Mainstem Snake River

Report on fish population by species below American Falls Dam is now available. The IDF&G survey took place between Oregon Trail and Pipeline boat launch points in March. Rainbow Trout are dominant with some brown and cutthroat trout, a few bass, whitefish, and yellow perch. Increased flow for irrigation has slowed fly fishing some in the river above American Falls Reservoir. Flow below American Falls dam is up to 5750 cfs because the irrigation season has begun.  Easy wading here is finished for several months.  All boat launch ramps are open.
