I wonder if the temperature at the bottom of a surface frozen lake is 4 degrees. with significantly higher temperatures only at the very bottom.
But below 40. 1 degrees Celsius, water behaves differently than most substances and becomes less dense the cooler it is. Once the water temperature of an entire lake is below 40. 1 degrees Celsius, the coolest water is found on the surface of the lake. And this is where ice forms.
Sep 11, 2013 Researchers have found signs of life in mud pulled from the bottom of an icecovered lake in Antarctica.
Fresh water is most dense at 4 degrees C. That means that water at that temperature will sink to the bottom, and the water at the bottom will not get colder than 4 degrees unless the entire lake freezes from top to bottom (unlikely in any lake deeper than a few feet).
The daily lake temperatures for Lake Erie off Buffalo and for Lake Ontario off Rochester are included in the Nearshore Marine Forecast.
However, deep lakes tend to have bottom temperatures closely approximating average underground temperatures, which depend on latitude. The water at the bottom of Table Rock Lake in southern Missouri, for example, is around 55 degrees yearround.
