At the Eagle Creek National Fish Hatchery, eggs are collected from winter-run steelhead trout from January to April, from spring chinook salmon in September and October, and from coho salmon in October and November. Salmon and steelhead trout smolts are released from April to June to begin their downstream migration to the Pacific Ocean. The hatchery is open daily except Sundays and holidays from 7:30 a.m. to 4:00 p.m. The best time to visit is during steelhead spawning operations March through June.
