Notice the water level is down 4'. It was worse until recent rains. We have been in a pretty serious draught up here until last weekend. The leak is probably half the water loss, evaporation accounts for the rest.
9 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these. I think that's about all I should put in my little pond. Otter attack in 2023
