great lakes watersheds

The great lakes basin consists of the great lakes and the surrounding lands of the states of illinois, indiana, michigan, minnesota, new york, ohio, pennsylvania, and wisconsin in the united states, and the province of ontario in canada, whose direct surface runoff and watersheds form a large drainage basin that feeds into the lakes. it is generally considered to also include a small area. Take the lake ontario watershed for example. all of the surrounding small watersheds eventually flow into lake ontario, making up one big “lake ontario watershed.” this watershed combines with lake huron’s watershed, lake superior’s watershed, and all of the other great lakes until you have one massive “great lakes watershed.”. The great lakes are a vast shared resource. they contain roughly 18% of the world supply of fresh surface water, and 84% of north america’s supply. they are home to millions of people, and are fundamental to the well-being of one third of the population of canada and one tenth of the population of the united states..
