Water and Wastewater Assessment by Resource Engineering, Inc., dated November 2, 1995. See Exhibit C The District is in the process of implementing a long-tenn strategy for water supply development to serve the demand of the District's Service Area. Refer to reports prepared by Wright Water Engineers dated October, 1984 and November 20, 1986, by Western Engineers, Inc. dated July 25, 1985 and by Resource Engineering, Inc., dated November 2, 1995. 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 confinn a reliable legal supply from these sources. See 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. Project Service Area/Site Description As shown by Exhibit A, the Robbins Reservoir site is located in Mesa County, Colorado at Powderhorn Resort; seven miles South of Mesa, Colorado on Colorado Highway 65 in the Northeast One Quarter of Northwest One Quarter of Section 20, TIIS, R69 West of the 6th P.M. The project service area is the Powderhorn Metropolitan District's I and II and other properties in the area which may be served. Exhibit A shows the property included in the Powderhorn Metropolitan Districts. The project service area is located on the Northern plains of the Grand Mesa. The general slope of the site is down to the North with gradients typically ranging from 10 to 30 6
