Update.. Trying to compare year to year data on water loss. I was losing about .44" per day last summer. In the last 22 days I've been losing water at a .32" per day rate. Very little rain over the last three weeks. Mostly hot and dry. (1.5" rain in last 22 days.) Jeff
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
