Thanks. The link you provided to other threads was particularly helpful - I had searched the forums, but certainly had not found all of those posts.
Various sagitarria, pickerelweed and blue flag irises are definites, and with the existing sedges, bulrushes and smartweed in shallow-slope areas, I feel like emergents are covered. Any recommendations on native submergents that might be compatible with grass carp? Or any alternatives to grass carp or repeated spraying that anyone can recommend for dealing with the Eleocharis baldwinii?
