• the ground waters are captured by the outcrop of Mcnefce beds <br />along the northern boundary of Section 16, 35N, lOW; that this <br />capture area is 2.5 miles long by 400 feet wide; that the aititual <br />precipitation is 18 inches per year; that 90~/~ of the total yearly <br />precipitation falling on this area flows down the steep north slope <br />(see A4ap A) anii only 10~/~, into the Menefee beds; then, a total of <br />17 acre feet of water per year would enter the Menefee from this <br />capture area. <br />Assume further that 20~/~ of the beds in the 200 feet of Mene- <br />fee section capture all of the 17 acre feet of water and have an <br />average porosity of 20/0. CJnder these assumptions, the down-dip <br />dimension of the interval of saturated beds will total about 12 feet <br />• per year. These yearly driblets will elongate as they move down <br />dip to the south replenishing and saturating only partially the aqui- <br />fers along tl~e way, <br />Omitted in this discussion is the possible contribution from <br />the large, almost dip-slope, area south of the Menefee outcrop <br />belt along Lightner Creek. Drillltoles were without exception very <br />dry in passing through the Cliffhouse sandstone-siltstone which <br />overlies the Menefee. Cliffllouse surface waters apparently do not <br />migrate vertically and contribute to the ground waters of the Menefee. <br />Also omitted was tl~c contribution from Coal Gulch and its tributary <br />• -26- <br />
