It can and it has. In fact, the Chesapeake Bay has been documented as freezing over in winter months a good seven times since 1780 says Chesapeake Bay Magazine. The last time the surface of the Bay froze over was in the brutal winter of 1976-77, when roughly 85 percent of the Bay and its rivers and streams formed ice.

Why is the Chesapeake Bay so dirty?
There are three major contributors to the poor health of our streams, rivers, and the Chesapeake Bay—nitrogen, phosphorus, and sediment. High levels of nitrogen and phosphorus fuel unnaturally high levels of algae growth in the water, blocking sunlight from reaching underwater grasses that serve as food and habitat.
At what temperature does the Chesapeake Bay freeze?
32 degrees
Those sustained cold air temperatures are causing water temperatures to tumble, too. While the freezing point of fresh water is 32 degrees, the point at which water in the Chesapeake Bay will freeze can vary due to salinity levels. The saltier the water, the lower the temperature at which it will freeze.
How many times has the Chesapeake Bay frozen over?

Is the Chesapeake Bay freshwater or salt water?
The Chesapeake Bay is an estuary—a partially enclosed body of water where fresh water from rivers and streams mixes with salt water from the ocean.
