walla walla river!!!!! At wahlula junctuion.
Therres a state park there but the fishing can be excellent! The usual baits all produce but I've had the best luck with fresh cut bait!
Remember if you get away from the usual spots(bust some brush) your chances improve immensly! Good luck! My biggest is 16#,but lost one that was bigger. Had a night last year where i hooked 6 fish ranging from 5lbs to 10 lbs.Not a bad night fishing!oh yeah those fish might still be there i released them all!
The walla walla river flows into the Columbia and the first few miles are very productive!
Right out on the Columbia there is a grain elavator and those fish will gorge them selves on grain dropped when loading the barges.they get alot bigger than 16lbs too.I've heard rumors of 28 -30 lbs fish. Good luck
