<br />Metropolitan Water Supply Investigation <br /> <br />MWSI Results <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />Most of Aurora's changed irrigation rights were formerly used to irrigate ranches in the <br />South Park area of the Upper South Platte. Aurora's South Platte municipal rights are <br />associated with its Spinney Mountain Reservoir and its intake, at Strontia Springs. <br />Aurora's transbasin supplies include its diversions from its interests in the Homestake, <br />Twin Lakes and Busk-Ivanhoe projects, and its acquired agricultural water rights from <br />the Arkansas River Basin, principally its Rocky Ford Ditch and Colorado Canal rights. <br />Aurora's supplies derived from water reuse include its effluent exchanges from the Metro <br />wastewater plant to its upstream points of diversion and storage, direct reuse on several <br />parks and golf courses, and augmentation of its Cherry Creek alluvial wells. Aurora uses <br />a small amount of its Denver Basin groundwater resources for irrigating parks and golf <br />courses and for reservoir evaporation replacement. Aurora's policy on development of <br />Denver Basin groundwater is to reserve their primary use for drought protection. <br />Aurora's water conservation efforts include a water conservation-oriented rate structure <br />and several educational and voluntary programs. <br /> <br />3.1.5.4. Northeast Metro Sub-Region <br /> <br />The Northeast Metro sub-region includes Thornton, South Adams County Water & <br />Sanitation District (SACWSD) and Brighton, The water supply sources currently <br />available to this sub-region include municipal and changed irrigation rights on the South <br />Platte and Clear Creek, alluvial and nontributary wells, and exchange rights. <br /> <br />Thornton owns shares in several upper and lower Clear Creek irrigation companies as <br />well as in the Standley and Barr Lake divisions of the Fanners Reservoir and Irrigation <br />Company (FRICD). Thornton's municipal rights are centered around its East and West <br />gravel lakes facilities located near the Burlington Ditch headgate. Thornton also has <br />several important exchange rights between the Metro wastewater plant and its diversion <br />points on Clear Creek and at the Burlington Ditch. <br /> <br />SACWSD diverts most of its supplies from South Platte alluvial wells that are augmented <br />by SACWSD's water rights associated with the Burlington Ditch system. SACWSD also <br />uses a small amount of Denver Basin groundwater from its deep wells. SACWSD has <br />recently reached an agreement with Denver Water that will provide SACWSD with a <br />4,000 acre-foot treated water supply for partial replacement of and blending with its <br />tributary wells, which have experienced ongoing water quality problems. <br /> <br />Brighton diverts its supplies from alluvial South Platte wells that are augmented with <br />water from Brighton's shares in several South Platte Irrigation ditches. <br /> <br />Prepared for the Colorado Water Conservation Board.

Northwest Metro Sub-Region <br /> <br />The Northwest Metro sub-region includes Arvada, Broomfield, the Consolidated Mutual <br />Water Company, Golden, Northglenn, Thornton, Westminster and other small providers <br />in the Clear Creek basin.' <br /> <br />5 <br />While the City of Golden is discussed in the MWSI report for the purpose of providing a complete overview, it <br />should be noted that Golden did not participate in the MWSI process. <br /> <br />32 <br />
