The 1972 Survey of Glendo Reservoir

GENERAL INFORMATION

Location and Ownership

Glendo Reservoir is in Converse

dam is on the North Platte River

Wyoming. The dam and reservoir

of Reclamation, U.S. Department

and Platte Counties of Wyoming. The

about 4.5 miles southeast of Glendo,

are owned and operated by the Bureau

of the Interior.

Description of the Darn

Glendo Dam (fig. 1) is an earthfill structure 190 feet high and

2,096 feet long. About 2,400 feet of dikes are required across a

low area on the south side of the reservoir 1.5 miles west of the

dam. An uncontrolled concrete spiliway 45 feet wide is located about

450 feet north of the right abutment of the dam.

The power system consists of a two-unit plant having a rated head

of about 100 feet. The installed capacity is 24 megawatts.

Description of the Reservoir

The original (1957) capacity of Glendo Reservoir (fig. 2) was

797,018 acre-feet at water surface elevation 4653 feet (uncontrolled

spillway crest). The capacity in 1972 was 789,402 acre-feet at this

elevation indicating a loss of 7,616 acre-feet since the dam was

originally built. The length of the reservoir is about 14 miles.

Drainage Area Description

The net sediment contributing area above Glendo Reservoir is

4,190 square miles. This is determined by adjusting the total

drainage area of 19,504 square miles above the reservoir as

follows:

Drainage Noncontributing

Station area (mi2) area (mi2)

Glendo 19,504 5,174

Alcova* 14,771 4,659

Difference 4,733 515

contributing area = 4,733 -515 _28** = 4,190 mi2

* North Platte River at Alcova Dam (closed for operation in 1938)

** Reservoir surface area in mi2 at el 4653 ft (uncontrolled

spillway crest)
The oldest rocks of the region form the erosion-resistant mountain

cores and consist largely of pre-Cambrian granite with associated

gneiss and schist. Paleozoic sediments, principally hard limestone,

f lank the granite mountain heights in steeply dipping beds. Mesozoic

rocks are exposed in large areas of lower elevation west of Casper,

between Casper and Douglas, and in the Laramie River Basin. Most of

the sediments are thick shales with smaller amounts of sandstone,

limestone, and coal.

The soils vary widely in nature even within relatively small portions

of the basin. Generally, they are shallow and immature because of

the arid climate and wind and water erosion. Except for the relatively small area of alluvial deposits, the soils are closely associated with the geology of the region.

Hydrographic Records

Streamf low records for the North Platte River at Orin, Wyoming, were

used to estimate the inflow to Glendo Reservoir which showed an

average of 1,077,220 acre-feet/yr, for 16 years of record (1958-73).

Based on this same period, the average annual discharge of the North

Platte River below Glendo Reservoir was 1,107,900 acre-feet, an

indication of the outflow.

Figure 3 is a graph of the pool-duration curve showing the percent

of time that pool elevations were equalled or exceeded.

SURVEY INFORMATION

This is the first survey of Glendo Reservoir since the dam was closed

in 1957.

Surveying Methods

Initial fieldwork consisted of locating 68 of the reservoir sediment

range ends that had been permanently rnonumented during the original

survey. Standard land surveying procedures and equipment were used

to run the levels on each range line above water. For ranges that

were partly underwater, levels were run from the monuments to water's

edge on each side of the reservoir. Temporary stations were established at the edge of the water to facilitate horizontal control.

The hydrographic survey was run in September, October, and November

1972, using sonic depth recording equipment to sound the submerged

portions of the ranges. The sonic equipment was installed on the

deck of a pontoon boat. First, the boat was positioned on a range

line as near to the shore as possible. Then the line was profiled

from the temporary station established on the water's edge to the

2
center point of the transducer using a chain to measure horizontal

distances and a level rod to measure depths. The depth recorder was

turned on and the boat propelled across the range to profile the

remaining portion of the range line underwater. A man on shore kept

the boat on line through radio communication with the boat operator.

A distance measuring machine was used to measure horizontal distances

across the reservoir. The machine provided a means of marking the

"fix" lines on the sonar chart. Upon reaching the other end of the

range line, the process of profiling the line from the transducer

centerline to the end at the temporary station was repeated as in

the beginning. When this was completed, the man on the opposite

shore was told to release the wire of the distance measuring machine

and a gasoline-powered engine was used to reel it back in.

Water surface elevations of the reservoir at the end of each range

line were measured using a hand level and rod at the beginning and

ending of the sounding run. The water surface elevations then provide the bases for transcribing the sonar charts.

