When I bought the property the pond had hybrid bream and bass (not a good combination) plus there was gar. We drained the pond dug out areas along the bank that were less than 3' deep and are waiting on rain to fill it back up. The previous owner had fertilized the pond occasionally and nevef had a problem getting a bloom. I will take it one step at a time and study up on fertilizing to be sure that I get it right when the time comes. You have my location right, I am near Hammond, La.
