<br />n <br />; <br /> <br />. <br /> <br />. <br /> <br />~ <br />J <br /> <br />Water can be released from any of the three reservoirs into a 24-inch <br />pipeline to the Northfield storage system on West Monument Creek. From turn- <br />outs on this (24-inch) pipeline, water can be diverted to the towns of Green <br />Mountain Falls and Chipita Park, or through a 30-inch pipeline to the penstock <br />of the Manitou powerplant. <br /> <br />A second 20- to 24-inch pipeline conveys water from the three North Slope <br />reservoirs to the afterbay of the Manitou powerplant. This line also inter- <br />cepts the flow of North and South Cascade Creeks and French Creek. Turnouts <br />from this pipeline can direct water to the towns of Cascade and Manitou <br />Springs. <br /> <br />The Northfield watershed (fig. 10) is located on the Rampart Range <br />northwest of Colorado Springs. The Northfield watershed produces only a minor <br />proportion of Colorado Springs water supply locally, but the reservoirs are <br />important for regulating water from other sources. The three Northfield <br />reservoirs--Rampart, Nichols, and Horthfield--have a combined capacity of <br />41,748 acre-feet, 40,886 acre-feet of which is in Rampart Reservoir~ Water <br />from the 48-inch Homestake pipeline enters the Northfield watershed through <br />Rampart Range tunnel 2, which discharges into Rainbow Gulch. Water conveyed <br />by the Homestake pipeline usually is water from the upper Arkansas basin via <br />Trout Creek which is Homestake, Fryingpan-Arkansas, or Twin Lakes Project <br />water; but the capability exists to divert Blue River water into Rampart <br />Reservoir at the divide pumping station. North Slope water enters the North- <br />field system through a 24-inch pipeline in Rampart Range tunnel I and flows <br />into Nichols Reservoir. <br /> <br />Water from Rampart Reservoir flows thcough a 42-, 36-, and 30-inch pipe- <br />line to the Pine Valley water-treatment plant. Water from this line can be <br />diverted to the Northfield Reservoir. Water also can be released. from Rampart <br />Reservoir downstream to Nichols Reservoir. Water from Nichols Reservoir is <br />discharged to Horthfield Reservoir by channel flow. Northfield Reservoir <br />supplies the Northfield water-treatment plant. (Stanley Canyon Reservoir, <br />Reservoir No.2, is no longer a part of the Colorado Springs system; it has <br />been leased to the U.S. Air Force Academy.) <br /> <br />The Penrose-Rosemont watershed (fig. II) is located southwest of Colorado <br />Springs on Gold Camp Road. Rosemont Reservoir, with a capacity of 2,538 <br />acre-feet, is located on East Beaver Creek. Water also is diverted from Gould <br />Creek to a 20-inch pipeline inside Rogers Tunnel. From Rosemont Reservoir, <br />water is transported through a 10-inch pipeline to Fisher Canyon and Penrose <br />Reservoirs, or to the Broadmoor water-treatment plant. <br /> <br />About 5 percent of the water consumed annually by Colorado Springs comes <br />from local streams, including Fountain Creek, Bear Creek, North and South <br />Cheyenne Creeks, and Sutherland Creek (fig. 12). Water is pumped from Foun- <br />tain Creek at the 33rd Street pumping station. Four pumps in this station <br />boost the water through a 20-inch pipeline to the Mesa water-treatment plant, <br />about I~ miles to the northeast. Water from Sutherland Creek no longer is <br />diverted directly from that creek but now is diverted from Fountain Creek at <br />the 33rd Street pumping station. <br /> <br />17 <br />
