Good luck in that endeavor! My parents' old neighborhood has several ponds ranging in size from 1/5 acre up to 5 acres. Most people in the neighborhood didn't fish so they really had no interest in what went into the ponds and then the rest who did fish were not interested in managing them properly.
Perhaps with a smaller group of home owners you'll have more luck. I believe they ended up posted signs similar to " Fish and Boating for Residents and Their Guests, All Others Will Be Prosecuted for Trespassing" It seemed to work at keeping some non residents from fishing the pond. But most of the management was done by just a couple interested people at their expense for others who didn't want to chip in to enjoy...
