Got up to the pond today. I have another 12" of water up from last week. We had a 2.5" rain that came down very fast. Most of my drainage comes from 10 acres of alfalfa. Not sure what the renter has sprayed on it. He used dry fertilizer earlier this spring. Anyway, had a lot of runoff.
95 degrees all week, and no water actually leaving the pond, as I'm still 2' from the drain pipe.
Have some pretty colorful algae growing. I decided not to swim after reading this thread.

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.
