• part of ,the. alluvium. Well SG=A, is installed with a pump. It <br />was estimated that the alluvium in-this. area could yield about <br />27.8 gpm of water (Wright Water Engineers, 1977). The actual <br />pumping rate is much lower; the average pumping rate during <br />May, June and July, 1982 was 4.5 gpm. <br />The water table in the alluvium shows high seasonal <br />fluctuations. During April and May the water level can be as <br />high as 4 feet below ground surface; however, during late sum- <br />mer, fall and winter the water level drops to as deep as <br />40 feet below ground surface. On Plate 4 the results of over <br />three years of water levels monitoring in two wells is shown. <br />Monitoring well SG-C is located about 75 feet south of the <br />pumping well (SG-A) and monitoring well SG-B about 116 feet <br />west of the pumping well. The results of monitoring in well <br />SG-B are considered as representative for this part of the <br />Stevens Gulch alluvium; it is believed that because of the low <br />. pumping rate, its distance from the pumping well and its lo- <br />cation close to the stream, the effect of pumping on water <br />level in this well is minimal. <br />Water quality in the Stevens Gulch alluvium is general- <br />ly good. The total dissolved solids content varies between 200 <br />and 500 mg/1. <br />3.4 LAND USE AND FARMING <br />3.4.1 NORTH FORK OF THE GUNNISON RIVER <br />Much of the land within and adjoining the river valley <br />supports fruit orchards.
