<br />not considered likely. Some adjustments in diversion operations could <br /> <br /> <br />reduce hydrologic impacts to the wetlands but could also reduce the <br /> <br /> <br />safe yield. <br /> <br />Institutional Issues <br /> <br />Clarification of required permits and resolution of any mitigation <br /> <br />requirements are needed. The existing diversion is currently permitted <br /> <br />by the COE. Final resolution of the status of water rights by the <br /> <br />Water Court is necessary. <br /> <br />EAST GORE COLLECTION SYSTEM <br />The East Gore collection system would collect and divert water <br />from tributaries of the Blue River and convey the water by gravity to <br />Dillon Reservoir. The water would be conveyed from Dillon Reservoir <br />through the Roberts Tunnel to increase the safe yield of the Denver <br />water supply. The pressure gravity system would consist of a 4,800- <br />foot-long tunnel section, 23.4 miles of conveyance pipeline, 29.4 miles <br />of collection branch pipeline, 31 creek diversion' structures, and an <br />outlet works at Dillon Reservoir. <br /> <br />The 4, 800-foot-long tunnel sect ion would be used at the beginning <br />of the conveyance system to avoid construction of the main pipeline <br />along the rugged cliffs in the Cataract Creek area. The conveyance <br />pipeline would extend from the tunnel outlet to Dillon Reservoir. The <br />inverted siphon sections, used to cross the lower reaches of the Black, <br />Slate, and Boulder Creeks downatresm from the existing landslide areas <br />and to cross the Blue River downstream from Dillon Reservoir, would be <br />designed for pressure flow. The proposed pipeline alignment avoids <br />unfavorable geotechnical and topographic condit Ions, while maintaining <br />a relatively constant slope between the two adjacent inverted siphon <br /> <br />13 <br />
