<br />, . <br /> <br />(8) Downstream problems. Downstream from Cherry Creek <br />Dam, the flood plains range from newly developed residential <br />areas to the older highly developed areas of the Denver business <br />and industrial district. Since the completion of the Cherry <br />Creek Dam in 1950, flood damages have been minimal. Deteriorating <br />channel conditions have reduced the capacity and the ability of <br />the channel to safely convey releases from the Cherry Creek <br />Reservoir. In addition, these conditions have reduced the <br />channel's capability to convey runoff originating downstream <br />from the Cherry Creek Dam. About 750 acres of land in the highly <br />developed areas of the flood plain are subject to flooding from <br />tributary inflow. Structures along Cherry Creek are in danger of <br />being either damaged or destroyed by channel erosion. Measures <br />are required to stabilize the channel during releases from the <br />Cherry Creek Reservoir and to increase the capacity of the channel <br />to carry tributary inflow. <br /> <br />~ <br />~. <br />,$i' <br /> <br />b. Water supply. Water supplies in the South Platte River <br />basin are overappropriated. Municipal and industrial users are <br />in direct competition with irrigation users. Water is imported <br />into the upstream reaches of the South Platte River basin to <br />augment the natural supply. In 1965, imported water represented <br />&bout one-third of the supply in Metropolitan Denver. In the <br />highly developed areas of the Cherry Creek basin, water supplies <br />are obtained from either the Denver Water Board or the Aurora <br />\later Board. These agencies obtain their supplies from wells <br />Yithin the Cherry Creek basin, from transmountain diversion, and <br />from the South Platte River basin surface supplies. In the <br />rural areas of the Cherry Creek basin, water supplies are obtained <br />from wells. As urban expansion moves southward in the Cherry <br />Creek basin, additional water will be required. \later yields in <br />the basin are insufficient to meet these future needs. Addi- <br />tional supplies Yill have to be imported and conservation <br />practices vill have to be followed to meet the expanding needs <br />of the baBin. <br /> <br />c. Recreation. The rapid population growth in the <br />Metropolitan Denver area vill create greater demands for <br />recreational developnent. In addition to the needs of the <br />local population, tourists will also create needs for recrea- <br />tional development. The scenic mountain areas Yill satisfy <br />some of these existing and future needs. The demands of an <br />increasing population vill require the development of recrea- <br />tiOnal facilities within relatively short commuting distances <br />of the population. These .facilities can be established at <br />either regional or local parks. The Denver Regional Council of <br /> <br />22 <br />
