Irrigon Hatchery Visitors' Guide

Irrigon Hatchery began operation in 1984 as part of the Lower Snake River Compensation Program (LSRCP)—a program to mitigate for spring Chinook and summer steelhead losses caused by the four federal dams constructed on the lower Snake River. This facility serves as an egg incubation and rearing facility for summer steelhead destined for the Grande Ronde and Imnaha river systems and egg incubation for 575,000 Umatilla coho eggs for transfer to Cascade Hatchery. Irrigon Hatchery also rears 1.4 million fall Chinook for the Grande Ronde and Snake Rivers and is used as a rearing site for legal-sized and trophy rainbow trout destined for northeast Oregon waters.
