Bcm, we had our 100 acre lake infested with weeds last year. Tried everything. Eventually it died out, but at one time was so bad it looked like you could walk from one shore to another. Like foam on the surface. If we didn't ski everyday, our path would weed over and we were done.
Any advice for large scale weed control? Was milfoil, duckweed, Alge, and probably a few others.
