 

2. Approximate depth to the freshwater-brine interface 

3. Samples of aquifer material for mechanical analysis 

4. Approximate locations of permeable brine producing aquifers 

5. Depth to top of salt cap (gypsum breccia) 

6. Samples of the brine encountered 

These pilot holes were used in the design of the 18 production wells. 

Only 16 of the sites, however, were later used for production well sites. 

Test wells 23A and 2ClA are the two additional wells. The locations are 

shown on the General Investigations Map on page 13 . 

Evaporation Study and Weather Stations 

To evaluate evaporation and other climatological parameters in the 

project area, two weather stations were established, one near Bedrock, 

Colo., and one in Dry Creek Basin. The stations were put into operation 

in January 1975 and are still functioning. The following tabulation 

lists the equipment in operation at each station.

CHAPTER V INVESTIGATIONS 

At both stations daily minimum and maximum temperatures are read 

from a minimum-maximum thermometer. At the Dry Creek Basin station, the 

temperatures are checked with readings obtained from a hygrothermograph 

chart which is changed weekly. 

Relative humidity is measured daily at each station by using a sling 

Psychrometer. At the Dry Creek Basin station, these readings are compared and correlated with the reading obtained from the hygrothermograph. 

A weighting-type recording rain gage is set up at both weather stations. Charts on these gages are changed weekly. A wedge-type nonrecording rain gage is also set up at each station. These gages are read 

daily and are used to check the accuracy of the recording gages. 

Anemometers are mounted on the northwest corner of the evaporation 

pan platforms so that the vanes are 0.25 foot above the evaporation pans. 

Daily readings of elapsed cumulative nautical miles are recorded daily. 

The evaporation pans at the weather stations are the standard size 

Class "A" land pans set on platforms to allow free air circulation under 

them. Minimum and maximum temperatures of the water in the evaporation 

pans are obtained daily by using minimum-maximum mercury thermometers in 

the pans. The water level in the pans is read daily using a stilling 

well, which remains in the pan, and a hook gage. \-lith accurate observation the water level can be read to the nearest hundredth of an inch. 

In order to measure brine evaporation rates, one pan in Dry Creek 

Basin was initially filled with brine pumped from Test Well No. 1 in Paradox Valley. After the initial filling, freshwater was added when needed 

in an attempt to keep the brine pan filled and at nearly the same concentration. During the high evaporation months, there was some precipitation 

of salt in the brine pan; however, this salt went back into solution when 

freshwater was added and the contents of the pan were mixed. Summaries 

of the weather station data are included in the attachments. 

Results from an evaporation study at the two weather stations for the 

2 years have shown an average freshwater pan evaporation rate of 65 inches 

at the Bedrock station and 55 inches for the Dry Creek Basin station. The 

average evaporation rate for a pan located at the Dry Creek Basin station 

containing brine (23 percent salt) was 53 inches. There are significant 

seasonal variations, with about 48 percent of the evaporation occurring 

during June through August and 85 percent occurring during April through 

October. 

As more data become available, the weather station information will 

provide an increasingly accurate estimate of evaporation and other climatological parameters. This information will be very useful during t:1e 

design data collection program to help in the final sizing of unit facilities and during unit operation to closely monitor evaporation at Radium

A bulking factor is used to take into account increased volume when 

the precipitated salt is in hydrated form. For Paradox Valley brine, 

less than 5 percent of the salts fits into this category and, for this 

reason, a bulking factor of 1 was selected • 

Brine inflow (acre-feet).--The input for pumped brine is in cfs. 

The brine inflow to Pond 2 is that amount which overflows Pond 1. The 

salt content of the brine inflow to Pond 2 is the same as the salt content of Pond 1 during that month. 

