The Natural Resources Conservation Service surveyed Edward Arthur Patterson Lake in 1991. The field data

were used for computing the storage-elevation relationship. The report describes the survey procedures used

during the 1991 collection and provides data for future surveys.

As of 1991, at reservoir spillway crest elevation 2,420.0 (feet), the surface area was 1,194 acres with a total

storage capacity of 8,612 acre-feet. Since the reservoir's initial filling in May 1950, 1,885 acre-feet of sediment

have been trapped in Edward Arthur Patterson Lake. The average annual sediment accumulation rate is 46

acre-feet per year for the 41-year period of operation.

INTRODUCTION

Dickinson Dam and Reservoir (Edward Arthur Patterson Lake), part of the Dickinson Unit of

the Pick-Sloan Missouri Basin, are located on the Heart River in Stark County, 1.5 miles west

of Dickinson, North Dakota (fig. 1). The reservoir provides municipal water for Dickinson and

downstream irrigators. The reservoir also provides flood control, recreational, and fish and

wildlife benefits.

Dickinson Dam was constructed from March 1949 to March 1950. The earthfihl dam contains

324,000 cubic yards of material with a structural height of 62 feet and a crest length of 2,275

feet. The spiliway crest elevation was 2,416.5, top of active conservation. Modifications to the

dam, completed in 1982, raised the spillway crest 3.5 feet to elevation 2,420.0.

At the time of closure, May 1950, reservoir surface area at the spiflway crest, elevation 2,416.5

feet, was about 862 acres with an active capacity of 6,952 acre-feet. Reservoir surface area at

elevation 2,420.0 was about 1,194 acres with an active capacity of 10,497 acre-feet. These

estimates were developed using Reclamation's ACAP92 (1992) program to determine the

change in reservoir storage. These numbers differ from the original area-capacity tables.

The drainage area at Dickinson Dam is about 406 square miles. The basin averages 11 miles

in width over the 36 miles upstream from Edward Arthur Patterson Lake.

SUMMARY AND CONCLUSIONS

This report presents the results of an investigation to monitor changes in Edward Arthur

Patterson Lake after 41 years of reservoir sediment accumulation.

The NRCS (Natural Resources Conservation Service) State Office, formerly known as the Soil

Conservation Service, surveyed the lake in 1991. Standard land surveying techniques were

used to survey the lake.

The total storage capacity of the reservoir from the 1991 survey is estimated to be 8,612 acrefeet with a surface area of 1,194 at elevation 2,420.0.

DESCRIPTION OF THE BASIN

Dickinson Dam drainage basin is located in southwestern North Dakota. The area of the basin

is 406 square miles. During the 1900s, much of this area was overgrazed. During the drought

in the 1930s, stream erosion and channelization increased, but channels have become grass

covered and the runoff potential has decreased. The basin is mostly gently rolling farm land

with some interspersed pasture land.

Average annual precipitation is about 16 inches, and mean annual runoff is about 19,400 acrefeet. Temperatures range from -37 to 108 °F with a mean temperature of 42 °F.

* The definition of terms such as structural height,' hydraulic height, etc. may be found in manuals such as

Reclamation's Design of Small Dams and Guide for Preparation of Standing Operating Procedures for Dams and

Reservoirs, or ASCE's Nomenclature for Hydraulics.
SURVEYS

Survey History

The original sediment ranges were located and surveyed by Reclamation; the survey was

started September 1949 and completed in July 1950. In 1991, the reservoir sediment range

lines were re-surveyed again by the NRCS.

Survey Methods and Equipment

The 1991 survey was conducted by personnel from the NRCS in Bismarck and their field office

in Dickinson. According to the Dakotas Area Office, the NRCS used standard land surveying

procedures to profile each range line. Depth readings were taken from a boat using a rod to

probe the bottom. The original survey designated the right bank, looking downstream, as the

0+00 station, as did the NRCS survey. Figure 2 displays the surveyed range lines on the

original contour map. Also, the original area-capacity curve and table are on the map. Table

3 has the coordinates of the end points for the range lines.

