ANS Stamp FAQ's

Colorado is a Mandatory Boat Inspection State 

All trailered and/or motorized (gas or electric) watercraft are required to be professionally inspected by state-certified personnel: 

  • prior to launching in any water of the state after boating in a different state, 
  • upon exiting any water in the state which is positive for an invasive species, and 
  • any time an inspection is requested prior to entering or exiting a water body in Colorado.

Every boater is required in regulation to Clean, Drain, and Dry your boat, trailer and equipment every time you enter or exit any waters.
