TEACH Questions & Answers

What is the highest elevation of the water of Lake St. Clair ever recorded?
from Cameron in Plymouth, MI, Age 12

The levels of each of the Great Lakes depends on the balance between the quantity of water entering the lake and the quantity of the water leaving the lake. So if these quantities remain precisely the same, then the general water level for the entire lake stays constant. If more water enters the lake than leaves it, the volume of water in the lake increases. This causes the lake level to rise. If less water enters lake than leaves it, then the level of water in the lake decreases.

The Great Lakes Environmental Research Laboratory reports a maximum water level of 576.69 feet (or 175.77 meters) for Lake St. Clair. The average range from month to month spans from 0.4 feet (or 0.12 meters) all the way to 3.3 feet (or 1.01 meters) in a single month.
