About this place

Lucky Peak Dam was authorized in 1946 to provide flood risk management, irrigation storage, recreation, and environmental stewardship. The dam holds back reservoir of approximately 265,000 acre-feet of water extending fifteen miles upstream (about a quarter of the 1M acre feet stored by the three-dam system on the Boise River comprised of Lucky Peak, Arrowrock, and Anderson Ranch). In 1984, the irrigator-owned Lucky Peak Power Plant Project was authorized, beginning construction of a 101MW hydropower facility that completed in 1988. Today, Lucky Peak Lake hosts about 900,00 recreational visits annually, provides invaluable wintering range for mule deer and elk, and reduces the risk of flood in the Treasure Valley. This tour for family groups and individuals will provide an overview of the construction of Lucky Peak Dam, current operations of the dam, relationships with many partners including the Lucky Peak Power Plant Project (non-Corps), and big picture water management considerations of the Upper Boise Basin. For larger tour groups, please make special arrangements by reaching out to the Lucky Peak Lake Office at (208) 343-0671 or emailing luckypeaklake@usace.army.mil .
