Ririe Reservoir, dam in Upper Snake River Basin, Bonneville County, Idaho, USA
Ririe Reservoir is a large water body in Idaho created by a dam built in 1972. The lake covers about 1,560 acres and holds several fish species including kokanee salmon, rainbow trout, smallmouth bass, and yellow perch at varying depths throughout the year.
The Ririe Dam was constructed in 1972 to control flooding and support agricultural water needs in the region. Water levels fluctuate seasonally, dropping in fall when the lake is drained for irrigation purposes and rising in summer for recreation and fishing activities.
The site has multiple boat ramps, parking areas, and Juniper Park campground with tent and shelter options. Water levels change significantly by season, which affects accessibility to certain spots and fishing conditions, so plan your visit accordingly.
Kokanee salmon fishing peaks in late summer and early fall just before spawning season, when the fish are most active and growing rapidly. Many anglers use specialized techniques like down-riggers to reach fish schools scattered at various depths throughout the water column.
