SPRINGFIELD, IL — Today, the Protect Illinois Waters Coalition celebrated as the Illinois House Energy and Environment Committee advanced House Bill 3596, the Wetlands Protection Act, out of committee—marking a critical step toward restoring protections for Illinois’ most vulnerable wetlands.
“This is a critical step toward closing a dangerous gap in protections for Illinois wetlands,” said David McEllis, legislative director at the Environmental Law and Policy Center. “Our state is relying on a patchwork system that leaves many wetlands vulnerable to destruction. Today’s vote shows lawmakers recognize the urgency of protecting our water, our ecosystems, and our communities.”
Illinois has already lost 90% of its historic wetlands, and recent federal policy changes have made the situation more urgent. Following a 2023 U.S. Supreme Court decision and subsequent Trump admin federal rule changes, an estimated 72% of Illinois wetlands are no longer protected under the Clean Water Act—leaving hundreds of thousands of acres at risk.
“We can’t afford to lose the protection wetlands provide,” said Illinois Rep. Anna Moeller. “Clean drinking water, flood protection and other wetland benefits are simply not negotiable – they are necessary for all of us. I’m proud to sponsor this legislation in the House this spring.”
The Wetlands Protection Act (HB3596/SB2401) is designed to fill that gap by empowering the Illinois Department of Natural Resources to oversee wetland permitting and establish clear, science-based standards for protection and mitigation.
“Our wetlands are too precious to not protect,” said Emily Kowalski, associate director of Environment Illinois. “Today’s action clearly recognizes that now is the time to protect our wildlife and clean water by protecting Illinois’ wetlands.”
Illinois’ remaining wetlands are especially vulnerable to destruction, creating urgency for state action. The legislation would establish a state-level permitting program to regulate activities like dredging and filling in wetlands, ensuring that development does not come at the expense of clean water, flood protection, and wildlife habitat.
“Wetlands play an essential role in protecting communities and the environment, especially from flooding,” said Paul Botts, president and executive director of The Wetlands Initiative. “Wetlands absorb floodwaters, filter pollution from drinking water sources, and provide habitat for endangered and native species. The vast majority of our historic wetlands have already been lost, and without action, many of our remaining areas are left unprotected and at risk of irreversible damage.”
Today’s committee passage follows growing momentum from advocates across Illinois who have mobilized to support stronger wetland protections, including petitions, public comments, and in-person advocacy at the Capitol.
“This win belongs to the thousands of Illinoisans who are speaking up, showing up, and demanding action to protect Illinois’ endangered wetlands,” said Lindsay Keeney, IEC program officer, conservation and sustainable agriculture. “Our work is not done; we will continue to fight for the legislative, agency, and executive level support needed to get wetlands protections passed.”
Environmental advocates will continue working to advance the Wetlands Protection Act through the full House and Senate and urge lawmakers to act swiftly to protect the remaining wetlands across the Prairie State.
