Had a pond dug about 2 years ago. 1/3 acre. Looked like pretty good clay all around. Very little natural drainage to it though. All home and barn downspouts go into it, but wasn't enough. Dug a well last fall which seemed to be filling it. However, it got to within about a foot and a half of the rip rap and overflow pipe, and doesn't seem to be making any more progress. The well is producing 12 GPM. I calculate it should have finished filling in about 10 days, but it has been working at it for a couple of months. What solutions are out there for sealing without having to drain and add clay

OK. did more research. I guess Bentonite is my only realistic option. however, can't realistically empty nearly 1M gallons of water. I've seen mixed reviews on broadcasting it over the water surface...any ideas?
