Well, it's a hot summer once again. I'm still losing the same amount of water per day (roughly 7,000 gallons). Aside from using polymer on the inside of the dam, repairing the 1 acre pond either by hauling in clay, bentonite or other material is out of the question.
My guy came up with a cheaper solution. We created a 1/8 acre containment pond below the toe of the main dam with the end goal of pumping the water back into the big pond. It's fed by the leak and what appears to be a spring. Despite the lack of rain it's been filling every day since we completed the job on 7/3. It should hold 90-120 thousand gallons. It could double in size if we blow out some trees and build up the dam another 4-6 feet.
Now I need to figure out an ideal pumping solution, preferably electric on a timer.
