State officials have announced changes to the spring chinook fishing regulations effective Thursday on the Kalama and Lewis rivers.
Chinook must be released in the Lewis River from the mouth upstream to the power lines downstream of Merwin Dam.
The forecast is for a return of 1,100 spring chinook to the Lewis River in 2016.
The hatchery system needs about 1,350 chinook.
The river will remain open for steelhead fishing, except from Johnson Creek upstream to Merwin Dam is closed to all fishing in May.