RESERVOIR AREA AND CAPACITY

Development of 1991 Contour Areas

The reservoir was subdivided into segments for sedimentation analysis and to better represent

storage changes. The surveyed range lines were used to delineate the limit of each segmental

boundary. The method used to compute the new reservoir volume caused by sediment inflow

takes the segmented areas (area between the range lines) and determines where the sediment

has filled in the original areas. This determination was done by comparing the plots of the

original and 1991 range line cross-sections simultaneously. The comparison indicated the

lateral distribution of the sediment at the different measured cOntour elevations. Where these

plots indicate changes have occurred on the side slopes of the reservoir, a decision was made

to determine whether the change was caused by actual deposition, erosion, or survey

inaccuracies. No area adjustment was made if the measured change was judged to be caused

by survey inaccuracy. The 1991 surface areas were developed by calculating the 1991 average

bottom sediment elevation and comparing it to the original thalweg elevation at each range

line. In each segment, the original surface area of each contour elevation that was below the

1991 average bottom sediment elevation was digitized and subtracted from the original area,

resulting in the 1991 surface areas. The 1991 total reservoir surface area at a given contour

is the original total area minus the summation of all segmental areas silted in at that

elevation. The 1991 total area computation results are listed in column (2) of table 2.

The maximum elevation of the reservoir was 2,421.13 feet on June 9, 1982; therefore, no

surface area change was assumed to occur above elevation 2,420.0. This assumption is

illustrated by the cross-section plots of the range lines which show that the sediment did not

accumulate above the spillway crest elevation of 2,420.0. Everything below elevation 2,398.0

has filled in with sediment. The original area-capacity table was done using 4-foot contour

intervals from elevation 2,390.0 to 2,430.0 feet; therefore, the new table is consistent with the

original.
1991 Revised Storage Capacity

The 1991 surface area and elevation relationships were used as control parameters to compute

reservoir capacities by means of Reclamation's area-capacity computer program ACAP92

(Reclamation, 1992). The program computes surface areas for 0.01- to 1.0-foot area increments

by linear interpolation between the given contour areas. The 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 margin.

This one equation is used over the whole range that fits within this error term. At the next

interval beyond, a new capacity equation (integrated from the basic area equation over that

interval) begins testing the fit until it too exceeds the error term. The capacity curve thus

becomes a series of curves, each fitting a certain region of data. The final area equations are

obtained by differentiation of the capacity equations. Capacity equations are of the form:

y = a + a2x + a3x2

where:

y = capacity

x = elevation above a reference base

a = intercept

a2 and a3 = coefficients

The results of the 1991 area and capacity computations are listed in columns (4) and (5) of

table 2. Listed in columns (2) and (3) of this table are the original area and capacity values.

.To allow comparison of the original capacities with the 1991 capacities, the original capacity

values have been revised by using the same curve fitting technique as was used for the 1991

area and capacity computation (ACAP92). Both the original and 1991 area and capacity curves

are plotted on figure 3. Area and capacity tables have been published separately for the 0.01-,

0.10-, and 1-foot elevation increments (Reclamation, 1995). The 1991 survey determined that

the reservoir has a total storage capacity of 8,612 acre-feet and a surface area of 1,194 acres

at spiliway crest elevation 2,420.0. The table on the following page contains the dead, inactive,

and conservation capacities.

SEDIMENT ANALYSES

Sedimentation Accumulation

Total sediment volume that has accumulated in Edward Arthur Patterson Lake since May

1950 is 1,885 acre-feet at the spiliway elevation of 2,420.0. The average annual sediment

accumulation rate is 46 acre-feet per year for the 41-year period of operation. Over the

contributing basin area, this rate equates to 0.11 acre-feet per square mile per year.

Sedimentation Summary

The results of the sediment data and volume computations for the 1991 survey are shown in

tables 1 and 2. The data include a tabulation of incremental sediment inflow volume and

sediment accumulation computed for the period between initial conditions and the 1991

resurvey. Table 1 includes information on the drainage basin, records of estimated inflow,

reservoir operations, and reservoir storage.

RESERVOIR SEDIMENT DISTRIBUTION

Longitudinal Distribution

The distribution of sediment throughout the length of the reservoir is illustrated in part by

plots of the thaiweg profiles representing the original and 1991 resurveyed profiles of the main

channel (fig. 4). Field notes describing the location of the thalweg were not available for either

survey. Therefore, the lowest elevation at each range line was used as the thaiweg.

Lateral Distribution

The 41 range lines originally surveyed in 1950 were resurveyed in 1991. The original and the

1991 range cross-section data are plotted together to depict the changes that have occurred and

to represent the general lateral distribution of sediment within the reservoir (figs. 5 to 45).

Most of the sediment deposition is located within the historic river channel.

Depth Distribution

The computation of sediment distribution by elevation is given in section 43 of table 1. The

entire volume of sediment is below the spillway crest, elevation 2,420.0. About 48 percent of

the deposited sediment is found below the top of inactive pooi, elevation 2,405.0 feet. The

remaining 52 percent of the sediment is found between elevations 2,406.0 and 2,418.0 feet.
