The creek is no where near 30 feet deep. I have about 15to 18 feet of rope on my minnow net and from the top of the wall it easily reaches the bottom. I would be surprised if it is deeper than 12 feet anywhere. I think lures would be useless in the (very dirty ) creek. Fishing the creek with worms, chicken livers ,or minnows should yield catfish. There is a lot of boat traffic on the weekends. Best of luck!
