(JU(1911 ., i.t HOMESTAKE DIVERSION PROJECT The Homestake Diversion Project is a municipally owned transmountain diversion project. The purpose of the project is to divert water from the headwaters of the Eagle River basin on Colorado's western slope for municipal use by the Cities of Colorado Springs and Aurora in the Arkansas River basin (Division 2) and the South Platte River basin (Division 1), respectively, The primary storage feature of the Homestake Diversion Project in the upper reaches of the Arkansas River basin is Turquoise Lake, constructed by the USBR as part of the Fryingpan-Arkansas Project, Project features in the Eagle River basin, which are the primary concern of the CRDSS Water Rights Planning Model, include: (a) the Missouri Tunnel, (b) Homestake Reservoir, and (c) the Homestake Tunnel. Each of these Project features is described in more detail below. The Homestake Diversion Project diverts available streamflow pursuant to various direct flow water rights from the East Fork and Middle Fork of Homestake Creek, as shown in the attached Figure H-1. Water is also diverted from French Creek, Fancy Creek, Sopris Creek and Missouri Creek via pipeline and is delivered through the Missouri Tunnel (WDID 374643) to storage in Homestake Reservoir (WDID 373516), located on the Middle Fork of Homestake Creek, All flows diverted into the reservoir can also be stored under a storage water right. Homestake Reservoir storage water is conveyed via Homestake Tunnel (WDID 374614) to Turquoise Lake located in the Arkansas River Basin, DESCRIPTION OF PHYSICAL FACILITIES The following discussion provides a brief description for the physical facilities pertinent to the western slope operations of the Homestake Diversion Project. Missouri Tunnel (WOlD 3746431 - The Missouri Tunnel is used to transport diversions from French, Fancy, Missouri and Sopris Creeks to Homestake Reservoir. The 8.0 ft. diameter tunnel extends approximately 1.6 miles through a mountain and has a rated capacity of at least 600 cfs, The diversions at each of the individual tributaries are measured and recorded by the City of Colorado Springs. Homestake Reservoir (WOlD 3745161 - Homestake Reservoir is located on the Middle Fork of Homestake Creek, southeast of the Holy Cross Wilderness Area, The reservoir has a total capacity of about 43,092 acre-feet of which 211 acre-feet is dead and inactive storage. At its normal high water line, the water surface area of the reservoir is about 334 acres. The reservoir stores all water diverted at the collection facilities on French Creek, Fancy Creek, Sopris Creek, and Missouri Creek and which are conveyed through the Missouri Tunnel. Inflows from the Middle Fork Homestake Creek and diversions from the East Fork Homestake Creek are also stored in the reservoir. H-1 3-1:,-%
