map of a watershed

A watershed is the area of land that drains to a particular lake, wetland or stream.

The City of Duluth is made up of many watersheds, all connected together like the pieces of a puzzle.

These watersheds don't end at the city limits, they are a part of the surrounding communities as well.


Watersheds

Watersheds, also called drainage basins, are made up of all of the land and water areas that drain toward a particular river or lake. Thus, a watershed is defined in terms of the selected lake (or river).

There can be subwatersheds within watersheds. For example, a tributary to a lake has its own watershed, which is part of the larger total drainage area to the lake.
