Denver's excess reusable return flows, and treated water or raw water pipelines from Denver's <br />southern system. Denver may allow participation by other East and West Slope providers in its <br />North End project in order to address water supply and instream flow deficiencies in the Fraser <br />River and Boulder Creek basins. <br />Denver is also planning to develop a pump and pipeline facility from Chatfield Reservoir to its <br />existing raw water conduits. This project would allow Denver to make better use of its existing <br />water rights and storage pool in Chatfield. The Corps of Engineers and the CWCB are also <br />completing a study that could allocate as much as 20,600 acre -feet of existing Chatfield flood <br />control storage to municipal water supply purposes. (Currently, Denver Water has 10,785 acre - <br />feet of water supply storage in Chatfield.) Denver is also doing a feasibility study of developing <br />the Denver Basin groundwater beneath its service area as a back -up drought year supply. Other <br />providers in the central South Platte region are actively pursuing a range of storage projects and <br />reuse projects including Consolidated Mutual's Fortune Reservoir, enlargement of Standley <br />Lake, Clear Creek and South Platte gravel pit storage, and nonpotable reuse projects in the Big <br />Dry Creek basin. <br />c) South Platte Basin — Northern Portion <br />A wide range of major storage development efforts are being considered in the Northern Front <br />Range, centered around five goals: firming up the yield of the Windy Gap transbasin diversion <br />project, capturing excess return flows in the South Platte below Greeley, regulating acquired <br />irrigation rights for year -round municipal use, facilitating exchanges and capturing <br />unappropriated peak flows. <br />Potential projects under consideration for these purposes include enlargements of Halligan and <br />Seaman Reservoirs on the North Fork of the Poudre; new off - channel reservoirs adjacent to <br />Carter Lake (Chimney Hollow), south of Livermore (Glade Reservoir), north of Greeley <br />(Lonetree Creek), and between Granby and Willow Creek Reservoirs on the West Slope (Jasper <br />North); new mainstem dams on the Poudre and the Little Thompson Rivers; and new gravel pit <br />reservoirs along the Poudre. Most of these projects are being considered in various combinations <br />as part of the Northern Colorado Water Conservancy District's Windy Gap Firming Project, its <br />Northern Integrated Supply Project and its South Platte Water Conservation Project. Some <br />options are being pursued by individual providers. <br />In addition to developing new storage, northern Front Range providers continue to acquire South <br />Platte irrigation rights and CBT shares, develop water exchange and reuse projects, and construct <br />new raw water delivery pipelines to assure year -round water availability from CBT reservoirs <br />and to protect source water quality. Examples include the proposed Pleasant Valley Pipeline <br />which would run between Horsetooth Reservoir and the Munroe Canal, Lafayette's 75 Street <br />delivery pipeline from Boulder Creek, Broomfield's development of nonpotable reuse <br />capabilities in its developing service area, and a potential new pipeline from Carter Lake to <br />Boulder Reservoir designed to avoid potential water quality problems at the Boulder Reservoir <br />water treatment plant. <br />kr -1 <br />
