Note: Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the "§404 permit/§401 certification process." This process involves the U.S. Army Corps of Engineers and your state environmental agency. To learn more about the wetlands permitting process go to the CICA Wetlands Regulations/Permit page.

Primary State Wetlands Web Page. This web page should explain the state wetlands program and provide links to various wetlands resources.

Construction Permit Process - State Rules

    How Are Wetlands Activities Regulated by Wisconsin? Wisconsin has recently enacted legislation regulating isolated wetlands. The Department of Natural Resources (DNR) will regulate discharges into wetlands, as well as issue certificates for discharges that comply with all applicable state and federal water quality standards.

Regulatory Definitions
    Wetlands. Wetlands are areas where water is at, near or above the land surface long enough to be capable of supporting aquatic or hydrophytic vegetation and which have soils indicative of wet conditions. The state currently maps wetlands that are five acres or more.

    Wetland Categories. Areas of special natural resource interest include wetlands within the boundary of designated areas of special natural resource interest and those wetlands in proximity to or have a direct connection to such designated areas. These areas are recognized by the state as having special ecological, cultural, aesthetic, educational, recreational or scientific qualities.

    Regulated Wetland Activities. Any discharges of dredged or filled material into a wetland that is not subject to federal regulation after the SWANCC decision are covered by the new law.331 The discharge of dredged and fill material is prohibited unless authorized by the Department of Natural Resources (DNR). Certified activities must have only a minimal adverse environmental impact when performed separately or cumulatively.

    Exempt Wetland Activities. Activities exempt under the federal law are exempt under Wisconsin law. Exemptions also apply to normal farming, silviculture, and ranching activities; the construction and maintenance of farm ponds, stock ponds, or irrigation ditches; the maintenance of ditches; and the construction of farm and forest roads.
