During the course of the investigation, information on existing wells

was obtained. In addition, eight test holes were drilled in T4N, R54W,

specifically for this study. Figure 2 shows the location of these test

holes along with other wells in the area.

The saturated thickness of the alluvial material provides a good

indication of the best location for well development. Figure 2 shows con-

tours of equal saturated thickness for the lower portion of the Camp Creek

al1,uvium. This map indicates that the saturated thickness exceeds 120 feet

in the central portion of the channel. The configuration of the channel

and the saturated thickness can also be seen in Figure 3 which is a cross-

section drawn through the eight test holes drilled in 1973. From the

information available, the best location for new well development exists

in Sections 24 and 25, T4N, R55W.

Figure 2 can also be utilized to estimate the quantity of water in

storage. Using only the area within the 10-foot contour of saturated

thickness and an assumed storage coefficient of 0.15, the amount of ground

water in storage in the area shown on Figure 2 is conservatively estimated

at 161,000 acre feet. It is conservatively estimated that the remaining

portion of the Camp Creek alluvium should contain an additional 24,000

acre feet. Thus, the best estimate for water in storage in the Camp Creek

alluvium at this time is 185,000 acre fpet.

Present ground-water uses

I

As near as can be determined, there are three irrigation wells and

five industrial wells tapping the Camp Creek alluvium. In addition, there

are many livestock wells in that the predominant land use overlying th~

aquifer is for livestock grazing. The three irrigation wells are used to

supply center-pivot sprinklers irrigating approximately 135 acres each.

Assuming an average annual consumptive use of irrigation water of 1-1/2

acre feet per acre, the estimated net consumptive use of ground water for

irrigation is 600 acre feet per year.

The five industrial wells are utilized for secondary recovery of oil.
