Bobby unfortunately we haven't had big hydrilla beds on Roberts in a very long time. Very late 90's, since it was all over the place. Some hydrilla would try to grow and just wouldn't last and wouldn't spread. Sucks!
Now we have had plenty of millfoil off an on since then, but as stated the high water keeps killing it off. I have only seen a tiny bit of grass in two places this year, and it is gone again.
