Just found this thread. Very nice looking pond! I've been going through some of the same situations with building a pond. Mine is on a smaller scale, and no spring to fill it. I'm waiting on rain, and it's pretty dry in NE Missouri. Plus I didn't come in "under" budget! Ha. Looks nice. I wish I could have done it when my kids were younger, but it wasn't in the budget back then. I'm trying to lure the grand kids out now. Jeff
12 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs) I think that's about all I should put in my little pond. Otter attack in 2023.
