What causes a lake to freeze clear?
Lakes freeze from the surface downward. If a lake freezes slowly, the impurities and gases are pushed into the water below, resulting in clear ice.

Weather. It is not uncommon for temperatures in the summer to go into the triple digits or below freezing in the winter. Occasional summer thunderstorms occur but are not common. Snow can fall to lake level but accumulation is rare.
Why is there water on top of frozen lake?
Right when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake’s surface. Below 4° Celsius, water becomes less dense as it gets colder, causing water about to freeze to float to the top. Public Domain Image, source: Christopher S. Baird.
Where is the warmest water in a frozen lake?
bottom
Eventually, the surface of the lake cools to 4 degrees Celsius (39.2 degrees Fahrenheit), the temperature at which water is most dense. This causes the water at the surface to settle to the bottom, pushing the now relatively warmer water at the bottom back to the surface.
How do fish get oxygen in a frozen lake?
Different fish species do this either by absorbing oxygen into their skin, into the blood vessels in the walls of their swim bladders, stomach and gut, and some even inhale the air bubbles that form underneath the ice through their mouth.
Do fish survive in frozen lakes?
As a lake freezes, the ice floats on the surface, insulating the water below and keeping most lakes—and the fish within them—from freezing solid. You would still, however, be very cold. Lake fish have to lower their metabolism and enter a state called torpor to reduce their energy demands enough to survive the winter.
Why is Clear Lake Manitoba so clear?
It is oligotrophic, meaning it has low amounts of nutrients in the lake, giving it a clear look and making it a suitable source of clean, fresh drinking water.
Why is clear ice stronger?
Because it’s only water, it’s denser so it melts more slowly and lasts longer. (Air and impurities make it melt away more quickly.)
Where is the most oxygen in a frozen lake?
Throughout the winter then, oxygen levels slowly decline. However, colder water can hold more dissolved gas than warmer water can, so water below freezing holds the most oxygen.
Why does bottom of lake not freeze?
The bottom of a lake do not freeze in severe winter. The reason is that ice is a poor conductor of heat hence once the surface is frozen no further heat is liberated or absorbed by water beneath ice. Therefore water below ice never freezes.

Will boiling water make clear ice?
“Boiling water does not make clear ice. It may make ice a little bit clearer than without, but it makes no significant difference compared to using directional freezing.” There are two methods of directional freezing to try at home—one more involved than the other, but both equally as effective.
How long can you survive in a frozen lake?
In water that is around the freezing point, a person is likely to survive only 15 to 45 minutes with flotation and possibly up to an hour or so with flotation and protective gear before the brain and heart stop (Table 1). The surface temperature of Lake Superior in early to mid-summer is about 40 to 50 F.
Could a fish survive in milk?
Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules. So, though skim milk is nine-tenths water, it still would be entirely insufficient to support a fish for long.

“This can result in a wet layer on the surface of the black ice. Under those conditions, it’s nearly impossible to walk safely over the ice unless you have traction cleats on or know how to ‘ice walk’ (i.e., walk upright with your head back and take short, flat-footed steps).”
Is ice thicker in the middle of a lake?
Re: Is lake ice thicker in the middle or close to shore? Ice on the edge is limited to the depth of the water at the edge. So it is always thicker towards the middle.
