The Carroll county watershed authority released 1000 grass carp in the lake to control the grass. Very effective thus far
With what I saw last year they need more like 10,000 carp. Beech lake in Lexington is just as bad and has been for around 4 years now. I lived on Beech lake and back then there was never any grass.
Problem with grass carp is they feed aggressively when growing but once they get older and big they become very lazy. Fun fish to shoot in heart of summer.
