I had five otters a few years ago. I talked them into leaving. Knock on wood, I haven’t seen any since. I restocked YP. So, the otters will probably be back. My pond is only a few miles from Mark Twain lake. It has an otter problem. I’m sure that’s where my otters came from. Nothing I can do about that, but just wait for them to come back. I was very fortunate in that the ones that did show up were relatively stupid. They swam around me even in the middle of the day..
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.
