Just curious. This weed has popped up in the zone between where the high water mark was and, the new water level. (Down 20" from Aug 1st).
Is this a mature duckweed? FYI, there is zero duckweed in the water.

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.
