Maybe it was 57, 59 and 60 ?
The temperatures should be correct. The thermometer came freshly calibrated from UNH just a few months ago. I don't know why NOAA's water temperature data is 9 degrees lower. Perhaps they aren't out in the water doing measurements, but it is strange that they would report if they weren't confident of the data.

Other lake monitors that sampled this week are reporting similar temperatures as what I saw.

The northeast part of the lake gets most of its water from the land (30:1 ration of land to water), is more shallow and is darker, so gets more solar heating. It normally both freezes and thaws well before the broads.

Here is a graph of the temperatures by depth. Greens Basin is different from the others. Excuse the Meter and Celsius format.

Making an August update to show the difference between June and August temperatures and the thermocline. Greens Basin is still the odd one, and in July it was oxygen depletion was measured at the bottom there.
