wondering about stocking chanel catfish

[fishfinder401]

i was looking to get a little variety in the pond in my neighborhood and channel cats seem to be a good choice, can anyone tell me any specific info on reasons to stock them, anything would help, i will need to convince our association
the pond is around 3-4 acres, avg depth around 5-6 ft hard bottom in center and muddy around edges
already has healthy pop of largemouth and large bluegills
