Sulvenia Molesta doubles in area in 5 to 7 days. The stuff is so thick you can't run a boat through it.... not even at full power. The fine, hairlike roots get sucked up into the motor and clogs everything. Lake Wilson looked like a golf course.
For those of you where not here when the lake was closed.... It took almost a year and over one million dollars to clean up the lake.
They would crag the stuff over to the side and scoop it out. The shoreline was sprayed with Roundup.
