Water Demands/Water Rights Powderhorn Metropolitan District provides water and sanitary service to the existing Powderhorn Ski Area and surrounding commercial and residential community. The District is in the process of implementing a long-term strategy for water supply development to serve up to 2000 EQR of demand. See reports prepared by Wright Water Engineers dated October, 1984 and November 20, 1986, and by Western Engineers, Inc. dated July 25, 1985. Also refer to Water and Wastewater Facility Assessment by Resource Engineering, Inc. dated November 2, 1995 and the amended official development plan included in Exhibit C. The existing, and much of the future, water supply for the District is derived from junior diversions from the Big Beaver Creek drainage, in which the District is located. Two augmentation plans were adjudicated in the late 1980's to confirm a reliable legal supply from these sources per decrees entered in 85CW595 and 86CW015. Under these plans, the District is required to deliver its augmentation water to Mesa Creek at its confluence with Big Beaver Creek. The primary sources of augmentation water consist of (a) various senior irrigation rights on Mesa Creek, and (b) water stored in Robbins Reservoir, located on Big Beaver Creek. A reservoir was previously constructed and operated on the site of Robbins Reservoir, but the existing dam has been breached in several locations, and the original water right abandoned. The District holds two decrees for Robbins Reservoir, summarized below, and has received a ruling in Case No. 95CW352 which will allow water from various sources to be exchanged into Robbins Reservoir. Exhibit B includes copies of Water Court Case No. 85CW595 and Case No. 95CW352. 7
