Need to figure out how the gambusia got in the pond. Is there a connection with any other body of water during flooding. Was there water already in the pond area before construction? Was it bucket stocked by people? This is important if you want to be able to control what species are in the pond. If you have gambusia, you may have more species in the pond.
