DNR Violation Hotline

Wisconsin's Department of Natural Resources' Violation Hotline program provides Wisconsin citizens with the opportunity to confidentially report suspected wildlife, recreational, and environmental violations using a toll free number:

These violations may include fishing or hunting out of season, night hunting, exceeding bag limits, illegal sale of fish and wildlife, deposit of harmful substances in lakes or rivers, or illegal storage or disposal of hazardous waste. All these violations seriously affect our state's natural resources.

The hotline number is in operation 24 hours a day, 7 days a week. Trained staff relay reported information to our Conservation Wardens. Anyone who calls the hotline or provides information can remain anonymous.

Helpful Information when Reporting a Violation

When reporting a violation, please note as many facts as possible immediately. You will be asked a variety of questions. The more information you can provide, the quicker the violator can be caught, and the case successfully prosecuted. You should be prepared to furnish as much of the following information as possible:

• What was the violation?
• When and where did it occur? (county, township, road/highway)
• What weapons or equipment were used?
• What vehicles or crafts were used (registration numbers are important)?
• How many people were involved? (Do you know the people, their names, addresses?)
• Describe the people, including their physical description and clothing (backtag?).
• What evidence is still at the scene?
• Did the violator(s) take evidence of the crime with them?
• Which way or where did they go and how?
