16. ABSTRACT

Altus Reservoir was surveyed in 1967 to gather the data needed in computing the latest reservoir capacity. The

data were also used to compute the quantity of sediments accumulating in the reservoir since the dam was

closed in 1940. Capacity of the reservoir is 134,000 acre-ft and the surface area 6,260 acres at spillway crest

elevation 1559 ft. Sediments accumulated in the reservoir at an annual rate of 838 acre-ft between 1940 and

1947. Thirty sediment samples of reservoir deposits were collected from 23 reservoir range sites. An average

unit weight of 70 lb/cu ft was determined from analyses of samples collected during the 1948, 1953, and 1967

surveys. Particle size analyses of these samples indicated an average breakdown of 29% clay, 32% silt, and 39%

sand. Sonic depth recording mechanism was used to run the hydrographic survey. Reservoir capacity was

computed based on areas determined by a width ratio method. Sediments have deposited longitudinally to

depths of 1 to 9 ft throughout the reservoir length. Depths ranged from 1 to 6 ft for the laterally deposited

sediments.

GENERAL INFORMATION

Location and Ownership

Altus Dam is located on the North Fork of the Red

River about 18 miles north of Altus, Oklahoma. The

reservoir is situated in Greer and Kiowa Counties. The

dam and reservoir are owned by the U.S. Government

and operated by the Bureau of Reclamation,

Department of the Interior.

Description of the Dam

Altus Dam is a concrete gravity type, partially curved

structure faced with granite masonry on both faces

except the downstream face of the overflow section. It

rises 110 feet above its foundation and is 1,112 feet

long. Incorporated within the dam section are both

controlled and uncontrolled overflow-type spillways

and an outlet works that delivers water into the project

canal system. The spillway capacity is 58,000 cubic

feet per second regulated by nine radial gates. A

drawing of the general plan and sections is shown in

Figure 1.

Description of the Reservoir

The present capacity of the reservoir is 134,549

acre-feet at the spillway crest elevation 1559 feet. This

shows a loss of 22,119 acre-feet since the dam was

closed in 1940. The present reservoir surface area is

6,260 acres at elevation 1559 feet. The reservoir is 13.1

miles long from the dam to the head of the reservoir, It

has an average width of 1 mile. Figures 2 and 3 are plan

maps of the reservoir.

The reservoir was designed to provide water for

irrigation, flood control, an augmented municipal

water supply for the city of Altus, fish and wildlife

benefits, and recreational facilities.

Drainage Area Description

The drainage area above Altus Dam is 2,515 square

miles of which 399 square miles is probably

noncontributing. It originates in the Panhandle of

Texas about 15 miles west of Amarillo, Texas, and

extends eastwardly into western Oklahoma. The area is

drained by the North Fork of the Red River, whose

principal tributaries are McClellan and Sweetwater

Creeks.

There are no major structures in the watershed that

would reduce the sediment contribution to Altus

Reservoir. However, the restriction of the lake imposed

by the approaches to Granite Bridge and another

restriction existing naturally about 3000 feet above the

dam do affect the distribution of sediment after it

enters the lake.

Further description of the drainage area regarding

geology, topography, soils, land use, and other features

is given in a Bureau of Reclamation report published in

1949.'

Hydrographic Records

Streamflow records of the North Fork of Red River

near Carter, Oklahoma, were used to estimate the

inflow to Altus Reservoir. These records, adjusted for

drainage area, showed an annual average inflow of

104,400 acre-feet for 20 years of record (1944-62,

1964-66). Outflow from the reservoir was based upon

records of the river at the gaging station below the

dam. These showed an outflow of 36,340 acre-feet per

year for a 14-year period (1950-62, 1964-66). The

outflow is controlled by releases from the dam. Altus

Reservoir operation ranged from a minimum elevation

of 1523.20 feet in 1945 to a maximum of 1562.10 feet

in 1951.

SURVEYS, SAMPLING, AND

EQUIPMENT

Two surveys of Altus Reservoir were previously run in

1948 and 1953 using a combination contour and range

method. The range method was used for the 1967

survey that began in February 1967 and completed

April 14, 1967. Results of each survey are summarized

inTable2(pages l2and 13).

