Figure 1. This system utilizes the C-BT Project facilities but the Windy Gap Project water is <br />administered separately from the C-BT Project water, as discussed in the Operational <br />Information section. <br />After its formation, the Subdistrict negotiated a Carriage Contract with Reclamation and <br />NCWCD specifying how Windy Gap water would be stored and carried to the Eastern Slope <br />cities through the C-BT Proj ect facilities. The Carriage Contract executed in October 1973 was a <br />crucial first step in the development of the Windy Gap Project. With the ability to use excess <br />capacity of the existing C-BT Project's storage and conveyance facilities, the Windy Gap Project <br />was economically and environmentally viable. <br />In the summer of 1975 the Subdistrict entered into water allotment contracts with six cities <br />located along the Front Range -Boulder, Longmont, Loveland, Fort Collins, Greeley and Estes <br />Park. Each retained aone-sixth share in the Windy Gap project, although many have since <br />transferred portions of their individual allotment. There are now 13 owners of Windy Gap units <br />(i.e., shares). Allotment contracts provide that participants annually receive their proportional <br />share of Windy Gap water. Every unit equals approximately 100 ac-ft of water, or 1/480th of the <br />average annual quantity of water pumped from the Windy Gap Reservoir and stored in Lake <br />Granby. <br />The 1980 Windy Gap Settlement Agreement provided mitigation measures for the Project. The <br />Division 5 Water Court then granted conditional decrees totaling 600 cfs for the Windy Gap <br />Project on October 27, 1980. That quantity was confirmed in a final absolute decree nearly a <br />decade later following construction and operation of the Windy Gap Project. <br />East Slope Distribution System <br />The C-BT Project's East Slope distribution system facilitates the storage and delivery of Project <br />water within NCWCD boundaries, as shown in Figure 1. Although accounted for separately, C- <br />BTProject water and Windy Gap Project water are delivered to the respective eastern slope <br />allottees together. After water exits the East Portal of the Adams Tunnel, it is used to generate <br />electricity, dropping almost ahalf--mile through five power plants to the Front Range. The <br />Western Area Power Administration (WAPA) oversees the contracting and sale of the <br />hydropower which helps pay a considerable portion of the Project's cost. <br />Water is stored in three terminal Front Range reservoirs and released to farmers, industries and <br />municipal allottees upon request. The District provides agricultural water deliveries between <br />April and October, the primary growing season. Municipal and industrial users generally may <br />request delivery of water year-round. <br />The Project's principal East Slope storage reservoirs are Horsetooth Reservoir and Carter Lake. <br />Boulder Reservoir (0604515) is filled from Carter Lake via the Boulder Feeder Canal. <br />Horsetooth Reservoir primarily serves northern portions of the District, while Carter Lake and <br />Boulder Reservoir supply the District's southern reaches. Like the Project's West Slope <br />Collection System, the C-BT's East Slope reservoirs also provide flat-water recreation and <br />scenic beauty. <br />8of17 <br />
