INTRODUCTION

Elephant Butte Dam (originally called Engle Dam) was one of the first major

structures built by the Reclamation Service (now the Bureau of Reclamation)

after its formation in 1902. Construction of the dam began in 1908, but

progress was delayed when difficulty was encountered in obtaining reservoir

land. Construction of the dam resumed in 1912 and was completed in 1916,

although water storage operations began in January 1915. Located about

125 miles north of El Paso, Texas, on the Rio Grande, the dam is part of the

multipurpose Rio Grande Project that controls floods, generates power, and

stores and delivers irrigation water.

The dam is a 301-foot-high concrete gravity structure that is 1,674 feet long

and impounds 2,110,298 acre-feet of water. The spillway is an uncontrolled

concrete ogee weir structure. A spillway channel below the dam was added in

1921 and modified in 1947. Service outlet deflectors were added in 1944.

The general plan and sections of the dam and spillway are shown in

figure 1 1/.

In 1915, the surface area of Elephant Butte Reservoir was 40,064 acres

and the capacity was 2,634,800 acre-feet at a spillway crest elevation of

4,407 feet 2/. The 1980 survey showed a surface area of 36,897 acres and a

capacity of 2,110,298 acre-feet at the same spillway crest elevation. This

difference indicates a loss of 524,502 acre-feet in capacity in the 65.1

years since the dam was built.

The reservoir has a length of 41 miles and an average width of 1.39 miles.

The average width was determined for the entire reservoir including the

portion known as "The Narrows" which separates the upper and lower reservoir

areas.

The total Rio Grande drainage area above the dam is 25,923 square miles, of

which 11,803 square miles are the net sediment contributing area. Sediment

from the remaining drainage area is being trapped by upstream dams such as

Abiquiu, which closed in 1963; Galisteo, closed in 1970; and Cochiti, closed

in 1973.

A plot of monthly inflows to the reservoir is shown in figure 2 for the

period January 1916 through June 1980. The average annual inflow, based on

63.3 years of record, is 845,300 acre-feet. An inflow-duration curve based

on the monthly inflow discharge is shown on figure 3. Information from

curves of this type is useful in making reservoir operation studies. Streamflow records of the gaging station at San Marcial, New Mexico, were used to

represent the inflow for the period through water year 1951. Beginning with

water year 1952, the combined streamflow records of the floodway and conveyance channel at San Marcial were used. These records, however, did not

reflect the total inflow since additional downstream tributaries to the

reservoir, such as Monticello and Nogal Canyons, also contribute to the

inflow.

1/ All figures and tables follow the text.

2/ All elevations quoted are based on the original project datum. To adjust

the elevations to mean sea level datum, 43.3 feet should be added.
Monthly outflow records were plotted on figure 4 for the period October

1916 through September 1980 (63.9 years). An average annual outflow of

701,400 acre-feet was computed for this period.

Reservoir stages at the end of each month from March 1915 through January

1980 are plotted on figure 5. Elephant Butte Reservoir operation ranged from

a minimum elevation of 4,258.03 feet in 1954 to a maximum elevation of

4,409.15 feet in 1942.

SUMMARY AND CONCLUSIONS

This report includes a discussion of methods used to measure and study

65.1 years of reservoir sediment accumulatiofts. It also briefly describes

the field surveying procedures and equipment.

The primary purpose of running the 1980 survey was to gather data needed to

compute the capacity of Elephant Butte Reservoir as required by the Rio

Grande Compact.

Standard land surveying methods were used to establish horizontal control

points for the survey. The hydrographic survey used sonic depth recording

equipment and an automated survey system with a line-of-sight electronic

positioning unit. The system continuously recorded reservoir depths and

horizontal distances from a fixed point as the boat was steered across the

range line. Reservoir water surface elevations read on the gage at the dam

were used as control in converting sonic depth measurements to true bottom

elevations and to delineate the cross-sectional profiles.

The capacity of the reservoir from the 1980 survey was determined to be

2,110,298 acre-feet, with a surface area of 36,897 acres at a spillway

crest elevation of 4,407 feet. The reservoir area and capacity tables were

produced by a computer program which used measured contour surface areas and

a curve-fitting technique to compute both area and capacity at prescribed

elevation increments.

