Lucky Peak Overview
Construction of Lucky Peak Dam and Lake began in November 1949, and the dam became operational in March 1955. The facilities include Lucky Peak Dam, Lucky Peak Lake, Federally-owned lands managed by the Corps, and recreational areas. The dam and lake benefits include flood control, fish and wildlife, irrigation and recreation. The dam and lake were completed in 1961.
The dam is a rolled earth-fill dam, 340 feet high and 1,700 feet long at the crest. The spillway, located on the left abutment, has a 600-foot-long, free-overflow concrete ogee crest. The outlet works, located in the left abutment, consist of a 23-foot diameter tunnel with six 5-foot by 3-inch by 10-foot slide gates. The emergency gates are two 10-foot by 23-foot Broome-type gates, and are located in the intake tower.
Behind Lucky Peak Dam is a storage reservoir, Lucky Peak Lake. The lake, when full (elevation 3055), is 12 miles long. It has 45 miles of shoreline and 3,019 acres of surface area. The lake provides a total storage capacity of 306,000 acre-feet at elevation 3060.
There are 4,288 acres of public lands surrounding Lucky Peak Lake. These lands include lands that are Federally-owned and managed by the Corps, as well as easement lands to which the Corps has specific rights or easements (i.e., flowage or access). There are 4,079 acres of Corps-managed lands that are utilized for public recreation purposes, wildlife habitat, and operation purposes. There are ten major and ten minor recreation sites along the lake. The State of Idaho operates Lucky Peak State Park at three locations around the lake. Lucky Peak State Park is the most visited state park in Idaho. Other recreation areas are operated by the Corps. The lake lies within the Idaho Department of Fish and Game’s Boise River Wildlife Management Area, the major game range in the state. The State of Idaho has developed wildlife habitat especially for mule deer on Lucky Peak lands.
Under a memorandum dated May 24, 1984, a powerhouse was constructed, and is currently owned, by the Boise Board of Control (a consortium of local irrigation districts). Seattle City Light, the purchaser of the power, operates the powerhouse. The powerhouse construction project included a visitor center, reconstruction of the existing outlet and construction of a second outlet plus the mitigation and enhancement of recreation and operation facilities.
