<br />'0'00827 <br /> <br />ALTERNATIVE C <br /> <br />The most inexact portion of Alternative A and Alternative B is <br />the cost of tunneling under the Continental Divide to provide a passage <br />where water can pass from the collector system into Jack Creek. The <br />problems, costs, and hazards of tunneling are never completely identified <br />until the task is underway. To alleviate this uncertainty, the WWDC <br />considered alternate routes where water could flow by gravity from the <br />collector system across the Continental Divide without requiring a tunnel. <br />The route chosen in this alternative accomplishes this purpose. <br /> <br />During the course of this project it has been brought to the attention <br />of the Commission that the City of Rawlins not only requires additional <br />water Dut that an existing supply is in jeopardy due to the condition of <br />an old wooden supply line. The routing selected here will deliver the <br />water from the collector system to the North Platte River and will allow <br />Rawlins the option of replacing its old line by paying the cost of enlarging <br />the delivery line in this alternative. <br /> <br />More specifically, this alternative would deliver water by gravity from <br />the collector system to the upper end of Sage Creek. A regulating reservoir <br />would be constructed just downstream of the existing Rawlins Reservoir <br />which would be inundated by the new impoundment. A second delivery line <br />would be constructed from the new reservoir northward along the Sage Creek <br />Road to near the Atlantic Rim Reservoir. This section of pipe has been <br />designed and priced either to accommodate the projected Sage Creek supply <br />available to Rawlins or to carry only the imported water. From the Rawlins <br />Reservoir the delivery line would continue northeasterly past Sinclair and <br />on to the North Platte River near the confluence of Sugar Creek. <br /> <br />11 <br />
