My family has a pond that I manage. We have Hybrids and true gills, channel cats, red ears, Large mouth bass, and I have been slowly gettin some of them bronze submarines...aka...small mouth bass put in there in place of the large mouth. Also some yellow perch, grass carp. Its big, and its deep with 3 springs feeding it. 2 ancient fire pits carbon dated from the 1400's were found during its creation. check my pics!
