Waterway protection

NOTES ON WATERWAYS PERMITS

For each project type below, if an exemption or a general permit is available, you will find a link to a checklist of requirements. If your project does not meet exemption eligibility criteria, review the general permit checklist. If your project does not meet general permit eligibility criteria, you must apply for an individual permit.

To start a permit application, use the DNR Water ePermitting System. A WAMS ID is required.

For some waterway projects, a water quality certification (WQC) may be required from DNR as the certifying authority under the Clean Water Act Section 401. WQC requests will be considered complete through a waterway permit application and the DNR Waterways Program typically reviews WQC requests in parallel with permit review. See WQC Request Completeness Elements for the full list of requirements.

To determine if a local permit or a federal permit is required for your project, contact your city or county zoning authority and the U.S. Army Corps of Engineers – St. Paul District Office.

State law requires a landowner with a project site that is 1 acre or larger in size to obtain a construction site stormwater permit. To submit a notice of intent, visit the DNR Stormwater Runoff Permitting page.

Applicable state statutes and code: s. 30.12, Wis. Stats. and NR 323, Wis. Adm. Code.

Ponds

Maintenance of Existing Ponds

Removal of weeds, invasives, or nuisance plant species by hand does not require a DNR permit, but vegetation control using chemicals (herbicide) requires a DNR Aquatic Plant Management permit.

Maintenance of a previously permitted pond that does not change the size or footprint of the pond does not require a DNR permit. Dredging maintenance of a pond may be exempt but the dredged material should not be placed in wetlands and should be placed in an upland area. If you propose to discharge dredged material into wetlands, you likely need to apply for a wetland permit.

If your pond was not previously permitted and is connected to or located within 500 feet of a navigable waterway or located in a wetland, you likely need an individual permit. See the Do I need a Permit decision tool below.

New Ponds and Pond Enlargements

A DNR permit is required to construct, dredge, or enlarge a pond or artificial waterbody if it is:

connected to a navigable waterway.
constructed within 500 feet of a navigable waterway.
constructed in a wetland, including wetland restorations that result in ponds.

A pond is considered connected to a waterway if it discharges into the waterway during normal flow conditions outside of storm events through any channel or drainage whether it's natural or artificial, open or closed.

Please note that pond projects must avoid wetlands to the greatest extent practicable, meaning if there is an upland area on the property it will be difficult to justify constructing a pond in a wetland area. Storm water and landscape ponds are not eligible for a general permit in wetland areas. Wildlife ponds are typically only eligible in wetlands for the purpose of restoration or enhancement if the wetlands are degraded and dominated by agricultural crops or invasive species.

Do I Need a Pond Permit?

This is a text version of our ponds interactive question and answer module to help you understand if you need a permit for your project. If you are seeing this message, you currently have JavaScript disabled or are in compatibility mode while using Internet Explorer. This text version is here to help you understand if you need a permit from the Wisconsin Department of Natural Resources for your project, and if so, which one. Please go through and answer each question. This will help you determine which permit you will need.

Question 1:

Please describe your project:

If your answer is "I would like to build a new pond" go to Question 16.

If your answer is "I would like to do some work on an existing pond" go to Question 2.

Question 2:

You've answered Yes.

If your answer is "Yes":

If your project is for wetland conservation, you may able to seek general permit coverage to construct a wildlife pond. Otherwise, you will need to apply for an individual pond permit.*Please note: WAMS ID and password needed to apply. If you do not have a WAMS ID, you must register for one prior to proceeding.

FISH HABITAT STRUCTURES

Permitting requirements for fish habitat structures depend on the proposed size of the structure, whether the waterway is a stream, lake, or Great Lake, and whether the waterway has a special designation.

Several project types have specific exemption criteria which are listed in the checklists below. Any project proposed in an Area of Special Natural Resource Interest (ASNRI) or a Public Rights Feature (PRF) requires a DNR permit. See the Fish Habitat Structures General Permit Checklist for specific size and placement requirements for each structure type. If your project does not meet general permit eligibility, or if the type of structure you plan to place in a waterway is not listed below, you must apply for an individual permit.

If your project was designed by DNR, Natural Resources Conservation Service (NRCS), U.S. Fish and Wildlife Service, or county agency staff, you may be eligible for a general permit for fish habitat placement. Review the Stream Habitat Projects Designed by Government Agencies General Permit Checklist (3500-174) for further details.

Permitting Options

Fish Cribs

Fish Sticks

Half Log

Spawning Reef

Tree Drop

Net Pen

Wing Deflector

WILDLIFE HABITAT STRUCTURES

A bird nesting structure may be exempt from needing a permit if it is not proposed to be placed on a waterway designated as an Area of Special Natural Resource Interest (ASNRI) or a Public Rights Feature (PRF) and the surface area of the structure is 25 feet or less. A structure placed in an ASNRI or PRF waterway may be eligible for a general permit if it has a surface area of 25 feet or less. If your project does not meet exemption or general permit eligibility criteria, you must apply for an individual permit.

Wood duck houses and nesting platforms attached to or supported by existing trees in their natural condition do not need permits.

If your project was designed by DNR, Natural Resources Conservation Service (NRCS), U.S. Fish and Wildlife Service, or county agency staff, you may be eligible for a general permit for wildlife habitat placement. Review the Stream Habitat Projects Designed by Government Agencies General Permit Checklist (3500-174) for further details.
