Yes, we did, but it was coming in faster than the pump could keep up. We had hit 8' deep at the point, and it was very sloppy. We figured that 8' is deep enough. We have dug three ponds on my property and have yet to hit 10' due to water flooding in. The good part is that my ponds never drop more than a foot no matter how dry it is. We are in the snow/rain/sleet/gropple belt of NE OH, so there is very little sun, (like 60 days of it a year) and lots of precipitation thanks to Lake Erie, so evaporation is not much of an issue here.
