didnt know the columbia had bass in it????????
oh man its a world class bass fishing river. many many tournys there every year. mostly up towards hood river and the dalles.
look for current seems very close to deep water. or humps. tubes shoul be working awesome try outlaw gitter tubes which can be found at sportsman warehouse. yozuri lipless cranks and lv500 from lucky craft are awesome. a drop shot should always produce, try gobys from bass8baits. man if you ever want to get out send me a pm. i promise we will find fish. hope you like smallmouth left and right lol.