Surveying Methods

Field survey work was begun by locating and flagging

all 25 reservoir sedimentation range ends (Figures 2

and 3) that had been permanently monumented during

previous surveys. In some cases it was necessary to

relocate the range and monuments that had been

removed or possibly destroyed for one reason or

another. The ranges were profiled across their full

length. Standard land surveying procedures and

equipment were used to run levels along each range line

from the permanent range end monuments down to

the water surface from each side of the reservoir.

Stations were temporarily established at the terminal

land points near water's edge for use in the

hydrographic survey.

Figure 2. Reservoir sedimentation range system.
Figure 3. Reservoir sedimentation range system.
The hydrographic survey was run in April 1967 using

sonic depth recording equipment (Figure 4) to sound

the submerged portion of the ranges. The equipment is

installed in a sounding boat as shown in Figure 5. The

boat is first positioned on range line as near to the

shore as possible. Then the line is profiled from the

water's edge station using a level rod and stadia or tape

to measure the distance to the center point of the

transducer. The depth recorder is started up and the

boat is propelled across the range at speeds of about 3

to 5 feet per second (Figure 6). A man on shore keeps

the boat on line through radio communication with the

boat operator (Figure 7). The distance measuring

machine shown in Figure 8 is used to measure

horizontal distances across the reservoir. The machine

provides a way of noting "fix" lines on the sonar chart

that is contained in the recorder cabinet shown in

Figure 9. Vertical control was maintained by

referencing the recorded soundings to the reservoir

water surface indicated by gage at the dam which was

read each day of the survey operation.

Sampling Methods and Equipment

Ten samples of the underwater reservoir sediment

deposits were collected with a gravity core sampler that

is suspended from a frame mounted on a raft (Figure

10). The sampler is operated with a power winch using

a 0.25-inch cable. It is allowed to fall free into the

sediment deposits to the greatest possible penetration.

After the sampler is raised it is brought onto the raft,

the cutting shoe at the bottom is removed, and the

plastic tube containing the sediment sample is

withdrawn. A hacksaw is used to cut that part of the

tube holding the sample and each end of the tube is

capped and identified for analysis.

Samples were collected from 13 of the upstream ranges

using a 2-inch diameter plastic tube that was pounded

into the sediment deposits with a rubber mallet (Figure

11).

The field density apparatus was used to take samples at

seven of the upstream ranges in the manner prescribed

by a Bureau of Reclamation manual.2 Figure 12 shows

one of these samples being taken.

RESERVOIR SEDIMENT DISTRIBUTION

Longitudinal Distribution

A summary of the sediment distribution computations

for Altus Reservoir is contained in Table 1. In Column

6 of the table are the actual accumulated sediment

volumes determined from the 1967 survey. Total

sediments accumulated in the reservoir since the

original survey of 1940 amounted to 22,119 acre-feet

at spillway crest elevation 1559 feet. Column 7 lists the

volume of sediment accumulated at corresponding

reservoir elevations expressed as percentage of the

actual total sediment volume, 22,119 acre-feet. To

check the theoretical distribution, the Empirical

Area-Reduction Method was used to compute the

sediment distribution of 22,119 acre-feet in the

reservoir. The reservoir depth-capacity relation plotted

for the 1940 (original) data in Figure 13 showed the

reservoir to be a Type II. A plot of the curves to

determine the depth of sediment at the dam is shown

in Figure 14. Results of the sediment distribution

computations are listed in Columns 8, 9, and 10 of

Table 1. The theoretical computations showed the

sediment would reach an elevation of 1512.6 feet

compared to the actual elevation of 1509 feet. The

sediment disposition curves plotted in Figure 15 show

a comparison of the actual with the theoretical

distribution. The curves graphically show the

percentages of reservoir depth plotted against the

sediment deposited. Inspecting the curves shows that

the actual and Type II distribution compare favorably

throughout the depth range. Deviations of the

sediment deposited do not exceed 13 percent for

reservoir depths ranging from 60 to 80 percent. In an

actual project planning study, results of the Type II

computations would have been used which show about

a 3-1/2-foot difference in the elevation of sediment at

the dam when compared to the observed data. A

sediment accumulation curve covering the 1940-67

period is plotted in Figure 16 using the values in

Columns 1 and 6 of Table 1.

