Who controls docks on Grand Lake?

Grand Lake O' the Cherokees was created by Pensacola Dam on the Grand River, completed in 1940. GRDA calls it the world's longest continuous multiple arch dam and Oklahoma's first hydroelectric facility, and says the lake covers 46,500 surface acres. GRDA was created by the state in 1935 and manages the lake, so dock permits come from GRDA rather than the Corps of Engineers. Its lake rules are published in Title 300, Chapter 35 of the Oklahoma Administrative Code.

What goes in a private dock application?

Scaled drawings on graph paper with all dimensions, including walkway and slips
Written driving directions to the site by land and by water
A deed showing the applicant owns the adjoining land, plus company documents if an LLC or company owns it
An original, stamped survey by an Oklahoma licensed land surveyor showing the property line and GRDA's taking line, with corners marked on the ground
An electrical certification form if the dock is wired, and engineered drawings if GRDA asks for them
The current permit fee from GRDA's fee schedule; the permit carries an annual fee

GRDA returns applications that are missing items. After installation, the applicant notifies GRDA that the dock is in, and the lake rules call for a GRDA inspection before the permit is issued.

How are size and placement limited?

A dock may not extend more than one third of the cove, measured perpendicular from where the walkway meets the 745-foot Pensacola Datum elevation to the nearest shoreline at that elevation, and it may not reach farther than needed for appropriate depth. The dock edge must stay at least 5 feet from the property line, and walkways can't connect to another dock in a way that restricts the shoreline. For docks parallel to shore, the open end must be 1.5 times the slip length from the property line. A boat moored at a private dock for more than 72 hours has to be kept in a slip.

What are the flotation, anchoring and electrical rules?

Flotation must be commercially manufactured for marine use and must not waterlog, crack, peel, fragment or lose beads. Foam must be fully encased; GRDA defines encapsulated flotation as expanded polystyrene in high-density polyethylene at least .150 inch thick on the bottom and .125 inch on top, and new construction may not use non-encapsulated white foam. Anchors on GRDA property are limited to a sleeve near-ground anchor or a saddled anchor, and trees on GRDA land can't be used. Electrical systems must follow the National Electrical Code, with a clearly labeled disconnect above the high water mark. Submersible pumps aren't allowed in the water, permanent service needs GRDA's written approval, and temporary supply isn't allowed.

What about changes, moves and sales?

GRDA's lake rules require permission before any modification, change, addition or improvement to a dock, and relocating or transferring a dock also needs a permit. A sold dock goes through a transfer application, the permit number moves to the new owner, and a new electrical certificate is required. Permit holders may sell a dock outright but may not lease, rent or sublet it for commercial use, and habitable structures on docks are prohibited.

What about retaining walls and riprap?

Shoreline work has its own GRDA application covering retaining walls, boat ramps, tram systems and riprap. GRDA's flowage easement standards say no construction may begin on GRDA property or in the flowage easement without written approval, list banned materials such as railroad ties, tires, broken concrete and creosote timbers, and note that work below 745 feet needs a U.S. Army Corps of Engineers Section 404 review.

Common questions

Who issues dock permits on Grand Lake?

The Grand River Dam Authority. Contact its lake permitting office at lakepermits@grda.com or (918) 256-0852.

How far can my dock stick out?

No more than one third of the cove, measured at the 745-foot Pensacola Datum line, and no farther than needed for adequate depth.

Does the dock permit transfer when I sell?

GRDA uses a transfer application to move the permit number to the buyer, and a new electrical certificate is required.
