Chapter 4: The Legal Requirements of Boating
Obstructing or Impeding Navigation

Vessel operators should always be considerate of other vessel operators even when stopping to anchor or moor. Keep in mind that it is illegal to:

• Anchor a vessel in the traveled portion of a river or channel that will prevent or interfere with any other vessel passing through the same area.
• Moor or attach a vessel to a buoy, beacon, light, or any other navigational aid placed on public waters by proper authorities. Also, it is illegal to move, displace, tamper with, damage, or destroy any navigational aid.
• Obstruct a pier, wharf, boat ramp or access to any facility.
• Mark or obstruct the water of this state in any manner so as to endanger the operation of watercraft or conflict with the marking system prescribed by the Missouri State Water Patrol.
• Operate or otherwise position a vessel or other object or any person in such a
  manner as to obstruct or impede the normal flow of traffic on the lakes of this state.

Homeland Security Restrictions

Recreational boaters have a role in keeping our waterways safe and secure.

• Violators of the restrictions below can expect a quick and severe response.
  • Do not approach within 100 yards and slow to minimum speed within 500 yards of any U.S. Naval vessel. If you need to pass within 100 yards of a U.S. Naval vessel for safe passage, you must contact the U.S. Naval vessel or the U.S. Coast Guard escort vessel on VHF-FM channel 16.
  • Observe and avoid all security zones. Avoid commercial port operation areas, especially those that involve military, cruise-line, or petroleum facilities.
  • Observe and avoid other restricted areas near dams, power plants, etc.
  • Do not stop or anchor beneath bridges or in the channel.
• Keep a sharp eye out for anything that looks peculiar or out of the ordinary. Report all activities that seem suspicious to the local authorities, the U.S. Coast Guard, or the port or marina security.

In March, 2005, the U.S. Coast Guard officially launched America’s Waterway Watch to encourage the boating public to report suspicious activities in our nation’s ports and waterways. America's Waterway Watch simply asks anyone who works, lives, or recreates on the water to keep an extra eye out for any suspicious activities. Anyone who spots anything is asked to call the National Response Center's 24-hour hotline, 1-800-424-8802 or 1-877-24WATCH. The National Response Center is comprised of 16 federal response agencies that have various skills to respond to different incidents.

To Report Suspicious Activities: Call the National Response Center at 1-800-424-8802 or 1-877-24WATCH
