Sounds like my little city lake I fish fairly often. I catch all my fish in that pond in 6'' to 3' of water not 5 feet from the bank of the chunk rock dam. The fish are up there feeding on craws and small gills. Most of the fish are 12" to 16" but I did catch one that went 21".
I always make long cast parallel to the bank, best baits have been small jigs and senkos.
