Basic Boating Rules

  1. Boat Permits: All watercraft require a valid Boulder Reservoir boating permit for use at the reservoir. Boat permits are available at the reservoir during regular business hours.
  2. All Boaters: All boaters are required to know and obey all safe boating rules and regulations at the Boulder Reservoir. This includes motor, wind or human-powered boaters.
  3. Safe Operation: Operating a watercraft in a reckless or negligent manner or in any way that endangers the safety of any person is prohibited.
  4. Alcohol: Alcohol is the number one contributor to boating-related accidents and deaths. Operating a watercraft while under the influence of alcohol or drugs is illegal.
  5. Obey Signs and Requests: Boaters must obey all regulatory signs and requests by lake patrol and reservoir staff.
  6. Colorado Boater Safety: Boaters are required to know and obey all current Colorado boating statutes and regulations. (See for more information).
  7. Personal Flotation Devices: All boats must be equipped with U.S. Coast Guard-approved personal floatation devices (PFDs) appropriate for each passenger. Wear your PFD! Accidents, cold water temperatures and sudden changes in wind or weather are leading causes of serious boating injures and deaths on mountain and Front Range waterways. Wearing a PFD can save your life.
  8. Report Incidents: Boaters must report all incidents that result in property damage or personal injury to the reservoir staff. Boaters are urged to report any incident of unsafe boating to staff as well.
  9. Your Responsibility: You are operationally and legally responsible for your safety and the safety of your passengers. Many boaters assume they are safe because they are experienced,
    are on a relatively small body of water or because they are good swimmers. Don't take your safety for granted - be aware of unsafe weather conditions and water temperatures, wear PFDs and operate your craft safely at all times.
  10. Weather: Wind and weather at the Boulder Reservoir can be unpredictable and change rapidly. Check boat launch area weather flags, current weather conditions at the reservoir's south gate and NOAA weather radio (for forecast) prior to boating. Be aware of cloud build up, sudden changes in temperature, wind direction or wind speed. Return to the marina or get to shore before weather becomes unsafe. Obey all weather warnings and safety closures.
  11. Clean Your Boat: All boats and water contact equipment must be thoroughly cleaned prior to entering the Boulder Reservoir to prevent the introduction of non-native aquatic species.
  12. Litter and Waste: Dumping, disposing of or discharging wastes or refuse, including human waste, in the water is prohibited.
