Refilled feeders and noticed that, though water levels are up a good foot, they never did get high enough to go over emergency spillway. Grass gets pushed down and little fish get trapped trying to escape when that happens, but there was no sign of either.
Water is murky but not muddy. Considering my issues with bushy pondweed, the murk is welcome. Standpipe in back of dam flowing vigorously, but without any hydrogen sulfide smell whatsoever. My best guess is that all the rain has helped push out loads of the anoxic water on bottom already. Anyway, no sign of a fish kill, for which I am glad. Sometimes it's an advantage to be only moderately successful raising fish!
