The recent rains washed a lot of amonia into the creek from muck piles and field run off, the result was an overnight explosion of duckweed. Even at 13-9 todays reading the flow was there but also the weed. The amonia level went from .10 Wed. morn. to .62 thurs. morn.
The creek is not a total cover but not far from it either.
