Use our Fish Stocking Schedule to learn where, what type, when and approximately how many fish Idaho Power will be releasing.
Types of Fish
Idaho Power stocks rainbow trout each spring and fall as a way to improve sport fishing opportunities. This also helps us to meet requirements associated with our federal licenses to operate our hydropower projects on the middle Snake River,
Rainbow trout are stocked in American Falls Reservoir, several locations in the Hagerman Valley and C.J. Strike Reservoir. View the Rainbow Trout Stocking Location and Fishing Access Map. In addition to stocking rainbow trout, we also stock channel catfish annually in Milner Reservoir.
Steelhead and Spring Chinook Salmon
We also stock adult steelhead and spring Chinook salmon that are surplus to hatchery needs.
Hatchery steelhead and spring Chinook salmon are trapped at Hells Canyon Dam as part of the Oxbow and Rapid River hatchery programs.
Fish Stocking Locations
After enough fish have been trapped to support the hatchery program and other management needs, some surplus fish are made available for stocking into the Boise River, Powder River and Hells Canyon Reservoir. This stocking program is managed cooperatively by the Idaho Department of Fish and Game and the Oregon Department of Fish and Wildlife.
All fish planted by our stocking programs are managed by the Idaho Department of Fish and Game and subject to licensing rules and regulations for those specific waters. For information about fishing seasons and licensing requirements, visit Idaho Fish and Game.
To evaluate some of the rainbow trout stocking programs, many of the rainbow trout are fitted with one or two metal jaw tags. Information obtained from catching these tagged fish help our researchers determine success of the stocking programs. Learn more about jaw-tagged rainbow trout.
