I've got to believe that concrete is okay for submersion. Otherwise every government agency and their brother would screaming about erosion and bridge projects, wouldn't they?
snrub: your post about FA struck a chord with me as I have a case of bloom happening now. It seems like it took off with our wet spring last year, and continued under the ice. From what I understand, my first step is to cut off sources of nutrients. A tile line that drains a couple of acres of field and a bunch of bullheads stirring up the bottom are my primary suspects. My water level has also been down since last July so I haven't had much flow of fresh water. Does that pass the sniff test with you? Do you have any other thoughts?
All others please feel free to chime in as well!
