Every other month or so, I take a trip to the local lock and dam to try out my luck for some cats. I still have yet to catch anything. There are usually a few people out there that catch some cats up to around 20 pounds from what I've seen. They all claim to have caught much larger fish when using their larger rod setups. Is there anything special that you can do to increase the chances of catching anything? The water is thought to be around 30-40 feet deep in the middle.
