How are the 5 Great Lakes connected to each other?

The water levels within each Great Lake are determined by how much water flows in and out of the lake. These are influenced by long-term natural trends in precipitation and evaporation.
How do the Great Lakes affect the economy?
Changing Great Lakes water levels can impact the economy in a number of ways: Low lake levels impact commercial shipping, recreational boating, hydropower facilities and drinking water filtration plants. Low water levels mean less cargo per freighter to keep from hitting ground which can result in increased costs of goods.
What makes a lake a healthy lake?
Naturally fluctuating water levels are a sign of a healthy lake. Wetlands benefit from periodic high and low water levels, which create conditions for healthier and more diverse plant habitats, and improve water quality so wildlife can thrive.
