<br />,-. Similarly, the alternative conveyance routes were evaluated to determine the more favorable <br />route for future consideration. No environmental factors were discovered which would preclude <br />further consideration of the conveyance routes, <br /> <br />Reservoir Sites Eliminated <br />Three reservoir sites were eliminated based on the findings of the initial screening and one <br />site location was modified, <br /> <br />- <br /> <br />The Haypark Site was eliminated due to the small potential reservoir yield, Preliminary <br />hydrologic analysis estimated a potential yield in the range of 10,000 to 12,000 af/yr. <br /> <br />The Lower Piney Site was eliminated because of the high potential for reservoir seepage due <br />to the existence of permeable lenses within the bedrock in the reservoir area and at the dam axis, <br /> <br />The Iron Mountain Site was also eliminated due to potential reservoir seepage, The <br />Homestake Shear Zone could allow significant seepage through the ridge to the adjacent Eagle River <br />canyon. <br /> <br />The Wolford Mountain Site A location was modified due to questions about the stability of the <br />right abutment. Site A', 3800 feet upstream, was substituted for Site A. These geotechnical <br />questions are not a concern at Site A'. <br /> <br />,.... <br /> <br />Reservoir Sites Selected <br />The following reservoir sites were selected for further analysis: Red Mountain, Wolford <br />Mountain A', Wolford Mountain C, Azure, Wolcott (both higher and lower dams) and Una, Table 2.1 <br />,- presents the reservoir sites and capacities designated for reconnaissance-level evaluation, The <br />minimum pool shown represents the lowest reservoir content after all usable water is released, It <br />was based on either the assumed structural minimum (such as the elevation of the inlet to the outlet <br />works) or the allowance reserved for sediment accumulation. <br /> <br />2-5 <br />
