Aquatic Nuisance Species (ANS)

Stop Invasive Species.  CLEAN. DRAIN. DRY. (logo)

As soon as you pull your boat out of the water, remember to:


Pressure wash your boat, trailer and equipment with hot water (140º F) and remove all zebra mussels, plant fragments and mud that are visible.


Drain all water from your boat, motor, bilge, live wells, coolers and ballast.


If pressure wash is not available, allow the boat, trailer and equipment to dry thoroughly for at least five days before visiting a new water body.

Attention Anglers

Bighead and silver carp are invading Oklahoma waters. If you catch either of these species, do not release the fish back into the water. Report it to Wildlife Department personnel immediately by calling (405) 365-5060. Anglers are allowed to possess dead or live bighead and silver carp when reporting them to the Wildlife Department. The Wildlife Department is collecting biological data on these species to better understand their population status and the threats they pose to state lakes and rivers. Your cooperation is appreciated.
