A lake won't start to freeze until the water from the surface to the bottom reaches 40F. It can be noted by simple observation that this happens first around the shoreline. Once the whole lake reaches 40F, the surface will continue to get colder. When the surface of the water drops to 32F, it starts freezing.
A lake freezes at 32 degrees Fahrenheit (0 degrees Celsius). The temperature needs to be consistently below freezing for the lake to freeze completely.
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
The Great Salt Lake would freeze at a higher temperature than Lake Tahoe because it has a higher salinity level. The salt in the water lowers the freezing point, making it more resistant to freezing than fresh water.

No, Lake Tahoe has never completely frozen over. It is to large a body of water (about 40 trillion gallons) for the core temperature to get low enough to freeze. On occasion, Emerald Bay will freeze over which is attached by a narrow, shallow opening.
The time it takes for a lake to freeze completely depends on various factors such as the size of the lake, the temperature, and weather conditions. Generally, it can take several days to weeks for a lake to freeze entirely during cold winter temperatures.

Yes, Lake McDonald in Glacier National Park can freeze over during the winter months, typically from late December to early March, depending on weather conditions. However, the extent and duration of the freeze can vary each year based on temperature fluctuations and snowfall. The lake's unique features, such as its depth and inflow of warmer water from springs, may also affect freezing patterns.
