-' . . ., - \. 083.4 December 28, 1976 Revised 12/29/76 FRYING!' ^N-AI~:ANSAS PROJECT Description and Operation 'l'he Fryingpan-Ark.lnsas Project consists of facilities on both the west' and cast slopes of the Colorado Rockies. . The west slope facilities consist of a water collection system located in .the Hunter Creek and Fryingpan River drainage basins, both of \-1hich are tributaries of the Roaring Fork River. The collection system is designed to divert water from various rivers and creeks in the two drainage basins and carry the water to the Charles H. Boustead Tunnel which then conveys the ,,,ater 'through the divide to the Arkansas Rivcr Basin. The t.otal collection system is designed to transport an average of 69,200 acre-feet of project water annually from t1.~ two drainage basins. The collection system is divided into two parts - Northside and Souths ide Collection Systems. The Souths ide System diverts and transports 50,800 acre-feet annually (or 73% of the total). The Hunter Creek drainage basin provides a portion of the water for diversion and transportation by the Souths ide System. These facilities are located on Hunter, No Name, and Hidway Creeks and fur!lish 16,8DO acre-feet annually or about 24~ of the total project water supply. Project Operating Prindp'les adopted by the State of Colorado and incorporated as a part of House Document No. 130, 87th Congress, 1st Session established minimum stream flows to protect existing and future beneficial uses of water in Western Colorado, including recreational and fishing values. The operating principles established minimum flows for all west slope ,lrainages except the Hunter Creek drainage. Those principles provide for release of 3,000 acre-feet annually to the head- waters of the Roaring Fork River for flow augmentation during low flow periods, from supplies that would otherwise be diverted by the Twin Lakes Canal and Reservoir Co~pany to the east slope. Although the operating principles do not address the subject of minimum flows in the Hunter Creek drainage. the Fish and wildlife Scrvic~ has recc~ended such flows and the Bureau has incorporated these flows in the Fryingpan River Project Operations. They provide minimum flows as follows: 3 ftis ft3/s ft /s Hunter Creek Midway Creek No Name Creek 8.5 2.5 3.0 The flows are enumerated and discu"sed in the Final Environmental Sta tement. Construction Status The first contract on Hunter Tunnel consisted of excavation for approximately 4.5 miles of tunnel from Chapman Diversion to Hunter Diversion, exc3vation for HUIlter Diversion illtakc shaft, access road construction to the outlet portal at the Chapman Diversion and Sawyer Creek conduit. This contract ','as completed in August 1973. j(:. .
