When you know to target these areas, you will capitalize on the catfish in the pond, because they like to slip back into the structure and wait on unsuspecting prey to come by, so they can just reach out and nab it without having to really work for their meal.

The bigger cats in the pond will feed on other, smaller fish in the pond, even smaller catfish.  So, if you look for the presence of other, smaller fish, minnows, crawdads, insects, etc. You will find catfish nearby.
 
You can use a bobber to fish ponds, particularly if there is a lot of grass or brush on the bottom of the pond.  The bobber keeps the hook suspended off the bottom so you don't get caught up as often, but when you can, try fishing with a weight and no bobber.  Just keep a finger on the line, and when you feel that little tell tale jerk, you know you have a fish on the line, and you can just reel it in.  Ponds often have muddy bottoms, and especially when it is hot, the cats like to burrow down in that mud, because it helps keep them cool, and it provides cover so they can lie in wait for their prey to come along.  If you fish without a bobber, your hook gets right down on the bottom where the catfish live, taking their dinner to them!  Anyone can successfully fish a pond, if you just make these small adaptations to your technique and use a little care!
