Went down to the pond this morning before heading to work. The leak by the pipe is back down to a very small trickle. Have to look closely to see the movement of water.
The water is still up about half way around the pipe on the inlet side.
That tells me that the leak is near the midpoint of the pipe.. I'm as green about all this stuff as can be though.

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.
