I've lurked around here for the past year or so. Just purchased a parcel of land that is attached to a shared 16 acre pond that iat its deepest is 18 ft. I had an expert come look at the pond after our purchased and they recommended we get the phragmites down around the pond and add some tree or cover for the fish. Osprey and eagles frequent the pond. They also recommended aeration but admitted it would take a large system based on the pond and the other owners would likely need to be on board. Algae isn't a problem but man the weeds are a bear in the shallows. So far we've caught bass, white crappie, perch, bluegill, catfish, carp and even a large shad. Id love to add trout but not sure if its feasible based on location (SE MI). Just hear to learn.
