The <br />reservoir would be supplied from the mainstem by a 50 cfs gravity <br />feeder canal approximately 5.6 miles long. <br /> <br />o Site a - Located on Lewis Creek just above its mouth. The <br />reservoir would be supplied from the mainstem by a 50 cfs pump <br />station and conduit with a laO-foot lift. <br /> <br />o Si te 9 - Located on the mainstem just upstream of the confluence <br />of Whites Canyon. <br />These three sites are shown on Figure D-ll. <br /> <br />D.4.7 Competency of Sites <br /> <br /> <br />Reconnaissance-level evaluations of the three potential sites were <br /> <br /> <br />made using maps, published reports, and opinions of officials <br /> <br /> <br />knowledgeable of the area. No .field observations or site <br /> <br /> <br />investigations were made for this initial assessment of the cost of <br /> <br /> <br />providing'storage. . Evaluation of the general suitability of the <br /> <br /> <br />potential sites and the competency of foundations consisted of a <br /> <br /> <br />review of published literature concerning area geology, engineering <br /> <br /> <br />properties of bedrock and valley fill materials, landslide hazards, <br /> <br /> <br />seismicity, faulting, and potential sources of construction <br /> <br /> <br />materials for a dam. <br /> <br />22 <br />
