Chinook landing has plenty of bass around! the eastern part is good, but try behind the wing dam (which is the wooden poles that stick out of the water in a straight line) Spoons are good but also try lures such as spinners and crankbaits.
Plunking can be a good method if you do it in the proper place. Downstream of the wingdam I mentioned is the best spot at Chinook Landing to plunk in my opinion! Use worms!
Good luck!
