II' 1I1:i;)!} to the beneficiaries of the Summit County Agreement and created a surplus of 920 acre-feet, the rights to which were then conveyed to the Grand County users, including Winter Park. The 920 acre-feet of water is delivered in the form of a bypass at Denver's collection systems in the Fraser and Williams Fork basins. The "Bypass Water" is in addition to all other minimum flows that Denver had previously been required to bypass at the headgates of its Fraser River Collection system. To the extent that all of the 920 obligation is not bypassed and used by users in Grand County, r;>enver will release water from Williams Fork Reservoir to make up any shortage. In exchange for the 920 acre-feet, the Grand County water users must provide replacement water to Denver on the basis of 0.67 acre-foot for every acre-foot of "Bypass Water" released by Denver between September 15 and May 15 of the year and 1.33 acre-feet for every acre-foot released between May 1 6 and September 14. The source of replacement water is contract water in Wolford Mountain Reservoir purchased by Grand County water users and assigned to Denver. The Clinton Agreement also contains provisions for Summit County, the Town of Dillon, the Town of Frisco and Copper Mountain to reduce their respective entitlements to water from the original Summit County Agreement in exchange for water stored in Dillon Reservoir (" Future Dillon Reservoir Water") on the basis of one acre-foot in the reservoir for every acre-foot of reduction. The Future Dillon Reservoir Water can then be used as a source of year-round augmentation by any Summit or Grand County water user. In order to use this Future Dillon Reservoir Water, the user must provide replacement water to Denver on the basis of 1.58 acre-feet for every acre-foot of Future Water. The primary sources of this replacement water would be Green Mountain Reservoir, Wolford Mountain Reservoir or other sources acceptable to Denver, including Clinton Reservoir water itself. As of January 1996, the Town of Frisco had exercised this option and converted 100 acre-feet of its original Summit County Agreement water to Future Dillon Reservoir water (December 1994) and Copper Mountain had converted 97.3 acre-feet (November 1995). The Clinton Agreement provides that up to 343 acre-feet of water in Clinton Reservoir can be released for subsequent diversion by the Copper Mountain Ski Area (WOlD 361016). All return flows from this use (reservoir release less 20% consumptive use for snowmaking) is treated as a new supply to Denver and is credited against any consumptive use repayment water owed to Denver by anv other snowmaking user. The keystone Ski Area (WOlD 360908) can use its Summit County Agreement water or its Clinton water by an exchange on the Snake River providing that the instream flows on the Snake River are not adversely impacted. Otherwise, Keystone has the rights to divert directly from Denver's Roberts Tunnel (via the Montezuma Shaft) up to 1,500 acre-feet per year. To repay Denver, Keystone causes a release from Clinton Reservoir in an amount equal to 20% of its total diversion used for snowmaking (if the water is used for other purposes, the consumptive use is computed using factors referenced in the Agreement). The Town of Breckenridge may use its Reservoir Yield from Clinton Reservoir to exchange against out-of-priority storage in Goose Pasture Tarn. This exchange is made on an acre-foot for acre-foot basis and can only occur when the Computed Natural Inflow is greater than 50 cfs. The Breckenridge Ski Area can also exchange its Reservoir Yield from Clinton Reservoir to storage in Goose Pasture Tarn for subsequent snowmaking uses. Because of return flows from snowmaking, the Ski Area is obligated to release (or credit to Denver's account in Clinton Reservoir) only 0.2 0-13
