I'm going to be. (At peace with it.) .3" per day will work for me. I'm certainly not going to drain it, and rework clay into the base of the pond etc.. (Enough invested already.) If it slows down a bit more as time passes, great, but if it's .3" a day forever, I'll be fine with that..
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.
