The thing is they wouldn't exhaust their supply. There would be a point where there was not enough food to maintain a population at a certain level, and that's why you would have those trends that go up and down. They go down because they've run out of food. Then when the numbers lower and there's more food available, they go up again. As our modelling indicates, there's plenty of food in places like the western basin of Lake Erie, Green Bay, and other areas of the Great Lakes for them to achieve those populations.
