Columbia River

Looking into planning a trip from ND to Washington possibly next spring to try pull an upper teens pound walleye out of the Columbia River. Just seeing if there has been anyone who has been out there. Seems weird how little info is out there about it. Not looking for anyone secret honey hole, just where to start and what to expect for ramps, navigation, time of year, general location, spawning time for there?

Not much help but I think you’re looking in the right area. Those annoying trash rough invasives get long and heavy there.

It’s funny how they frown upon walleyes there. I’ve heard they are nothing different than carp to them.
