<br />. <br /> <br />Municipal Systems <br /> <br />The complex water-collection systems of four municipalities in the area <br />are described herein: Colorado Springs, Pueblo, Trinidad, and Walsenburg. <br />Other major communities in the basin obtain their water directly from the <br />river or from nearby well fields. Lamar obtains a part of its supply from a <br />well field located in the flood plain of Clay Creek; this well field is par- <br />tially recharged with water delivered through Lhe Fort Bent Canal. <br /> <br />City of Colorado Springs <br /> <br />Unlike most cities of its size, Colorado Springs is not located on a <br />major stream that can be used for a direct source of water supply; therefore, <br />the city must rely on a complex system of sources for its water. Despite its <br />location, the city has developed resources capable of producing an average <br />annual water supply of 123,200 acre-feet, of which 52,400 acre-feet are <br />considered potable. In addition, future planned development will produce an <br />additional 56,200 acre-feet per year, resulting in an annual water supply of <br />179,400 acre-feet.' <br /> <br />. <br /> <br />The raw water supply developed for the city is from a combination of <br />sources that is outlined in table 1 and shown in figure 6. Volumes and <br />percentages for 1982 from each source also are listed in table 1. The 1982 <br />figures do n~t include reuse and are not necessarily typical of future llse. <br />Plans for future development include. an expansion of the Homestake collection <br />system (Homes take Project, Phase II) and the Eagle-Arkansas Project, which are <br />both transmountain diversions from the Colorado River basin into the Arkansas <br />River basin. <br /> <br />The mountain collection system (fig. 7) consists of the Pikes Peak water- <br />shed, the Northfield watershed, and the Penrose-Rosemont watershed. The Pikes <br />Peak watershed is further divided into the South Slope watershed and the North <br />Slope watershed. An average annual water supply of about l6,400 acre-feet is <br />produced from the mountain collection system and 3,200 acre-feet from local <br />streamflow. The South Slope watershed (fig. 8) is located on the south side <br />of Pikes Peak, southwest of the city. It consists of 7 reservoirs with a <br />combined capacity of 6,862 acre-feet that intercept flow from the drainage <br />basins of 11 streams. Water is transported through a series of channels, <br />tunnels, and aqueducts to city water-treatment plants. Enroute, the water <br />generates electrical power at two sites. <br /> <br />The outermost area of the South Slope watershed is the East Fork West <br />Beaver Creek, including Bighorn and Wilson Reservoirs. Water is diverted from <br />the East Fork West Beaver Creek through the Strickler Tunnel to Boehmer Creek <br />in the Middle Beaver Creek basin. The water from this basin is regulated by <br />Boehmer, Mason, and McReynolds Reservoirs. Mason and McReynolds Reservoirs <br />are connected by a 20-inch pipeline. <br /> <br />. <br /> <br />IMcCullough and Miskel, 1974, and Edward Martinez, Colorado Springs <br />Department of Utilities, oral and written communs., 1983. <br /> <br />1l <br />
