Question

i tried looking in the internet but couldn't find it. please help me.

Answer 1

I am not certain what you want. When it is 4deg C, water is the most dense. So when air temp gets cold, and the surface water cools to 4F, is becomes dense and sinks to the bottom of the lake, and basically, the lake turns over. This contines as the water on the surface sinks, warmer water goes up, and it repeates. The lake circulates upside down, basically. This causes the fish a lot of problems with finding the best layer for oxygen replenishment.

Answer 2

I don't understand your question.

Are you asking about seasonal variations in Canadian lakes?

At 4 degrees Fahrenheit the lakes would be frozen. Of course they wouldn't be frozen at 4 degrees Celsius.

Perhaps this website will help you answer this question.
