The falls is my second home in the spring, summer, and fall. I have fished there for quite a few years. I always try to target catfish and I have found the best place is right under the observatory. There is a fairly good sized hole there to fish. But the best time to fish is when the water is 16ft or lower. I use either skipjack or carp. And a heavy weight is needed t keep your bait on the bottom. If your in the Louisville area I can turn you toward a few other spots that have produced goo catfish for me.
