343'{ (b) Name And Qualifications Of Person Responding To The Regulation; Harold E. Miskel Manager, Resource Planning & D~velopment, City of Colorado Springs Department of Public Utilities, and Chairman, Homestake Steering Committee (5) Scope Of Proposal: (a) Provide Detailed Engineering Plans And Specification Of Proposal Including Proposed System Capacity And Service Area Plans; Plans and specifications are Attachment 6. Service areas for both Colorado Springs and Aurora are approximately the same as city boundaries. City boundary maps can be found in Attachments 7 and 8. (b) Provide A Description Of All Existing Or Approved Proposed Systems Within The Development Area And Source Development Area; Except for a small portion of Homestake Reservoir, the Homestake I collection system lies entirely within Eagle County. Several East Slope counties are spanned by the delivery systems to Colorado Springs and Aurora. The existing Homestake Phase I consists of diversion points at East Fork Homestake, mainstem Homestake, Missouri, Sopris, French and Fancy Creeks. Additionally, Homestake Reservoir with constructed storage capacity of approximately 45,000 acre feet is West Slope storage for waters diverted from the headwaters of Homestake Cr~ek and its tribu- taries. Diverted water, except for mainstem Homestake, is delivered to Homestake Reservoir via a system of pipelines and the Missouri Tunnel. The five and one-half mile long Homestake Tunnel, connecting Homestake Reservoir under the Continental Divide with Turquoise Reservoir, provides delivery capability to the East Slope. The streamflow in Lake Fork Creek is limited to 300 cubic feet per second (cfs) by an agreement with the Forest Service to prevent streambank erosion; therefore, the flows through the Homestake Tunnel are limited to the difference between 300 cfs and the actual native flow in Lake Fork Creek. Homestake water is transported from Turquoise Reservoir through the Mt. Elbert Conduit and the Mt. Elbert Pumped Storage Power Plant, where the water generates electricity and then is stored in Twin Lakes Reservoir. Presently, Homestake water is released from Twin Lakes Reservoir to the Arkansas River where adequate channel capacity exists, and is subsequently pumped from the river at the Otero Intake, approximately 6 miles downstream. In the future, the Otero Intake pipeline will be extended to the dam outlet works at Twin Lakes Reservoir, shown in red on Attachment 9. This improvement is expected to be completed by 1985, and will eliminate the use of the Arkansas River to transport Homestake water. The Otero Pump Station pumps the water through the 66-inch Homestake pipeline to the bifurcation point located in South Park. At the bifurcation point, Aurora's water flows through six miles of open channel to Spinney Mountain Reservoir, shown on Attachment 10. From 5
