<br />2.2,6.2 Fishery Facilities - The Intake structure and trashracks are <br />designed such that velocities will range from 2 to 3 feet per second <br />(0.6 to 0.9 m/s). Velocities a few feet from the trashracks will be <br />negligible In order that fish would not be drawn through the Intake, <br />The stilling basin dlsslpator at the end of the outlet works would <br />Increase the dissolved oxygen below the dam which may benefit <br />downstream fisheries. <br /> <br />2.2,6.3 Add I t lona1 Mlt Igat Ion Measures - Add I t lona1 discuss Ion on <br />mitigation measures as It relates to environmental Impacts Is <br />contained In Chapter 5. <br /> <br />2.2.7 Comparative Cost <br /> <br />2.2.7.1 The estimated annual cost In 1980 dollars per acre-foot less <br />engineering and construction management for Alternative A would be <br />$102. Appendix A shows the construction cost estimate breakdown In <br />1980 dollars for all alternatives. Operational cost Including <br />maintenance and replacement are estimated to be $20,000 per year and <br />would be the same for all reservoir alternatives. <br /> <br />2.3 ALTERNATIVE B: Larger Dam at Taylor Draw; Crest El. 5345 <br />(1629 m) <br /> <br />2.3.1 Location and General DescrIption <br /> <br />2.3.1,1 A larger dam at Taylor Draw would be located along the same <br />axis as Alternative A. <br /> <br />2.3.1.2 The capacity of the reservoir would be 27,400 acre-feet <br />(33.8x106m3) at the nonna1 high water line elevation of 5335 feet MSL <br />(1626 m), The surface area of the reservoIr at the high water line <br />(spillway crest) would be approximately 925 acres 074 ha). A dead <br />6 3 <br />pool storage volume of 2100 acre-feet (2.6x10 m) would Inundate <br />approximately 257 acres (104 ha) at an elevation of 5290 feet MSL <br /> <br />18 <br />