Natural runoff (acre-feet).--Natural runoff is the volume of rain 

that falls directly on the reservoir surface plus the volume of runoff 

from the rain on the drainage area. The runoff is calculated from a correlation between monthly rainfall records at Norwood, Colo., versus the 

monthly flow volumes at Dry Creek.l/ This correlation can be expressed 

by these empirical equations: 

where log 10 (runoff)

and runoff

= 4~97 inches 

Thirty-two years of precipitation records at Norwood, Colo., and 2 

years of records at Dry Creek Basin were available. For these 2 years 

(1975 and 1976) the precipitation in Dry Creek Basin was 70, percent of 

that at Norwood. This proportion was used to generate 32 years of record 

for Dry Creek Basin and then used in a cyclic manner to generate 100 

years of precipitation data for the operation study.

Total inflow (acre-feet),--The total inflow is the sum of the brine 

inflow and the natural runoff for each month~ 

Evaporation (acre-feet),--The evaporation for any month is the product ,Jf the monthly evaporation from a freshwater reservoir, Adam•s evaporati~Jn coefficient,]) and the average reservoir surface area for that 

month. The monthly evaporation from a freshwater reservoir is calculated 

from data provided by the weather station at Montrose. The freshwater pan 

to freshwater reservoir evaporation ratio of 0.70 was used to arrive at 

the 40.8 inches of evaporation from a freshwater reservoir. Adam's evaporation coefficient, 100.29 - [1~005 x (percent salt - 100)] ranging between 

1 and 0.71, adjusts the evaporation rate for varying salt concentrations 

in the brine. The evaporation column includes all volumes that leave solution, which is ~he volume of water that evaporates plus the volume the 

precipitated salt occupied while in solution. 

End-of-month content (acre-feet).--The end-of-month (eom) content 

equa.ls the previous month's eom content, plus the total inflow, minus the 

evaforation, plus the month's salt precipitate. The annual sediment deposition of 24 acre-feet a year is added to the eom content each December. 

Wher. both Pond 1 and Pond 2 are receiving inflow, the sediment is equally 

div:i.ded between them. In the case where Pond 1 is overflowing to Pond 2, 

the overflow is subtracted from the end-of-month content of Pond 1. 

End-of-month surface area (acres).--The end-of-month surface area is 

comfuted from the end-of-month content by interpolating between areacapc.city data pairs that are input to the program. 

Content as a percent of capacity (percent).--The end-of-month content 

is d.ivided by the capacity of the pond under consideration to find the percent of contents in the pond. 

Concentration of salt in solution (ppm).--The ppm is calculated for~ 

thre:e separate cases. , The f1-rst case is the most connnon. Whenever there 

is a. brine so~ution, the ppm/ is the weight of ~otal dissolved salts.._.di..,~ · . 

vide:d by the \veight of· solution... Case 2 occurs when the weight of s'olu~ 

tior. is zero, that is, when the solution has evaporated and only precipitate:d salt remains in the reservoir. For this case, the ppm is set at 

the saturation level to eliminate any discontinuity. The final case occurs when Pond 2 has no solution from the month before and only natural 

runc,ff for the present month's inflow. The ppm is set at 1,000,. Salt· 

will. precipitate out of solution at 292,000 ppm so the salt concentration 

will never exceed 29.2 percent. 

Month's salt precipitate (acre-feet).--The amount of salt that settleE out each month is the total precipitated salt in the reservoir minus

the total precipitated salt in the reservoir from the month before. Windblown or runoff sediment is never included in this calculation. 

Total salt precipitate (acre-feet).--The total weight of salt precipitate in the reservoir is found by subtracting the total weight of salt that 

can remain in solution at saturation for that month from the total weight 

of salt in the reservoir. The volume of the precipitated salt is found by 

dividing its weight by 1.436 (the specific gravity of precipitated salt) 

and by 1,359 (the tons per acre-foot conversion factor) then multiplying 

by 1 (the bulking factor). Sediment is added to the total salt precipitate 

each December. If two ponds are in operation, the sediment is divided 

equally between them. Once the salt precipitates, it is assumed_ it will 

not return to solution. Therefore, the total salt precipitate will never 

be less than the month before. 

Salt precipitate as a percentage of reservoir capacity.--The percentage of salt precipitate in the reservoir is calculated by dividing the 

volume of the precipitated salt ~by the maximum capacity of the pond being 

considered .
