The reservoirs would be cooperatively developed by West Divide and the property <br />owners, and would supply water for agricultural uses, domestic uses, and instream flow uses within the <br />Crystal River watershed (Attachment A). <br />It is our understanding that West Divide was recently awarded $40,000 from the Colorado River Basin <br />Account for the project. These funds are available through the Colorado Water Conservation Board <br />(CWCB) Water Supply Reserve Account. Further, we understand that matching funds totaling $15,000 <br />will be contributed by West Divide. <br />STUDY BACKGROUND <br />The Crystal River is over-appropriated. Natural water supplies are in-sufficient to satisfy irrigation, <br />residential, and instream flow demands. The lower portion of the river is commonly dry during late <br />summer. Many existing residential water users located in un-incorporated areas do not have a legal water <br />supply. <br />West Divide currently provides augmentation water to about 20 existing water users in the Crystal River <br />watershed, extending from locations near the Town of Carbondale to above the Town of Redstone. This <br />regional augmentation program was adjudicated by the Water Court in Case No. 99CW320 and has <br />historically used water from Ruedi Reservoir to augment the out-of-priority depletions of its customers. <br />Augmentation contracts for these contractees were granted prior to 2004, at a time when the Colorado <br />718 Cooper Avenue Glenwood Springs, CO 81601 Phone (970) 945-2237 Fax (970) 945-2977 <br />
