Waterways & Wetlands

On these pages, you can learn how Wisconsin laws protect public waters and how you can help. You'll also find information to determine if a permit is needed for a project and links to instructions and forms to help you apply for a permit.

This Web site provides information, factsheets and application materials regarding Wisconsin's Waterway and Wetland permit requirements.

Wisconsin's public water regulations have been in place for decades. The program is founded on the Public Trust Doctrine, the body of law made by the Legislature and the courts that guides how DNR protects public rights in navigable waters.

Early in 2004, Wisconsin Act 118 was passed by the Legislature and signed by the Governor to speed permit decision making while maintaining the state's long-standing level of protection for public waters. Chapter 30, Wisconsin Statutes (PDF, exit DNR), was revised by the act. Learn more about these rights and how Wisconsin citizens fought to secure them by viewing this preview of Champions of the public trust.

On May 1, 2005, new rules went into effect to implement the statute changes. These rules maintain Wisconsin's longtime commitment to protect public lakes and streams as guaranteed by our State Constitution. A growing body of research in Wisconsin and elsewhere documents that small changes to the shoreline affect water quality and fish and wildlife habitat - and add up to harm the diversity and abundance of fish, songbirds and frogs, and make our waters vulnerable to invasive species. The shallow water and shoreline habitat protected by the permit system is the keys to continuing Wisconsin's great fishing, clean water and natural scenic beauty. Our $12 billion tourism economy, our environment, and our lifestyle depend on it.

For a specific project in or near a waterway or wetland, you can find advice, application materials and contacts by choosing an activity from the list located along the left side of your screen. Most of our forms and brochures are available at this Web site but a few infrequently-used materials need to be obtained by contacting a Wisconsin DNR Service Center or Regional Office.