A comprehensive summary of the reservoir sediment data for the 1980 survey is

contained in table 2. The volume of sediments that have accumulated in the

reservoir since the original survey amounted to 524,502 acre-feet, indicating

a loss in capacity of about 20 percent. An average annual sediment accumulation rate of 8,057 acre-feet was found for the period from 1916 to 1980. The

sediment yield rate from the drainage area was 0.311 acre-foot per square

mile per year for the same period.

DESCRIPTION OF BASIN

Topography of the drainage area is varied. In the extreme northern portion,

it is mountainous and rugged. South of Santa Fe, New Mexico, the topography

is less rugged, consisting of isolated mountains separated by desert plains

and the Rio Grande Valley. The elevations of the drainage area vary from

12,000 feet above mean sea level at the Continental Divide to 4,450 feet

above mean sea level in the reservoir headwaters area.

2
The higher elevations are forested with pine and fir trees, and the slopes

are sprinkled with cedars along the foothills. Natural cover of the plains

consists chiefly of creosote bush, sagebrush, greasewood, cactus, and natural

grasses. Thick stands of salt cedars, willows, and cottonwoods grow along

the riverbanks above the reservoir.

The Rio Grande begins in the San Juan Mountains of Colorado and flows between

the Conejos Mountains and La Garita Hills. Stream channel slopes are steep

in the mountainous headwater regions. Most of the surface rock in these

regions is igneous or metamorphic and not easily eroded. Just above the

New Mexico State line, the river enters a deep canyon flowing through a

stretch of low sediment contribution until it enters Espanola Valley near the

confluence with the Rio Chama. Upon leaving the valley, it enters White Rock

Canyon in the vicinity of Otow Bridge. The unconsolidated sediments of the

Santa Fe Formation (Miocene and Pliocene continental deposits) have been

eroded to form the valley of the Rio Grande from the lower end of White Rock

Canyon near Cochiti Diversion Dam to near San Acacia. The flood plains and

terraces of the valley are composed of alluvium that is available for transport and contributes substantial quantities of sediment to the Rio Grande.

From the mouth of the Rio Salado, just upstream from San Acacia, to the headwaters of Elephant Butte Reservoir, the Palomas Formation of the Quaternary

period has been eroded to form the river valley. The major geologic formations of the Rio Grande Valley are of the Cenozoic era.

SURVEYS AND EQUIPMENT

Nine different surveys were conducted previously, beginning in 1916. The

1925, 1935, 1940, and 1957 surveys were run by the contour method, while the

range method was used for the 1947, 1969, 1974, and 1980 surveys. Fieldwork

for the 1980 survey began in June 1979 and ended January 24, 1980. A layout

of the reservoir sedimentation range system is shown in figure 6.

Surveyinq Methods

The fieldwork consisted of locating the existing sedimentation range end

markers and relocating those which had been lost or destroyed. To prepare

for the range line survey, an extensive line clearing progrn was conducted

in the reservoir area above the Narrows. Range lines 41 through 61 and

portions of 40, 37, and 36 were not cleared because of high ground water or

surface water. To develop range end control for the 1980 hydrographic

survey, a traverse was surveyed from Range 85 through Range 50 and tied

into a triangulation point at Range 38 west. Precise electronic distance

measuring equipment that could be interfaced with a digital computer to

process the data was used for this traverse work. Control points established

by the traverse facilitated the profiling of inundated ranges by the sonic

sounding equipment described in the following paragraph. Results of the old

traverse established for previous surveys were used for control points in

running the 1980 survey for ranges in the reservoir area upstream from Range

50. The above water portion of most existing range lines was profiled from

the range end to water's edge using standard land surveying procedures and

equipment.

3
A hydrographic survey was run in January 1980, using sonic depth recording

equipment to sound the underwater portion of 45 range lines. A depth

recorder was interfaced with an automated positioning system (fig. 7) to

give continuous reservoir depth and sounding position as the sounding boat

traversed each range line. The positioning system transmitted a line-ofsight, microwave signal to fixed shore stations (fig. 8), and converted

the time of reply to range distances, which were then used to compute the

coordinate position of the sounding boat. The controls required for the

system included reservoir elevation, horizontal grid coordinates for all

range ends and fixed shore stations, and the elevations of the shore station

antenna. Upon activating the system, the boat (fig. 9) was steered across

the range line at a velocity of 8 feet per second. The system also gave

directions to the boat operator for maintaining course. During each run, the

depth and position data were recorded on magnetic tape for later processing

on an electronic computer. A graph plotter was used to track the boat and to

give an immediate plot of each range profile. Auxiliary field equipment

included radios for communication between shore and boat personnel and

another boat to move equipment and personnel around the reservoir.

