i am no expert either.... but from what i can figure is this most farm ponds are fed by underwater aquifers or springs and the underground temperature of the water is a constant of around 50 but with that flowing in underneath that forms a thermocline much like a lake when the water gets cool the deeper u go....... and in most cases in farm ponds there isnt alot of stuff for fish to feed on such as the buffet at a lake....... but i have always had good success in farm ponds fishing shady areas under trees and stuff.... or out deep.... and plus there isnt alot of places for fish to hide........ i hope this helps......
