Because there are prior appropriators of ground water and because it is impractical to capture the entire natural discharge, the safe yield estimate for new wells in the lower Camp Creek area is estimated to be 2000 acre feet per year. Dependability of quality The area of apparent ground-water quality degradation is located only two to four miles upstream from the best geologic and hydrologic location for new wells. The seriousness of this depends principally on the source and extent of the contamination. If it is the result of a short-term introduction of contaminants by man in a concentrated area, the effect will disperse and not cause as serious a lowering of quality at a downstream well field as would be the case if a continuous wide-spread source exists. Further investigations are needed in order to determine the source or sources and the threat to downstream wells. At an assumed travel rate of 1/3 mile per year, effects of the present contamination may reach the proposed well field within ten years. Until additional information is available, development of this supply should be done only with the full knowledge that the quality may deteriorate in such a period of time. Hay Gulch Alluvium Hay Gulch is an intermittent, poorly developed surface stream tribu- tary to the South Platte River. It heads in T1N, R62W and trends in a northerly direction joining the South Platte Valley in T4N, R61W, near Dearfie1d. The entire watershed lies in eastern Weld County. Investigations of the Hay Gulch alluvium included study of drillers' logs of test holes and wells previously drilled in the area. In addition, four test holes were drilled in 1973 specifically for this study. - 13 - M. W. BITTINGER AND ASSOCIATES, INC.
