A Climate-Resilient Future for the South Branch of the Chicago River

Shedd Aquarium is working alongside partner organizations and community residents to reimagine, research and rewild the South Branch of the Chicago River. This stretch of the river flows southwest from downtown through neighborhoods including Chinatown, Pilsen, Bridgeport and McKinley Park.

We Are Expanding Learning Opportunities and Recreational Access:

  • To explore the river ecosystem and identify ways our shared efforts with communities can help to address environmental and equity challenges.
  • To enable more Chicagoans to enjoy recreation like canoeing, kayaking, birding and fishing.
    • In 2022, Shedd welcomed over 250 area residents to a Chicago River Biodiversity Day event at Park 571 in Bridgeport for science activities, musical engagements and screen-printing by local teaching artists and organizations, kayaking, fishing and more.
    • Shedd facilitated canoe and kayak outings for about 100 nearby residents to experience the joy of exploring the river on the water.
  • Since 2018, Shedd has led kayak tours of the Wild Mile on the North Branch of the Chicago River to connect people to the innovative conservation work of Urban Rivers. Shedd has also provided financial support for the installation of floating wetlands and boardwalk on the Wild Mile.

We Are Improving River Health and Supporting Biodiversity and Climate Resiliency:

  • To create new habitat and bolster existing natural areas for wildlife above and below the water’s surface.
    • In 2022, Shedd installed over 3,000 square feet of floating wetland habitats with local nonprofit Urban Rivers and volunteers from the community.
    • Since 2017, Shedd has facilitated stewardship events at Ping Tom Memorial Park in Chinatown with community volunteers to remove invasive plants and litter and to support native biodiversity.
  • To support communities in stewarding and protecting natural resources, expanding native habitat and mitigating impacts of climate change such as flooding.

We Are Collecting Data and Monitoring River Ecology:

  • To build a shared understanding of habitat quality and wildlife populations.
    • In 2022, Shedd scientists found that a higher diversity of fish species spawn in the South Branch of the Chicago River, which we believe is due to the varied habitats found within Bubbly Creek and nearby unused barge slips.
  • To generate ecological and water quality data that guides future conservation efforts.
    • In 2023, Shedd researchers along with partners are tracking where fish move so we can better understand where key spawning grounds are as well as where fish overwinter during Chicago’s coldest months.

For generations, the Chicago River has been known as a polluted, neglected body of water. Starting in the mid-1800s, the river was heavily polluted by the slaughterhouses, steel mills, leather plants and others that dumped their industrial waste directly into the river. The river was also drastically changed as it was dredged, channelized and widened. Steel walls were installed in place of natural riparian shorelines in many areas. These changes to the river favored urbanization and industry uses over the needs and well-being of nearby communities and wildlife.

But, the Chicago River Is Resilient

The passage of the Clean Water Act in 1972 along with the efforts of local leaders, advocates and conservationists have contributed to drastic improvements to the health of the river. Today, more than 60 species of fish are known to live in the river — a huge increase from when the river’s water quality was at its worst. Many view it once again as a lifeblood flowing through our communities and city. More and more people are connecting with the river through kayaking, fishing, walking and dining along the river’s edge.