A further idea of how the sediment was distributed

longitudinally through the reservoir can be obtained by

studying the profiles in Figure 17. The points plotted

to define these profiles are not, in every case, the valley

thalweg; i.e., the minimum point of the range line cross

section. The thalweg elevation of the old floodplait

Lateral Distribution

Profiles of all 25 sedimentation ranges surveyed in

1948 and 1967 were plotted in Figures 28 through 52

in the appendix. These profiles show generally how

sediments were laterally distributed in the reservoir.

Sediments are shown depositing laterally to depths of 1

to 4 feet from sedimentation Ranges 1 to 11, 8 miles

above the dam. From sedimentation Range 13 on

upstream to Range 19, the laterally deposited

sediments averaged about 6 feet except at Range 15

that showed an average depth of about 11 feet. The

cross sectional plottings show that Ranges 20 and 21

were essentially filled laterally with sediment to

maximum water surface, 1564 feet.

SEDIMENT ANALYSES

*Excludes maximum of 13 feet at Range 14A.

**Excludes maximum of 18 feet at Range 14A.

The extreme rise in the depths of sediment at Range

14A results from the influence of Granite Bridge

downstream. However, the narrows area occurring

naturally at Range 2A had little influence on the

sediment depositional pattern immediately upstream

(Range 3).

Sediment Accumulations

The total volume of sediments that has accumulated in

Altus Reservoir amounted to 22,120 acre-feet at

spillway crest elevation 1559 feet (Item 38a, Table 2)

as computed by subtracting the 1967 from the 1940

capacity. An average annual sediment accumulation

rate of 838 acre-feet was determined for the 26.4 years

since the dam was built. Sediments deposited at a rate

10
of 0.398 acre-foot per square mile per year for this

period.

Reservoir Sedimentation Summary

Table 2 gives a comprehensive summary of the

reservoir sediment data relative to each survey that has

been run. The data include tabulating incremental

sediment inflow volumes as well as sediment yield rates

computed for periods between surveys. Both of these

values are considered important for practical and

research use.

Unit Weight Analyses

During the 1948, 1953, and 1967 surveys, 69 physical

samples of the reservoir sediment deposits were

collected. A summary of the results of each sample

taken during these surveys is contained in Table 3. Unit

weights, median diameters, and percentages of clay,

silt, and sand are tabulated.

Analyses were made of the sample data collected to

determine a unit weight for the inflowing deposited

sediments. A weighting process was used to do this by

computing the unit weight averages of the sediments

sampled within individual segmented reservoir areas.

These averages were multiplied by the incremental

sediment volumes and the resulting products summed.

The sum was divided by the total sediment volume

giving a weighted unit weight of 70.2 pounds per cubic

foot. This compares with unit weights of 66.9 and 52.3

pounds per cubic foot determined for the 1953 and

1948 surveys, respectively.

An empirical method3 was used to compute the unit

weight applying the representative clay, silt, and sand

size gradations subsequently described. Assuming a

Type II reservoir operation,4 an initial unit weight of

70.5 pounds per cubic foot was computed which

compares favorably with the 70.2 weighted value

described above. However, by considering a

compaction correction using the method of Miller,5 a

unit weight of 73.4 pounds per cubic foot was

determined for a 26-year period.

Particle Size Analyses

A study was made of the particle size analysis tests run

on 62 of the samples collected in the 1948, 1953, and

1967 surveys. The graphs in Figures 18 through 24

contain the particle size analysis curves for each

sample. Representative particle sizes in the clay, silt,

and sand ranges were determined by the weighting

process as was used in the unit weight analyses. The

data in Figures 18 through 24 were used to determine

the percentages of clay, silt, and sand of each range

sample taken within the same segmented areas used in

the unit weight analyses. The representative size was

computed to be 29 percent clay, 32 percent silt, and

39 percent sand.

