Water defines Milwaukee, whether it’s vast Lake Michigan to your east, the rivers and tributaries that feed it, landscaping features designed to absorb rain and runoff, or the underground pipes and chambers that manage storm and waste water. Fund for Lake Michigan invites you to use the Virtual Doors Open water passport to explore the relationship between Milwaukee’s water and the city’s industrial, commercial, civic, and residential development. Some sites this year are part of the Plastic Free MKE coalition who are dedicated to keeping our rivers and Great Lakes free of plastic.

The Doors Open Water Passport and Harbor District App were made possible with support from the Fund for Lake Michigan.  Special thanks to Milwaukee Community Map for providing the mapping on this year's Water Passport. Learn more about Milwaukee Community Map.

Featured Water Passport locations can be found on the watershed map below, or open in a new window for ease of viewing. The area of land that drains to a body of water is called a watershed. Milwaukee's three rivers are the Milwaukee, the Menomonee, and the Kinnickinnic, each has its own watershed! Learn more about watersheds.

Plastic Free MKE Map

Plastic-Free MKE's mission is to reduce the harms that unnecessary plastics have on environmental health, public health, and social justice.

Our rivers and Great Lakes are feeling the impact of the plastic epidemic, and it is threatening the health of aquatic wildlife and our communities.

Passionate community members, small business owners, engineers, agencies, local non-profits—all make up the Plastic-Free MKE coalition.
