Erie is one of the best places for big smallies. Huge shallow, productive lake, with lots of forage. It was in trouble for years, being anoxic over large areas due to lots of algae growth fostered by phosphates that used to be used in soaps/detergents that were flushed down countless drains. That problem was taken care of, and Erie has been doing really well for the last 10-15 years.
Now, they face a potential problem with the introduction of a goby species that preys on smallmouth eggs. Hope the goby doesn't wreak havoc on the smallies in the long run.
