Law Enforcement

The U.S. Fish and Wildlife Service maintains a law enforcement presence on National Wildlife Refuge lands.

The mission of the National Wildlife Refuge System Law Enforcement program is:

"Through Education and enforcement we protect our employees, volunteers, and visitors; safeguard the public’s investment in facilities and equipment; and protect the integrity of the habitat and the wildlife resources of the National trust resource which is the 150 million acre National Wildlife Refuge System.”

Federal law enforcement officers ensure the safety of the public and the protection of natural resources. They address illegal activities, including poaching, taking of endangered species, dumping of trash, illegal operation of all terrain vehicles, trespassing, vandalism, and more.

To report a violation on Bill Williams River National Wildlife Refuge:

You can contact Refuge Headquarters at (928) 667-4144 from Monday to Friday 8:00 am to 4:00 pm 


contact the Phoenix Interagency Dispatch at 1-800-637-9152. This number is available 24/7.

 In case of an emergency call 911.

Timely reporting of crimes is important to reducing crime on the refuge. When calling in a violation please remember to provide as much information as possible including, who (persons and vehicles involved), what happened and how, when, and where the crime took place. If you have a camera available and it is safe to do so please take a picture of the event and share it with us.
