Two of my pond builds so far have been limited in depth by the water table. Normally you can't dig more than 4' here in Jacksonville without hitting water. After all of these storms and tropical storm Fay the I can't dig more than 2' without hitting water.
What are the secrets to digging deep and not having your pond fill up with ground water?
Another huge problem is this...If i dig too deep, and put a sump pump in the lowest part of the hole to suck the water out, the vertical walls start to cave in from washout.
Any pool builders here?
