Hello from SA,TX.
I built my 1st pond (small about 1 acre) in '72. Built it twice as the 1st operator didn't know what he was doing and had to have a 2nd come in and knock the dam down and put in a good core. Sold the place a few years after that and been without ever since. Plan to change that. So much knowledge here and more interesting that reading county ag books.