Estimated Sediment Inflow to Reservoir

An attempt was made to estimate the sediment inflow

to the reservoir for comparison with the inflow

determined from the 1967 survey. The estimate is

based on a sediment rating curve that was developed

from records available for the period March 1, 1948 to

September 30, 1953, shown in Figure 25. Records of

the North Fork Red River near Carter, Oklahoma, were

used. The sediment rating curve was used in

conjunction with the flow duration curve (Figure 26)

for the period covering water years 1941-1965. The

results of this analysis in Table 4 show an average total

sediment discharge of 1,475,000 tons per year

assuming 15 percent for the bedload discharge. This

value was adjusted further to take into account the

drainage area (149 square miles) between the Carter

gaging station and Altus Dam. Assuming an annual

sediment yield rate of 0.4 acre-foot per square mile for

this area and assuming a unit weight of 70.2 pounds

per cubic foot as determined by the 1967 survey, a

sediment discharge of 91,100 tons per year was

computed. Adding this to the total in Table 4

(1,475,000) gives an estimated 1,566,100 tons per year

total sediment inflow to the reservoir. This compares

to the total sediment inflow of 1,430,720 tons per year

measured by the 1967 survey. A difference of about

9.5 percent is indicated between estimated and

measured sediment inflow rates. This indicates a

reasonable check from a practical standpoint. However,

it should be pointed out that several factors have been

determined by judgment in the course of the

computations. Included in these are the major factors

of the assumption for bedload (15 percent) the

assumed annual sediment yield rate of 0.4 acre-foot per

square mile as well as the assumed unit weight of 70

pounds per cubic foot.

RESERVOIR AND AREA

AND CAPACITY

The 1967 Altus Reservoir surface areas were

determined by a method using reservoir sedimentation

range width ratios. Briefly, this method entails

comparing the 1967 range widths with the 1948 widths

at corresponding elevation intervals. The results are

tabulated in the ratio form 1967/1948. To facilitate

the computations the reservoir is divided into segments

using the sedimentation range lines to delineate the

segmental boundaries. The 1948 reservoir topographic

maps were used to planimeter the surface areas at

5-foot contour intervals. For corresponding elevations,

these areas were multiplied by the width ratios

obtained and the 1967 surface areas were determined.

The 1967 surface areas were the control parameters for

computing the reservoir capacities with the electronic

computer. The computer program computes 1-foot

area increments by linear interpolation between the

5-foot contour intervals. Respective capacities and

capacity equations are then obtained by integration of

the area equations. The initial capacity equation is

tested over successive intervals to check whether it fits

within an allowable error limit (0.01). This one

equation is then used over the whole range that fits

within the allowable error limit. For the next interval

beginning at the elevation where the initial allowable

error limit has been exceeded, a new capacity equation

(integrated from the basic area equation over that

interval) begins testing the fit until it too exceeds the

error limit. Thus, the capacity curve is defined by a

series of curves, each falling within a specific elevation

interval as constrained by the limiting error. The final

area equations are subsequently derived by

differentiation of the capacity equations. Capacity

equations are of second order polynominal form, y =

a1 + a2x + a3x2, where y is the capacity, x is the

elevation above an elevation base, a1 is the intercept,

and a2 and a3 are coefficients. Results of the 1967

reservoir area and capacity computations are listed in

Columns 4 and 5 of Table 1 (page 8). Listed also in

this table in Columns 2 and 3 are the original area and

capacity values for comparison purposes. Both the

original and 1967 area and capacity curves are plotted

in Figure 27. At elevation 1559 feet (uncontrollable

spillway crest), the present capacity of Altus Reservoir

is 134,550 acre-feet and the surface area is 6,260 acres.

SUMMARY AND CONCLUSIONS

The 1967 sediment survey report of Altus Reservoir

briefly describes the field surveying and sediment

sampling procedures and equipment. Also discussed are

the analytical methods used to measure and study the

nearly 26.5 years of reservoir sediment accumulation.

The survey was primarily run to gather the necessary

data for use in computing the latest capacity of Altus

Reservoir.

