I am the person in north central Texas with the leaky dam put in by Mr Hale. The Fannin NCRS gave me a 80 page booklet (from NCRS) that showed/warned about all the things that was done wrong and options.
One, and the cheapest is to lower the water to the original ground level, if possible, and rototill in rock salt at 2/3 pound per 1 square foot? (get the booklet from NCRS to get it right). I asked all the question about salt and fish, and he brought out books showing how it adds to the protective slime, et.al.
Results, significant reduction in leakage, I only loose about 200 gallons a day instead of about 2000 per day. Boy do I have a nice field of Cattails!
