Cowlitz Falls Project No. 2833 - Washington
The Public Utility District No. 1 of Lewis County (Applicant), of Chehalis, Washington, proposes to construct a hydroelectric project with an installed capacity of 70 MW on the Cowlitz River in the vicinity of Morton and Randle, Washington. The project would inundate 12.3 miles of the Cowlitz River and 1.7 miles of the Cispus River, and would consist of: (1) a concrete-gravity dam at River Mile (RM) 88.6, extending 140 feet above the streambed, with a 15-foot-wide, 800-foot-long crest, and containing an ogee spillway overflow section with four radial gates; (2) a power intake structure integral with a non-overflow section of the dam; (3) a reservoir covering 870 acres, with a total volume of 13,150 acre-feet; (4) an indoor powerhouse integrated with the dam and intake; (5) a switchyard located about 500 feet downstream from the powerhouse; (6) a tailrace and modified channel, extending approximately 1 mile downstream from the powerhouse; (7) a 115-kV transmission line, extending approximately 5.2 miles to a new substation at Glenoma; and (8) appurtenant facilities.
