Ririe Reservoir, located in Bonneville County, Idaho, was created in 1975 by the Bureau of Reclamation as a flood control project. Situated on Willow Creek just five miles east of Idaho Falls, this 1,414.5-acre reservoir offers diverse fishing opportunities in a stable aquatic environment. Unlike many Idaho reservoirs that experience significant irrigation drawdowns, Ririe maintains stable summer pool levels, creating consistent fishing conditions throughout the season. The reservoir serves multiple purposes including irrigation, flood control, and recreation, making it one of the most popular flatwater angling destinations in the Upper Snake Region.