A "cutting in" or triangulation procedure was used to resurvey 15 ranges in

the area beginning with Range 60 on upstream through the Narrows.

RESERVOIR SEDIMENT DISTRIBUTION

Lonqitudinal Distribution

The longitudinal profiles were plotted for the original, 1969, and 1980

reservoir conditions (fig. 10). Longitudinal profile data were also plotted

in dimensionless form (fig. 11) for the original and 1980 conditions relating

percent of depth to percent of distance. Percent of depth was computed as

the ratio of the thaiweg depth at each range to the total depth. Thaiweg

depth was computed as a difference between the thalweg elevation (lowest

point) at a section and the lowest point on the profile (elevation 4,210).

Total depth, 197 feet, was taken as the difference in lowest point on the

profile (elevation 4,210) and the spiliway crest elevation 4,407. Percent of

distance was computed as a ratio of the distance between the dam and each

range to the total distance 41.33 miles measured between the dam and the

point where the longitudinal profile intersects the thaiweg elevation 4,407

upstream. The graph on figure 10 indicates that between the 1915 and 1980

surveys, sediments had deposited longitudinally to depths shown below:

The greatest depths of longitudinal sediment deposits occurred between 14 and

16 miles above the dam. This reflects a morphological effect that the

Narrows region has on sediment deposition. The Narrows has an average width

of 0.36 mile compared to the average width of 1.39 miles for the total

reservoir.

As a matter of further practical interest, a theoretical distribution of

sediment within the reservoir was computed using the Empirical Area-Reduction

Method [1]*. It was assumed that the sediment inflow volume to be distributed would be 524,502 acre-feet, the volume measured by the 1980 survey. A

plotting of the depth-capacity relationship (fig. 12) using the original data

indicated the reservoir to be type II. Results of the sediment distribution

computations are listed in columns (8), (9), and (10) of table 1 for a type

II reservoir. These computations predicted the sediment would reach an

elevation of 4,259.4 feet by 1980. This estimate compares favorably to the

elevation of 4,234 feet determined from the 1980 survey. The sediment

distribution curves on figure 13 show how the actual distribution compares

with the theroretical distribution of a type II reservoir. The curves show

percentages of depth plotted against sediment deposited. The greatest

differences between the actual and type II curves are in the 60 to 80 percent

depths.

Using the end-of-month data (fig. 5), a stage-duration curve (fig. 14) was

derived. This type of curve has a twofold use: (1) classifying the reservoir for sediment distribution computations, and (2) predicting the delta

formation of a reservoir [1]. For delta computations, data from the curve

are used to determine the pivot point (where the topset and foreset beds

intersect). Using the 50 percent duration as a mean, the curve shows an

end-of-month elevation stage of 4,337 feet. This indicates the pivot point

occurs at Range 60 as seen in the longitudinal profile (fig. 10). For a

sediment distribution study, the end-of-month stage of 4,337 feet indicates

the reservoir is operated with a normally moderate to considerable reservoir

drawdown. This would classify the reservoir as a type II (flood plainfoothill) reservoir as indicated by the depth-capacity curve (fig. 12).

Lateral Distribution

Ground profiles of the 75 reservoir sedimentation ranges are shown on figures

15 through 89. The profiles illustrate the general lateral distribution of

sediments in the reservoir.

The orignal and 1980 profiles do not fully agree in the lateral direction for

all ranges. The original profiles were transcribed from a 1915 topographic

map with a contour interval of 10 feet. Thus, the point locations from the

1980 survey were of much higher accuracy than the location of points read

from the 1915 topographic map. Also, it was necessary to estimate a portion

near the end of some profiles to show how the original survey data connect

with the 1980 data and to facilitate the reservoir area computations.

