Mdod, I'm in a similar situation as you. I have a pond that is about an acre and a 1/2. I am toying with the idea of adding another 1/4acre or so to the pond. I'd like to dig out a deeper section (most of the pond is between 4 and 5ft) and then simply put an 8" extension on the drain pipe near the dam to raise the water level in the spring when the snow melt stream flows into the pond.
But before I do that, I'd like to clear another 1/4acre out and give it some depth, just a few dozer blades in width but maybe 8 to 10ft deep. I have hard clay all over the place. So I am hoping by bringing the water level up, I can flood the newly dug area and then bring the water level back down to normal levels so if the area leaks, it won't effect the rest of the pond all that much.
