IA DNR conservation officers have the authority to enforce the boating laws of Iowa. The USCG also has enforcement authority on federally controlled waters.
- Officers have the authority to stop and inspect a vessel being launched, being operated, or being moored on Iowa waters to determine whether the vessel is properly registered, numbered, and equipped.
- Officers may board a vessel in the course of an inspection if the operator is unable to supply visual evidence that the vessel is properly registered and equipped.
- It is illegal to fail to bring your vessel to a stop, or to attempt to elude an officer, after being given a visual and audible signal to stop. An officer may signal you to stop by displaying a blue light or flashing blue and red lights, or by sounding a horn or siren.
