I’m not an expert, but I’ll throw in my $.02 worth. My pond isn’t too far south of yours, in NE Missouri and I share the same drought. Mine was built almost four years ago, but hasn’t been completely full for over a year. It’s down 3’ from full right now.
I overstocked fish three years ago, because I was planning on running a feeder, and an aerator. I’ve since scrapped the aerator plan, due to cost issues, and am not feeding heavily as I’ve got a very large population of GSH.
My fish are doing very well. Fat and happy. I haven’t lost but a handful of fish (that I know about, maybe they all sink).
My impression is, it takes a while (several years) to get to a point where there’s too many fish for your pond. I’m sure it’s all about water volume and total biomass, but my guess is you’ve got several years before you need to be concerned. BUT, lm NOT an expert.


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.