SEDIMENT ANALYSES

Sediment Accumulation

Sediments have accumulated in Elephant Butte Reservoir to a total volume of

524,502 acre-feet since the dam was constructed over 65 years ago. An

average annual accumulation rate of 8,057 acre-feet was computed for the

65.1-year period. The net sediment accumulation rate from the contributing

basin was 0.311 acre-foot per square mile per year for the same period.

Reservoir Sedimentation Survey

A summary of the reservoir sediment data for the 1980 survey is contained in

table 2. The data include a tabulation of incremental sediment inflow volume

and sediment accumulation computed for the periods between the original

(1915) and the 1957, 1969, and 1980 surveys. Both types of data are valuable

in practical and research studies.

RESERVOIR AREA AND CAPACITY

The 1980 reservoir surface areas were computed by the Width Adjustment Method

described by Pemberton [2]. Briefly, the method used entails computing the

1980 contour areas between any two ranges by applying an adjustment factor

to the 1915 contour area between the two ranges. The adjustment factor was

determined as a ratio of the new average width to the original average width

for both the upstream and downstream ranges at a specified contour. Computations were facilitated by subdividing the reservoir into segments using the

sedimentation range lines to delineate the limit of each segmental boundary.

For any given contour elevation, the 1915 surface areas were multiplied by

the adjustment factor to compute the 1980 surface area of each segment. The

total surface area at a given contour elevation was computed as the summation

of all segmental areas at that elevation.

The 1980 surface areas were used as control parameters for computing the

reservoir capacities by electronic computer. The program procedure included

computation of 0.01- to 1-foot area increments by linear interpolation

between 10-feet contour intervals. The progressive computational procedure

began by testing the initial capacity equation over successive intervals to

determine whether it was within an allowable error limit (0.0001 in this

case). This capacity equation was then used over the whole range that fit

within the allowable error limit. For the next interval, beginning where

the initial allowable error limit was exceeded, a new capacity equation

(integrated from the basic area equation over that interval) began testing

the fit until the limit was exceeded. Thus, the capacity curve was defined

by a series of curves or splines, each falling within a specific elevation

interval as constrained by the limiting error. The final area equations were

subsequently derived by differentiation of the capacity equations. Capacity

equations are of second order polynomial form:

6
y = a1 + a2 x + a3

where: y = capacity

x = elevation above an elevation base

ai = intercept

a and a = coefficients

Results of the 1980 area and capacity computations are listed in columns (4)

and (5) of table 1. Listed in columns (2) and (3) of this table are the

original area and capacity values. A special set of area-capacity tables

has been published separately for the 0.01-, 0.10-, and 1-foot elevation

increments [3]. Both the original and 1980 area-capacity curves are plotted

on figure 90. At spillway crest elevation 4,407, the 1980 capacity is

2,110,298 acre-feet and the surface area is 36,897 acres.

During the course of the area and capacity computations, it was discovered

that the capacity had increased in some segments of the reservoir since

the last complete survey in 1969. These gains in capacity were attributed

in part to the effects of compaction of sediments in those segments. An

additional factor influencing the increased capacities was the precision used

to measure the profiles during the 1980 survey. The 1915 profiles were

measured from the original topographic map (contour interval, 10 feet). As a

result, the apparent profile width changes indicated between the 1915 and

1980 surveys were, in many instances, due to inaccuracies in the original

profile data.

Mission of the Bureau of Reclamation

The Bureau of Reclamation of the U.S. Department of the Interior is

responsible for the development and conservation of the Nation's

water resources in the Western United State&

The Bureau's original puipose "to provide for the reclamation of arid

and semiarid lands in the West" today covers a wide range of interrelated functions. These include pro v/ding municipal and industrial water

supplies; hydroelectrIc power generation; irrigation water for agriculture; water quality improvement; flood control; river navigation; river

regulation and control; fish and wildlife enhancement; outdoor recreation; and research on water-related design, construction, materials,

atmospheric management, and wind and solar power.

Bureau programs most frequently are the result of close cooperation

with the 11.5. Congress, other Federal agencies, States, local governments, academic institutions, water-user organizations, and other

concerned groups.

A free pamphlet is available from the Bureau entitled "Publications

for Sale." It describes some of the technical publications currently

available, their cost, and how to order them. The pamphlet can be

obtained upon request from the Bureau of Reclamation, Attn 0-922,

P 0 Box 25007, Denver Federal Center, Denver CO 80225-0007.
