Update. Two more days without rain. Measured on the 15th, it had dropped 5/8", so I'm still doing ok. Just not getting any rain,, as usual.
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.
