Fish farming in WisconsinNatural waterbody permitting

A permit is required from the Department of Natural Resources (DNR) for any DATCP-registered fish farm to use a natural body of water for their aquaculture operation. Section 29.733, Wisconsin Statutes establishes the permit program, and NR 19, Wisconsin Administrative Code explains the permit process and requirements for operating a fish farm in a natural body of water.

A waterbody that was licensed by DNR on January 1, 1998 as a private fish hatchery may be eligible for a Grandfathered NR 19 permit. Otherwise, the use of a natural body of water for fish farming is limited to freeze-out ponds, and requires an Initial NR 19 Permit. Under the Initial NR 19 permit review, a permit is only issued if DNR determines that no substantial public interest exists in the body of water and that no public or private rights in the body of water will be damaged. If a property is sold, a permit is required to transfer an NR 19 permit to the new owner.

To apply for an NR 19 permit, fill out Form 3600-227 [PDF] and submit it along with the necessary attachments to your local Fish Farm Environmental Permits Coordinator.

Public notice on permit applications

The DNR will post a notice of every natural waterbody permit application on its website according to 2011 Wisconsin Act 207. If no substantive written objection is received by 30 days after posting, the DNR may grant the application without a public hearing. Permits will be granted if the DNR finds that no substantial public interest exists in the waters and that no public or private rights in the waters will be adversely impacted. Public rights include plant and wild animal habitat or populations; water quality and quantity in lakes, streams or rivers, threatened or endangered species or their habitats, wetlands and the public’s right to navigate and associated incidents to navigation including fishing, swimming, wading and canoeing. Because all navigable waterbodies in the state belong to the public, state law requires the DNR to request if anyone has objection to the permit.
