Mine is running out the overflow pipe again. Last year was just at average rainfall for us. I think my leak has slowed with the soilfloc and passing of time. Possibly natural sediments. I will say seeing a full pond is nice.
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
