Sam, I don't know if they drew the lake down years back, but yes i remember houses and cottages on the east side getting totally demolished way back when from ice shoves. Since then I know they draw the lake down 2 feet in fall. I only know this only cuz people on the lake say around Oct the lake just drops and they wouldn't be able to get their boats on the lifts. How much they drop the lake, I don't know, but the shallower water near shore has to help the shoves possibly. I don't know that answer but i agree, 40 years ago or so all I remember was talking about who's lake home or cottage had ice damage. I think it still happens a bit but not to the extent years back.
I agree with other posters, I'll throw back a 17+ to keep a limit of 14-15's all day long. I don't like those thick fillets, they start to taste like a white bass. LOL. not really.
