I fished Soo lake in our Monday Night Musky League, The water temps there were low to mid 60's. The Musky were active, We lost a solid 42" fish at the net and saw a lot of other fish. The locals are saying how bad the weeds are out there but I still found a lot of fishable water. There are some big areas that the weeds are matted and unfishable but don't let the talk scare you away from this lake. I'm going very back soon.
