Homestake Project water can be stored in Turquoise Lake, routed via ~h Mount Elbert conduit to Twin Lakes, or released down the Arkansas River t Otero pumping-plant intake. The city presently (l983) has a contract with e Fryingpan-Arkansas Project (fig. 6) for l5,000 acre-feet of storage space, and with CF&I Steel Corporation for an additional 4,000 acre-feet of storage space in Turquoise Lake. Homestake Project water, either from Turquoise Lake or Twin Lakes, is released into the Arkansas River, then to the Otero pumping-plant intake. An outlet structure is built into the new Twin Lakes Dam that eventually will convey Homestake Project and Twin Lakes Project water to the Otero pumping plant in a pressurized conduit, which will save about 350 feet of hydraulic head or required lift for the Otero pumping station. Routing Homestake Project water in this manner also makes it available to generate power in the Fryingpan-Arkansas Project's Mount Elbert powerplant., The Otero pumping plant supplies water to the 66-inch Homestake pipeline, which conveys it over Trout Creek Pass and across the lower end of South Park (fig. 6). The 66-inch pipeline has a bifurcation at a, point south of Spinney Mountain Reservoir. Here, Aurora's water is delivered to Spinney Mountain Reservoir and flows through that reservoir into the South Platte and on to Aurora. Colorado Springs' share of the water flows in a 26-mile long, 48-inch diameter pipeline to the Divide pumping plant. From there'it can be diverted to either Rampart Reservoir at Northfield (fig. 10), or through the Montgomery pipeline to the North Slope reservoirs (fig. 9). The town of Woodland Park receives an average of 225 acre-feet per yeilll from the Homestake pipeline. In exchange for this water, the Cherokee Wat~ District delivers a like quantity to the east side of Colorado Springs. The planned Eagle-Arkansas Project would intercept the waters of Cataract Creek and other headwater tributaries of the Eagle River and convey them, via Tennessee Pass, to Tennessee Creek in the Arkansas River basin. Colorado Springs expects to realize an annual supply of 2,700 acre-feet of water from this source. j The collection system of the Blue River Project is in the headwaters of the Blue River near Hoosier Pass, northwest of Fairplay, Colorado (fig. l4). This system consists of a series of diversion dams, conduits, reservoirs, and tunnels that intercept the headwaters of the Blue River and six tributaries. The diverted streams are the Blue River, Crystal Creek, Spruce Creek, McCullough Creek, West Hoosier Creek, and East Hoosier Creek. Storage in upper Blue Lake is 2,l20 acre-feet. Blue River Project water crosses the Continental Divide via the Hoosier Tunnel and is stored in the 5,lOO-acre-foot Montgomery Reservoir. From Montgomery Reservoir, the water is conveyed about 70 miles across South Park in the 3D-inch Montgomery pipeline. At the Divide pumping station, it is possible to divert Blue River water through the Homestake pipeline into Rampart Reservoir (fig. 10). Usually, however, the water is conveyed by the Montgomery pipeline to reservoirs on the North Slope of Pikes Peak. The average annual yield of the Blue River Project is l2,lOO acre-feet. . 22 ~
