I had 70 degrees on the surface last week. We had several days in a row that were above 80 degrees ambient and very sunny. That was a week after we had a record snow of 7" and the water was pretty muddy for a few days with the sun on it.
It's cooled back off here for the last week or so - I doubt my water temp is more than about 50 today but it poured rain for the last 2 days so, I haven't been out there.
