There may be restrictions during boating hours. I don’t really know. I only fish PL for redears till till the end of April and not all that often. I prefer peace and quiet and trees on the shorelines not big party houses.
Nice fish! If I had some electronics, I would be trolling along the edge of the ski zone looking for schools too. I would think that you could fish there as long as it's not during the fast boat hours. It doesn't say no fishing on the sign. At least it didn't last time I looked a few years ago.
