Lake Rules and Regulations

This is a guide to answer frequently asked questions concerning lake rules. Complete rules and regulations in PDF format GRDA Lake Rules 8-11-19. Lake rules are also available at GRDA’s Lake Patrol office and most marinas.

All relevant Oklahoma laws, as well as the GRDA Lake Rules and Regulations, apply to all GRDA lakes. Failure to comply with these may be a criminal offense.

All vessels must have Oklahoma registration and license by June 30 each year. Boats currently registered in another state may be used on these lakes for a 60-day period without registering them. If the boat remains in Oklahoma for more than 60 calendar days, it must be registered in Oklahoma. Registration stickers must be displayed on the front port and starboard portion of the vessel.

All boats kept or operated on GRDA lakes shall be inspected by GRDA’s Police. A safety inspection sticker shall be placed on the port front portion of boat. This is a free inspection.

Kyle Williams Boating Safety Education Act

The Kyle Williams Boating Safety Education Act prohibits kids between the ages of 12 and up to 16 years old, without a valid drivers license, from operating any vessel powered by a motor of more than 10 horsepower or a sailing vessel 16-feet or longer without first completing a state approved Boater Safety Course.

They must also have a certificate documenting their completion of the course. Fines for violating this new law range from $50-$500. Our goal is to help you make sure your family is safe while having fun and in compliance with the law.

Safety First Around Our Dams

Safety around its hydroelectric facilities is a top priority for the Grand River Dam Authority.  Signs, buoys, sirens, fencing and flashing lights are all intended to notify those in the area when floodgates are open, generators are operating or water is rising swiftly.

Signs – Posted at GRDA hydroelectric facility (Pensacola Dam, Robert S. Kerr Dam, and the Salina Pumped Storage Project) to warn of extreme danger in floodgate areas. Please be aware of other signs near GRDA facilities that notify you of no trespassing areas, no diving areas, or unstable footing.

Buoys – Red buoys and cabling above and below spillway gates and hydroelectric powerhouse restrict access to dangerous areas associated with power generation or floodgate releases.

Flashing Lights – At hydroelectric facilities, the flashing lights are initiated when floodgates are opened or generation is initiated.

Fencing – In place to identify borders and to restrict access to certain areas near the hydroelectric facilities.

Sirens – These are located at various locations on the hydroelectric facilities and are utilized prior to the operation of hydroelectric generators and/or floodgates.

Grand Lake Lighthouses – As navigational aids, several lighthouses are located on Grand Lake, around the shoreline and in areas of shallow water.  The Grand River Dam Authority has an ongoing maintenance program in place to ensure the lighthouses are functioning properly.

If you have concerns regarding the lighthouses on Grand Lake, please contact GRDA at 918-256-0644.
