Moose the water is gin clear on my lake. I mean bottled water clear. Especialy this early in the year before the "stuff" that you can name and I cant starts growing. The Hydrilla, Coon tail stops at about the 20 ft deep level.
Again I have never heard of grass pulling a brush pile down so I dont know for sure. I did read in Blakes article that that brush piles made with green leaves on them will sour and catch silt and the silt can pull them down. However he makes no mention of growing grass overtaking them.
On another note get us some pics from your last fishing trip up. I cant wait to see em and read the storys.
