Eagle-Vail Metropolitan District. The Eagle-Vail plan for augmentation was decreed in Case
No. W-3289. The replacement water sources include the historical consumptive use from
irrigation of 515.4 acres by ditches which historically diverted from Stone Creek (aka
Willow Creek), the Eagle River, Beaver Creek, Whiskey Creek, and an unnamed tributary of
the Eagle River. During the irrigation season, some of the historical consumptive use
replaces out-of-priority depletions and some is stored in Nottingham Lake, aka Benchmark
Lake, for release during the non-irrigation season to replace out-of-priority depletions. The
"future consumptive uses" covered by the plan for augmentation totals 647.8 acre-feet
annually and includes 200 acre-feet for golf course irrigation, 360 acre-feet for lawn and
landscape irrigation, 73 acre-feet for in-building household and commercial uses, and 14.8
acre-feet for Eagle-Vail's share of evaporation from Nottingham Lake. The historical
consumptive use was quantified as 824.4 acre-feet annually of which 647.8 acre-feet were
committed to the plan for augmentation. The Edwards Metropolitan District acquired 45
acre-feet of the historical consumptive use out of the uncommitted 176.6 acre-feet and
included these water rights in a plan for augmentation decreed in Case No. 92CW295. The
remaining 131.6 acre-feet are included in the pending Case No. 95CW348 and are
distributed monthly as shown in Table 2.

Town of Avon. The plan for augmentation for Avon was decreed in Case No. W-3664 and
modified in Case No. 84CW225. It was adjudicated by the Avon Metropolitan District
which formerly provided water service to the Town of Avon. However, all of the water
rights of the Avon Metropolitan District were recently conveyed to the Town. Avon's
"future consumptive use" was estimated to total 282.8 acre-feet annually of which 95.2
acre-feet were used for in-building residential and commercial purposes, 149.3 acre-feet
were used for lawn and park irrigation, and 38.3 acre-feet were used for Avon's share of
evaporation from Nottingham Lake. The out-of-priority depletions are replaced by historical
consumptive use and storage releases from Nottingham Lake. The historical consumptive
use was quantified as 448 acre-feet annually and was attributed to irrigation of 280 acres
by ditches diverting from the Eagle River, Buck Creek (aka Earnest Creek) and Beaver
Creek. The historical consumptive use can be used for replacement purposes or stored in
Nottingham Lake during the irrigation season, May 13 through October 10. During the non-
irrigation season, the out-of-priority depletions are replaced by releases from Nottingham
Lake. The difference between the historical consumptive use and the future consumptive
use can be exchanged to Eagle Park Reservoir as distributed in Table 2. By contract with
UERWA, this amount is limited to 123 acre-feet.

Beaver Creek Metropolitan District. Beaver Creek changed some relatively senior water
rights to domestic, commercial, and municipal uses and permanently withdrew from
irrigation other relatively senior water rights in Case No. W-2746. The changed water
rights are used at the Metcalf and Raw Water Booster Pump Headgates for Beaver Creek.