RESERVOIR SEDIMENT DISTRIBUTION

The longitudinal thalweg profiles in figure 4 show how sediments

were distributed in the reservoir. The thalweg elevation or lowest

point of the range line was used to plot the profiles for the 1957

and 1972 conditions.

The greatest depths of sediment deposits occurred between 6 and

14 miles above the dam. Maximum depth of about 10 feet was deposited

between ranges 9 and 10. An average of about 0.3 foot of sediment

was deposited between 15 and 19 miles above the dam. The profiles

showed slight degradation in the reach between ranges 24 and 26.

Table 1 summarizes the area, capacity, and sediment data for Glendo

Reservoir based on the 1972 survey results. Total sediments that

accumulated in the reservoir were 7,616 acre-feet since 1957 (see

table 1, column 12).

A graph of the depth-capacity (fig. 5) relation using the original

(1957) data indicated the reservoir to be a flood plain-foothill,

Type II as classified.* The sediment disposition curves in figure 6

show the actual sediment distribution (1972 survey data) compared

with the one from the Type II computations. The curves show the

percent depth against the percent sediment. Examining the curves

* See "Design of Small Dams," Second edition, Revised Reprint, 1974,

p. 781, U.S. Department of the Interior, Bureau of Reclamation.

discloses that, for the most part, the sediment was actually distributed at lesser quantities than indicated by a Type II. This might

be partially due to the small quantity of sediment that has heretofore

accumulated. Other factors influencing this actual sediment distribution would include the type of reservoir operation and the size

and texture of the inf lowing sediments.

Profiles of 13 reservoir sedimentation ranges surveyed in 1972 and

1957 are shown in figures 7 through 19 to represent typical laterally

distributed sediments in the reservoir.

SEDIMENT ANALYSES

Sediment Accumulations

A total volume of 7,616 acre-feet of sediments has accumulated in

Glendo Reservoir since the darn was completed over 14 years ago. An

average annual accumulation rate of 524 acre-feet was computed for

the 14-year period.

Reservoir Sedimentation Summary

Table 2 summarizes the reservoir sediment data as of the May 1972

survey. The data include a tabulation of the sediment accumulation

information mentioned in the previous section. A sediment yield

rate of 0.13 acre-foot/mi2/yr was computed from the 1972 survey data.

Since sediment samples were not collected during the survey, information on the unit weight or particle size analyses of the deposited

sediments was not available. A unit weight of 70 lb/ft3 was assumed

to compute the sediment deposition of 198 tons/mi2/yr.

DEGRAI)ATION BELOW DAN

A system of six degradation ranges (fig. 20) was established below

Glendo Dam. The ranges were originally surveyed in 1957 and resurveyed in 1972. The profiles of five of these ranges are shown in

figures 21 through 25.

The profiles show negligible degradation at range 2; however, degradation occurred at the remaining ranges in the following amounts:

Average Degradation

Range No. (ft)

3 4

4 5.6

5 1.3

6 5.3

4
Based on these observations, the channel regime of the North Platte

River, below Glendo Dam has undergone some degradation. From the

preceding tabluation a degradation depth of greater than 5 feet is

indicated at range 6, which is about 10 miles below the dam.

RESERVOIR AREA AND CAPACITY

The 1972 Glendo Reservoir surface areas were determined by using

reservoir sedimentation range width ratios. Briefly, this method

entailed comparing the 1972 range widths with the 1957 widths. The

ratio, 1972 width/1957 width is used in the computations. The computations are simplified by subdividing the reservoir into segments

using the sedimentation range lines as segmental boundaries. The

1957 reservoir topographic maps were planimetered to obtain the

surface areas at 10-foot contour intervals. Significant changes

were noted in the replanimetered results of these original areas,

particularly for elevations from 4510 through 4540 feet (see table 1,

columns 2 and 3). These differences were apparently due, in part,

to the the borrow areas which were excavated after the 1957 reservoir

areas were planimetered. Adjustments to the areas were made to

account for these changes (see table 1, column 6). Because the

areas at elevation 4550 feet and above (table 1, column 3) were replanimetered within the prescribed limit of practical accuracy (less

than 3 percent), the original areas (column 2) were used for this

upper range and tabulated in column 6.

The 1972 surface areas were the control parameters for computing the

reservoir capacities by electronic computer. The program was written

to compute areas at 1-foot increments by linear interpolation between

the 10-foot contour intervals. Respective capacities and capacity

equations were then obtained by integration of the area equations.

