Below you’ll find information ranging from the basin’s history to its recent threats.
Milwaukee River Basin
Milwaukee River Basin is located in portions of seven counties, contains (entirely or portions of) 13 cities, 32 towns, 24 villages and is home to about 1.3 million people.
Milwaukee's Sewers & the Rivers
The City of Milwaukee began construction of a public sewer system more then 130 years ago, to carry wastewater to the area rivers and to Lake Michigan.
There are approximately 3,800 dams in existence in the State of Wisconsin. Since the late 19th century, more than 700 dams have been built, then washed out or removed.
Contaminants & Polluntants
The Clean Water Act defines "pollution" as the "man-made or man-induced alteration of the chemical, physical, biological, or radiological integrity of water."
In Milwaukee we’re lucky to have an abundance of water. This basin is home to 1000 miles of river and bordered by Lake Michigan, which contains over one trillion gallons of water.
