OH Gosh -My bottom is leaking
Yesterday I returned a call from a gentleman that was concerned that his pond bottom had not sealed. The man indicated that he had just built a new 1/4 acre pond to water his cattle. He had dug too deep and had hit a shale vein in the bottom of a ravine that he had dammed and the pond would not hold water. NOW WHAT. He had added 3,500 pounds of bentonite clay and that did not work. He checked on a pond liner but that cost thousands of dollars. HELP! Luckily he stumbled on an advertisement of mine in the Oklahoma Living Magazine, a magazine published by the Oklahoma Rural Electric Coop, and called.
We had a brief chat and I suggested 3 options: 1) bring the dozer back in and push a bunch of clay in that was on the sides of the pond and pack it effectively sealing the vein of shale. 2) feed his cattle in the bottom and let them poop and stomp the bottom which is effective in packing the bottom. 3) drain and dry the bottom then spread more bentonite clay, till or lightly disc, pack it with a roller while you wet the clay. The third option will incorporate the clay into the shale, the packing seals the bottom and the water allows the clay to swell effectively sealing the deal. I expect he will use a combination of 1 and 3. He thanked me and hung up a happy man.
Gosh, I guess I should have asked him if I could trap his new pond for crawdads in about a year since he was not going to stock it with fish.