The resulting capacity equations are of a second order polynomial

form,

y = a1 + a2x + a3x2

where:

y = capacity

x = distance above an elevation base

a1 = intercept

a2 = coefficient

a3 = coefficient

Results of the 1972 Glendo Reservoir area and capacity computations

are listed in table 1, columns 9 and 10. Listed in columns 6 and 8

of the table are adjusted values of the original areas and capacities

5
for comparison with the 1972 values. The 1972 area and capacity

curves are shown in figure 26. The original area and capacity curves

were not included in this figure because the differences in values

between surveys were too small to be made discernible. At the uncontrollable spillway crest elevation of 4653 feet, the present capacity

of Glendo Reservoir is 789,402 acre-feet and the surface area is

17,986 acres.

SUMMARY AND CONCLUSIONS

The 1972 sediment survey report of Glendo Reservoir includes a discussion of the methods used to measure and study the 14.5 years of

sediment accumulation in the reservoir. Also, the field surveying

equipment is briefly described. The survey was run primarily to

collect the data necessary for computing the present capacity of

Glendo Reservoir.

Standard land surveying methods were used to run levels from the

permanent range end monuments to stations temporarily established

at the reservoir water's edge. Sonic depth recording equipment

mounted on a boat was used to run the hydrographic survey. This

system continuously recorded reservoir depths as the boat was propelled across the range line. Five men were needed to run the hydrographic survey. A distance measuring machine was used to maintain

horizontal control across the range line.

Water surface elevations at each range line were measured with a

hand level at the beginning and ending of the sounding run.

The greatest depths of sediment deposits occurred in the reservoir

between 6 and 14 miles above the dam with the maximum depth of about

10 feet deposited between ranges 9 and 10.

Analyses of the reservoir sediment data collected during the 1972

survey indicated a total sediment inflow volume of 7,616 acre-feet

at elevation 4653 feet (uncontrolled spillway crest) since the dam

was closed in 1957. This indicates a loss in reservoir capacity of

less than 1 percent. The average annual sediment accumulation rate

of 524 acre-feet and the sediment yield rate of 0.13 acre-foot/mi2/yr

were noted during the 1957 to 1972 period. Degradation below the

dam varied from 1 foot to greater than 5 feet as observed at four

downstream ranges.

The capacity of Glendo Reservoir, as determined from the 1972 survey,

is 789,402 acre-feet and the surface area is 17,986 acres at the uncontrollable spillway crest elevation of 4653 feet. The 1972 reservoir

surface areas were computed by the width ratio method. Both reservoir area and capacity data were compiled at 1-foot intervals using

electronic computer facilities.

CONVERSION FACTORS--BRITISH TO 1ETRIC UNITS OF MEASUREMENT

The following conversion factors adopted by the Bureau of Reclamation are those published by the American

Society for Testing arid Materials (ASTM Metric Practice Guide, E 380-68) except that additional factors )°)

commonly used in the Bureau have been added. Further discussion of definitions of quantities and units is given in

the ASTM Metric Practice Guide.

The metric units and conversion factors adopted by the ASTM are based on the "International System of Units"

(designated SI for Systeme International d'Unites(, fixed by the International Committee for Weights and

Measures; this system is also known as the Giorgi or MKSA (meter-kilogram (mass(-second-ampere) system. This

system has been adopted by the International Organization for Standardization in ISO Recommendation R-31.

The metric technical unit of force is the kilogram-force; this is the force which, when applied to a body having a

mass of 1 kg, gives it an acceleration of 9.80665 m/sec/sec, the standard acceleration of free fall toward the earth's

center for sea level at 45 deg latitude. The metric unit of force in SI units is the newton (N), which is defined as

that force which, when applied to a body having a mass of 1 kg, gives it an acceleration of 1 m/sec/sec. These units

must be distinguished from the (inconstant) local weight of a body having a maw of 1 kg, that is, the weight of a

body is that force with which a body is attracted to the earth and is equal to the mass of a body multiplied by the

acceleration due to gravity. However, because it is general practice to use 'pound" rather than the technically

correct term "pound-force," the term "kilogram" (or derived mass unit) has been used in this guide instead of

"kilogram-force" in expressing the conversion factors for forces. The newton Unit of force will find increasing use,

and is essential in SI units.

Where approximate or nominal English units are used to express a value or range of values, the converted metric

units in parentheses are also approximate or nominal. Where precise English units are used, the converted metric

units are expressed as equally significant values.
