1> If you want to catch more (and who doesn't) use a clear 2 or 4 lb line. Fluorocarbon isn't a bad choice.
2> If I can't catch them on a tiny inline spinner I'll tie on a #10 egg hook, add a single tiny splitshot, and a piece of whole kernel corn from a can. I also keep power bait and salmon eggs on hand.
3> Personally I've had much better luck up near the dam. I guess everyone's got their favorite spots though.
4> if it has sat on the bottom for more than a minute or two reset or rebait.
5> Be ready to egress in a hurry if they open the turbines. The water rises faster than you would think.
6> Watch your line closely when using natural baits. They may swim towards you while swallowing the hook.
7> Don't go the day after JWalker77. All of the fish will have sore lips.
