a boat on the water

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Taking to the water in your power boat, sailboat, jet ski​, or canoe is a great way to enjoy Colorado’s many waterways.

Whether you're swimming or boating, it's important to use common sense while you’re out on the water. The Colorado Boating Program helps you get underway safely while enhancing your boating experience.

Registration is required for all power boats and sail boats operating on Colorado waters. Boating incidents that result in injury or death, or damage beyond $500 must be reported using a Boating Incident Report Form.

Aquatic Nuisance Species Stamp Required

Motorboats and sailboats must have an ANS Stamp prior to launching in Colorado.

Boat owners are required to purchase the ANS Stamp and operators must retain proof of purchase (electronic or printed receipt) on his or her person, the motorboat or sailboat, when operating the vessel (C.R.S. 33-10.5-104.5). 

  • Motorboats and Sailboats from Colorado - $25.00
    • Colorado residents will purchase the ANS stamp at the time of registration. ​If you register/renew your vessel online or via a registration renewal postcard, the cost of the ANS stamp appears as part of your total amount due. You do NOT need to manually add another $25 to your payment for the ANS stamp.​
    • Residents with motorboats or sailboats documented by the U.S. Coast Guard or otherwise exempt from in-state registration can purchase the ANS stamp online at​, or at any CPW office or sales location.​
  • ​​Motorboats and Sailboats from Another State - $50.00 
​Funding contributes to prevention and management of ANS in the state. To learn more about the ANS stamp, visit our Frequently Asked Questions document. Thank you for protecting our waters and contributing to conservation in Colorado!
