In any kind of flowing stream, whether it be a big river, small river, or a little creek, always remember the concept of riffles, holes, and runs. This system is extremely easy to figure out on small streams because everything is really confined. Just look for the deepest holes. Some times i have good luck in small streams if I can find a big tree with all of its roots hanging down in the water, catfish seem to like that. Fish for the active cats at the head of the holes and in the riffle area. I've caught a lot of cats on cut bait, stink bait( junnies sewer bait), dew worms, and green worms in the small streams. Good luck
