and Farmers Ditch, both on the right (north) side of the val- <br />ley. <br />Sediments deposited within the North Fork valley are <br />water bearing and most ground water occurs in sands and gravels. <br />At this time no monitoring wells are available to assess depth <br />to ground water and ground water quality within the study area. <br />However, from the State Engineer's record of registered wells <br />it is possible to make the following conclusions: wells are <br />typically 30 to 100 feet deep and the water table is usually <br />between 10 and 25 feet below the ground surface. Water quality <br />is relatively good close to the river and deteriorates with in- <br />creasing distance from the river. <br />a <br />3.3.2 STEVP;NS GULCH <br />• Stevens Gulch is an ephemeral stream which drains an <br /> area of approximately 6 sq. miles. Major flows occur during <br /> spring snowmelt and after heavy rains. A stream gaging station <br /> consisting of a Parshall flume with a continuous recorder is <br /> being installed near the Orchard Valley mine entry. At this <br /> point the drainage area is about 4.01 sq. miles. <br /> The major part of the Stevens Gulch valley has either <br /> very shallow alluvium or else alluvial sediments ,sre not present. <br /> Only in a few locations where the gradient is more gentle than <br /> average was a greater thickness of alluvial sediments deposited. <br /> One of these areas is in Section 13 (T 13 S, R 92 W) where the <br /> CWI well field is located. In this area, four wells were in- <br /> stalled in 1977 to provide a water supply and information about <br /> the water bearing strata. The wells are between 65 and 97 <br /> feet deep and screened in the lower, more permeable <br />• - 8 <br /> c~waocor+w~nn~.iNC. <br />