Standard land surveying methods were used to run

levels from the permanent range end monuments to

stations that were temporarily established at the

reservoir water's edge. The hydrographic survey was

run using sonic depth recording equipment operated

from a boat. This system continuously recorded

reservoir depths on charts as the boat was propelled

across the range line. Five men were required to run

the hydrographic survey. A distance measuring

machine was used to maintain horizontal control and

the water surface elevations determined from the gage

at the dam were used as a reference for vertical control.

Ten sediment samples of the reservoir deposits were

collected with a gravity core sampler and 13 more

using a 2-inch diameter plastic tube driven by hand

into the deposits with a rubber mallet. Field density

apparatus was used to take seven additional samples at

upstream range locations. Analyzing these samples and

others collected during the 1948 and 1953 surveys

resulted in determining a unit weight of 70.2 pounds

per cubic foot and a representative size of 29 percent

clay, 32 percent silt, and 39 percent sand.

The longitudinal and lateral deposition of sediments in

the reservoir generally followed the usual pattern.

Longitudinally, the sediments deposited between the

1940 and 1967 surveys to average depths of 6.5 feet

for a distance from the dam to a mile above the dam,

2.5 feet from 1 to 3-1/2 miles above the dam, 7.5 feet

from 3-1/2 to 7 miles above dam, and 14 feet from 7

to 12 miles above the dam. Between the 1948 and

1967 surveys, these deposited depths varied from less

than 1 to 2 feet for a distance from the dam to 8 miles

above the dam and averaged about 8.5 feet from 8 to

12 miles above the dam. Laterally, the reservoir range

cross sectional profiles for the 1948 and 1967 surveys

show sediments deposited to depths of 1 to 4 feet for

the area 8 miles above the dam. For the area from 8 to

12 miles above the dam the laterally deposited

sediments averaged about 6 feet with the greatest

average depth of about 11 feet at 10 miles above the

dam. For all practical purposes sediments have

essentially deposited to maximum water surface, 1564

feet, in the reservoir area beginning at 12 miles above

the dam.

The capacity of Altus Reservoir as determined by the

1967 survey is 134,550 acre-feet and the surface area

6,260 acres at spillway crest elevation 1559 feet (see

area-capacity curves in Figure 27). The 1967 reservoir

surface areas were determined by a width ratio method

described on page 26. The electronic computer was

used to compute areas at 1-foot increments by linear

interpolation. The computer was also used to compute

the reservoir capacity which is defined by a series of

curves obtained by integrating the area equations over

an elevation interval within a restricted error limit. The

capacity data were also compiled at 1-foot intervals.

A comprehensive summary of the reservoir sediment

data for the 1967 survey is contained in Table 2.

Sediments have accumulated to a volume of 22,120

acre-feet at elevation 1559 feet since the dam was

closed in 1940. This indicates a loss in reservoir

capacity of about 14 percent. The average annual

sediment accumulation rate of 838 acre-feet was found

for the 1940-67 period. Sediments deposited at a rate

of 0.398 acre-feet per square mile annually during this

period.

CONVERSION FACTORS-BRITISH TO METRIC UNITS OF MEASUREMENT

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

Society for Testing and Materials )ASTM Metric Practice Guide, E 380-68) except that additional factors (0)

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-amperel 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 980665 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 rn/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 genera) 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.

ABSTRACT

Altus Reservoir was surveyed in 1967 to gather the data needed in computing the latest

reservoir capacity. The data were also used to compute the quantity of sediments accumulating

in the reservoir since the dam was closed in 1940. Capacity of the reservoir is 134,000 acre-ft

and the surface area 6,260 acres at spillway crest elevation 1559 ft. Sediments accumulated in

the reservoir at an annual rate of 838 acre-ft between 1940 and 1947. Thirty sediment samples

of reservoir deposits were collected from 23 reservoir range sites. An average unit weight of 70

lb/cu ft was determined from analyses of samples collected during the 1948, 1953, and 1967

surveys, Particle size analyses of these samples indicated an average breakdown of 29% clay,

32% silt, and 39% sand. Sonic depth recording mechanism was used to run the hydrographic

survey. Reservoir capacity was computed based on areas determined by a width ratio method.

Sediments have deposited longitudinally to depths of 1 to 9 ft throughout the reservoir length.

Depths ranged from 1 to 6 ft for the laterally deposited sedimerlts.
