I'm always amazed at how close you can get to the Great Lakes and have water flow away from them.

Yeh, it seems way too small. When you see how fast the Niagara River flows and also the St Laurence. I just don’t get how there is enough rain to supply the outflow.

There is a gigantic bedrock bowl beneath the great lakes that traps anything that falls on it. There isn't really anywhere for the water to go other than towards Niagara falls. Other basins probably have more groundwater absorption by comparison
