Zebra mussels have taken over the whole lake. Main cause of “crystal clear” water which is not a good thing.
Went diving in Lake Ontario, Canadian-side, several years ago. Rolled off the boat and the water viz was terrible. I’m thinking, “Man, this is going to su-” when all the sudden the viz opened up to 80+ ft. Yep! Zebra mussels. They carpeted everything. Once yo dropped below about 30ft their ability to filter the water took over.
