So glad to hear that there are still some great fish in your pond, Tracy! I guess this reduction in biomass sets the stage for possibly faster & safer growth, almost like starting again. I've found the same pleasure in watching birds as you, except for those Z@#!&% cormorants.
By the way, how is the bushy pondweed doing now? Had mine treated with herbicide, about 95 percent of surface stuff vanished and has not come back. Still there on bottom, though, so it will try to return next spring. Hope grass carp will help keep in check next year.
