Thanks for the comments.
Eddie -the pond stayed at 3 acres, but now a much deeper 3 acres(6' to 8' in shallows 10'+ in deep end with trenches)and cleaner around edges.
-the dam was leaking due to what appeared to be poor soil. Also there were trees on back side of dam so possible roots. During renovation the dam was taken down and built back with good soil(clay) and made very wide and topped with topsoil.
All the dirt was used to "landscape" around the pond. Before renovation very flat and wooded around edges. After renovation have hills and berms, allot of "character" added to place. Starting to grow grass on these berms and can really tell where edges of pond will be. It looks great and did not have to truck dirt away$$$.
Ewest - in the rains so far the trenches are filled and shallow end has water in bottom. Hopefully by next rain will completely cover bottom
