I'm going fishing on a lake here in TX on Saturday that is filled with cover! It's a state park lake, about 350 acres, built for trophy bass fishin. I want to catch cats or crappie. The question is, how do you find fish when practically the entire lake is filled with standing timber, brush, etc.? Supposedly some real nice cats in there, over 20 lb channels. thanks for the advice for this semi-rookie!
