Given a final surface acreage of about 2,000 acres, the District will have acquired <br />approximately 3,000 ac-ft of water that can be extracted annually from the four principal <br />Denver Basin bedrock aquifers. Since there will be no demands associated with the ground <br />water beneath these undeveloped parcels, this Denver Basin ground water will serve as a <br />supplemental supply to the District's water supply portfolio. <br /> <br />There are several ancillary facilities that will also be completed on the reservoir site and <br />between the reservoir site and Cherry Creek to divert Cherry Creek flows into Rueter-Hess <br />Reservoir. Since Rueter-Hess Reservoir will store raw water, a water treatment plant is <br />planned near the northeast corner of the reservoir site (Figure 3). This water treatment plant <br />will process raw water from the reservoir, and then deliver these potable supplies into the <br />District's distribution system. <br /> <br />Water will be delivered to Rueter-Hess Reservoir from Cherry Creek by a surface-water and <br />a ground-water diversion system. The alluvial wells, diversion structures, pumps, and <br />pipelines are described below as the points of diversion for the water rights adjudicated on <br />Cherry Creek. <br /> <br />HISTORICAL RESERVOIR DEVELOPMENT STUDIES <br /> <br />In 1985, John C. Halepaska and Associates, Inc. (JCHA), as the hydrologic consultant to the <br />District, prepared a report which showed that the District would face a 3,000 ac-ft shortfall <br />at ultimate development based on the then-current District master plan, and the District's then- <br />adjudicated water rights. That report set in motion a series of studies which has resulted in the <br />development of Rueter-Hess Reservoir. <br /> <br />To evaluate how the District could overcome its water supply shortfall, JCHA did a subsequent <br />study on various water supply alternatives. One of these alternatives was to build an upstream <br />storage vessel on Cherry Creek that would capture in-priority Cherry Creek flows. This study <br /> <br />561Ii.Dec-rpt <br /> <br />-3- <br />
