Pond digging

We are also busy with having our pond re-dug out and reshaped. we ran into some big problems with the pond last summer and its finally getting fixed. When we bought this house 3 years ago we were told this 1 acre pond was really deep. It was going into winter when we bought the house so we never got to check it out. The first summer we discovered, while it is an acre big, it was very shallow! You couldn't swim in it and because it was so shallow it had no air or water circulation and it basically was a giant swamp hole and with the heat of the summer, it turned into a stagnant water hole. SO last summer we hired someone to dig it out and make it deeper. We knew that there was risks with this as when you are digging into standing water you have no idea what is underneath there. There is always the odds we could have run into a rock bed or the clay bed would not have been deep enough and we would have dug into sand. Which if that happens the pond would have completely drained out thru the sand then we would have had to dig all of the sand out and put in a new clay bottom. Well that didn't happen but whoever originally dug this pond put It over the top of what used to be farm ground. Tiled farm ground. when they started digging the pond deeper last fall, they hit several tiles that no one knew where there. This in turned caused the whole pond to drain in a mater of days. This also uncovered a fence that the people who had put the pond in had left. So the fence was smack dab in the middle of the pond too and that had to be removed as well. So winter struck and we had a mess out there. My daughter said it looke dlike armageddon out in the front yard. So we have had a very ugly yard to look at all winter. We couldnt dig anymore because the ground was frozen and the snow was deep and had filled in the hole. So we waited till spring. And we have had such a cold wet spring that they couldnt get back into the pond until just 2 weeks ago because the equipment kept getting stuck in the muck. Now we are finally only 2 days away from being done. They have made the pond bigger and alot deeper and they have smoothed out the edges of the pond and slopped it nicely into our yard. Its not done yet but soon we will be able to plant grass around the whole pond again and then wait for the rains to fill it up again.
