I fish a local man made lake here in California for channel cats. I fish from a kayak. The lake is fairly flat, about thirteen feet at most, a few islands, a lot of overgrown cattails. My question is, how do you fish for larger cats when there really isn't any deep water? I have caught a couple of okay channel cats, one 19 inches, the other 22 inches. I know there are larger ones in this lake. Any tips would be great!
