Columbia river: water levels are high with a occasional catch and release sturgeon.
Lewis River: Winter Green water levels are not perfect but very fishable conditions. There are a few Coho left in this system with a occasional winter chinook.
Kalama River: water levels are high with brown water.
Cowlitz River: high but very fishable. I would focus up at the Barrier Dam area for Late Coho and early winter steelies.
Humptulips River: it seems that every river in the NW is either high or not fishable… the hump is fishable but high. Focus up at the hatchery for late Coho and Steelhead.
Wynoochee River: very High.
Satsop River: High water which this time of the year means winter steelhead… that is not the case as fishing is very slow with a occasional late Coho.
Chehalis River: this river is definitely brown but if you can find clean water coming in you can catch late Coho.
Note: as always check your fishing regulations for the laws.
