Exhibits 1 and 2 show the precipitation and pan evaporation at Meredith, Colorado, near
Ruedi Reservoir. Table 2 and Exhibit 3 depict the monthly operation of the reservoir
during water year 2001.

B. West Slooe Collection Svstem and Proiect Diversions

The import of Project water through the Boustead Tunnel began on April 26, 2001, and
concluded on August 23,2001. The daily discharge record forthe diversion structures is
included as Appendix D. A total of 45,300 acre-feet was imported during the 2001 water
year, which was 70 percent of average. There was no Busk-Ivanhoe water imported
through the Boustead Tunnel. The maximum mean daily import was 743 ft'/s on June 2,
2001. The most probable forecasts for the first of February, March, April, and May were
48,600 acre-feet, 46,600 acre-feet, 46,100 acre-feet, and 52,800 acre-feet, respectively.

The total imports for the water year, the accumulated imports to the Arkansas River, the
water used for the Twin Lakes Reservoir and Canal Company exchange, and the import
water available for allocations by the Southeastern Colorado Water Conservancy District,
are shown on Table 5. The 30 years of accumulated imports totallA87,500 acre-feet,
for an average of 49,583 acre-feet per year. A plot of the Boustead Tunnel imports
during water year 2001 is shown on Exhibit 5.

C. Twin Lakes Reservoir and Canal Comoanv/FrvinQoan-Arkansas Proiect
ExchanQe

The Bureau of Reclamation is obligated to maintain minimum streamflows in the Roaring
Fork River by the authorizing legislation of the Project. This is accomplished through an
exchange of water with the Twin Lakes Reservoir and Canal Company. On October I,
2000, the company began bypassing water into the Roaring Fork River on the West Slope
in exchange for Project water stored in Twin Lakes on the East Slope. The exchange was
performed per the operating criteria as shown in Appendix C. The total amount of the
exchange at Twin Lakes Reservoir was 2,146 acre-feet. The monthly summary of the
exchange is also shown in Appendix C.

D. Turauoise Lake

On September 30,2000, there were 110,230 acre-feet (elevation 9858.47 feet) of water
stored in Turquoise Lake, which was 113 percent of average. Releases to Twin Lakes
through the Mt. Elbert Conduit drafted Turquoise Lake to 49,114 acre-feet (elevation
9817.97 feet), the lowest storage of the water year, by March 16, 2001. There were
106,462 acre-feet (elevation 9856.21 feet) of water in storage at the end of the water
year, which was 109 percent of average.
