Hagerman National Fish Hatchery

The Hagerman National Fish Hatchery (NFH) is located along the Snake River, about 30 miles west of Twin Falls, Idaho. Under the Lower Snake River Fish and Wildlife Compensation Plan (LSRCP), over 1.2 million steelhead are produced annually to mitigate for fish and wildlife losses caused by the construction of four dams on the lower Snake River (Lower Granite, Little Goose, Lower Monumental, Ice Harbor). The hatchery also produces 130,000 Rainbow trout to mitigate for Dworshak Dam in northern Idaho. The hatchery was located in the Thousand Springs area to take advantage of the spring-fed water with a flow rate of approximately 30,000 gallons per minute.
