E. Eyrich, Consulting Engineer, November 4, 1965.. This study in- <br />dicated: <br /> <br />Spillway would need to be designed to take a 63,000 c.f.s. flow and total <br />repair of structure was estimated at $459,050.00. <br /> <br />If a drop inlet at old outlet with adequate flows for 63,000 c.f.s. flood <br />the repair cost would be $611,000.00 <br /> <br />Analysis of Potential <br /> <br />Under favorable conditions the reservoir could fill in 10 months, however, <br />on basis of the average monthly flow and average evaporation rates, a period <br />of 32 months (2~ years) would be required to fill reservoir. In the event <br />of minimum stream flow and maximum evaporation conditions, this reservoir <br />would not develop a conservation pool of any magnitude and could be expected <br />to be completely dry throughout the major portion of the year. <br /> <br />Recreation potentials under this situation could be extremely erratic at <br />best. While the recreation need in the area is severe, serious consideration <br />of expenditures for recreation development should be made primarily where <br />continuous and year-around activities can be insured. The hit-or-miss basis <br />of inflows for Setchfield Lake, as well as the high evaporation rates (70% <br />-per-year); greatly limits the practical'"value of this impoundment. - - - - <br />
