Fished Cave Run on Friday and the Hydrilla which is usually matted up to the surface by now was nowhere to be found. there were of course a few little patches here and there but for example Zilpo (The Flats) had almost no living Hydrilla whatso ever...I dunno whats happened but it looked like it had been sprayed but I dunno, it was very dissapointing as I was planning on working on my grass fishing but I am very concerned about where the weeds are?...Anyone know?
