and 6 V2 priority on the Poudre, allow Greeley to divert water in all but the most extreme dry <br />years. <br />Other Poudre basin rights include storage rights in five high mountain reservoirs: Barnes <br />Meadow, Peterson, Comanche, Hourglass, and Twin Lakes. The reservoirs capture water at high <br />elevations from some of the Poudre River's tributaries. High mountain storage is ideal because it <br />decreases evaporation, adds options for delivery, and obviates the need for mainstream dams. <br />However, Greeley's high mountain reservoir storage rights are junior and have low yields in <br />drought years. <br />Milton Seaman Reservoir, on the Poudre River's North Fork, is the City's largest multi- <br />year storage vessel within the Poudre basin. Milton Seaman Reservoir is primarily used as a <br />drought storage vessel and in most years remains relatively full with about 5,000 acre feet of <br />available water supplies. <br />A majority of Greeley's Poudre River water rights are treatable at Bellvue. However, <br />some of Greeley's Poudre River water rights cannot be physically delivered to Bellvue and are <br />therefore categorized as "untreatable." For example, Greeley's ownership in the Greeley <br />Irrigation Company (GIC" or the "No. 3 Ditch) represents an untreatable supply located in the <br />lower portion of the Poudre basin. These supplies are located too far downstream for treatment <br />and thus are used for non- potable irrigation of Greeley's parks and golf courses. This reduces <br />the amount of treated water used by the City. <br />Greeley also owns, or is in the process of acquiring, additional storage in the Poudre <br />Basin to store both untreatable and treatable supplies. These storage facilities will provide <br />additional firm yield and operational flexibility. For example, the " Poudre Ponds at Greeley" are <br />lined gravel pits located near the City that reuse, not physically but via river exchange, waste <br />water effluent (effluent). Greeley reuses, by river exchange, all its effluent that is legally <br />available for reuse to meet augmentation, non- potable, and return flow obligations. Full <br />utilization of effluent water is an important element of efficiently utilizing Greeley's total water <br />portfolio. <br />Colorado River <br />Greeley also obtains water from two interrelated transmountain diversion projects — the <br />Colorado -Big Thompson (C -BT) and Windy Gap projects. Raw water from these projects can <br />be delivered to either of Greeley's two treatment plants. <br />The C -BT Project provides supplemental water to its service area in northeastern <br />Colorado. The project boasts 800,000 acre feet of active storage and a relatively senior water <br />right on the Colorado River. Owned by the U.S. Bureau of Reclamation, it is operated by the <br />Northern Colorado Water Conservancy District (NCWCD). With 22,522 units, Greeley is one of <br />the largest municipal holders of C -BT rights. <br />The Windy Gap Project, was planned and built between 1969 and 1985.
