We have a pond about 2.5 acres and are having a hard time sealing it to hold water. There were a lot of trees we had to take out to dig the lake out and was wondering if the water is seeping out where the trees were? Also the dirt is mostly silty loam with very little clay. When we fill it up the water leaks out and only leaves a pretty small area that is sealed. We are thinking of renting a vibratory sheepsfoot and packing it. Will it do a good job of packing this type of soil? Thanks, this is a great site!
