I was hoping for an acre which I am guessing is about the size that it turned out to be, but I am not very good at judging such things. Once it appears in the satellite photos, I'll get an accurate area. It seems a little smaller than our 1.25 acre pond that I know the size of, but I do not trust my estimates. I will stock it based on it being 1 acre. First with forage and RES, and then with SMB. I love these types of projects!. The dam turned out way too steep, so our first project in early Sping is to transplant some reeds in the water, horsetail above that, and a tall perennial sod-forming grass above that.
