How is the Columbia River in May????

Should be good, The water temps should be in the fiftys.  Will be prespawn, ( Jerks baits, rattle traps, spinner bait ect. ) so look for that pattern.  Depends what area of the columbia your fishing but it has some nice flats next to deep water.  It's big water with alot of current at times. Lots of grass also, I have keyed in on grass flats and killed them before. Biggest thing is look for the current breaks.  Enjoy
