Did you know that the some of the water from Cub Creek on Lone Oaks Farm does not touch a dam before it reaches the Gulf? What doesn’t ends up in lakes and ponds.
This is really cool info about the watersheds in Minnesota!
Rain falling on Minnesota can end up in three different oceans, and there is a single point in this state where all three watersheds meet.
That spot is called Hill of Three Waters, on the Laurentian Divide near Hibbing on the Iron Range. Stand there and a few feet in any direction determines whether water reaches the Gulf of Mexico, the Atlantic or Hudson Bay and the Arctic.
The southern and largest share drains to the Gulf. That is the Mississippi basin, starting at Lake Itasca and gathering the Minnesota River, the St. Croix and everything across the southern two thirds of the state. Water leaving Itasca takes roughly three months to reach the Gulf.
The northeastern wedge drains to the Atlantic. Everything on the Superior side of the Laurentian Divide runs down the North Shore into Lake Superior, then through the lakes, the St. Lawrence and out past Newfoundland.
The northwestern third drains to the Arctic. The Red River runs north along the North Dakota border into Lake Winnipeg, then the Nelson River carries it to Hudson Bay. The Rainy River and the Boundary Waters go the same direction.
That last one surprises people. Rivers in Minnesota flowing north is counterintuitive until you understand the land tilts that way in the northwest, a legacy of glacial Lake Agassiz.
The Laurentian Divide is the ridge separating Arctic drainage from everything else, and it runs across northern Minnesota through the Iron Range. Highway 53 crosses it and there is a marker.
The reason this happens here is glacial. Ice sheets scoured and deposited unevenly, leaving a landscape with barely any relief and three separate exits.
The whole state is basically flat.
And it still manages to feed three oceans.
