I hope they are careful when they go to reduce the weeds. Lake Mahopac in NY state had lots of weeds years ago so the homeowners had a study done. They then put in 3 times the amount of grass carp that the study said they needed. Very shortly thereafter every single weed was gone. They decimated the lagemouth population. The smallies loved it and thrived.it has since recovered some 25 years later but now they want to do it again from what I have heard. Total stupidity in my opinion.
