Description : Merwin Dam Hatchery, located on the North Fork Lewis River downstream of Merwin Dam near Ariel, Washington, began operating in 1993. It was constructed by PacificCorp to mitigate for losses of resident and anadromous trout resulting from construction and operation of the Merwin Project on the North Fork Lewis River. The goal of the hatchery is to provide winter and summer steelhead, sea-run cutthroat trout, and rainbow trout for harvest by sport anglers.
