  1. All Colorado State boating statutes and regulations, City of Boulder revised code and Boulder Reservoir rules and policies apply and are enforced by reservoir lake patrol, urban rangers, Boulder Police Department (BPD), and Open Space and Mountain Parks (OSMP) rangers. Violators may be ticketed. Please visit the Colorado State Parks website or call 303-791-1954 for more information.
  2. All watercrafts must display a current City of Boulder Reservoir permit. Reservoir permit must be placed on the port (left) side of watercraft hull. Permit must be applied to vessel by Reservoir personnel only!
  3. All watercraft (including, but not limited to, sailboats, powerboats, kayaks, canoes, paddle boards, inner tubes, water-skis, wakeboards, flotation devices, etc.) must be inspected upon entry into and exit from the park, even if the item will not contact the water or be used. All watercrafts may only be launched from the south shore after successful completion of an ANS inspection! At no time can any watercraft touch, launch from, or be moored on the North Shore.
  4. Reservoir pattern is always counterclockwise, (keep buoys on starboard [right] side, and rafts on port [left] side). See Reservoir Boating Map.
    • Full lap counterclockwise around all center rafts; at least 150 feet from shoreline.
    • Half lap (north or south) counterclockwise around lake, and in-between row of center rafts and centerline buoys (buoys on starboard side, and rafts on port side).
  5. All watercrafts must remain “wakeless” or maintain a maximum speed of 5mph or less within all “NO WAKE” buoys and mooring areas.
    1. “The term “wake” means a movement of the water created by a boat underway, great enough to disturb a boat at rest.”
  6. No Wake Hours: See our website for the most updated no wake hours. Additional days and times may be added for specific events (see event calendar).
  7. Tuesday and Thursday will be designated limited wake days. Outside of no wake hours boats will not be permitted to create an excessive wake. Typically, excessive wakes are created by boats that have filled ballast tanks for activities such as wake surfing and foiling.

The observer is responsible for prominently displaying the skier advisory flag (12” x 12” fluorescent orange or red flag).

The flag then MUST be lowered when the towed person(s) is either back in the boat or have resumed being towed. 12.
