VINITA – The Grand River Dam Authority is announcing that the new and revised lake rules and regulations for Grand and Hudson Lakes are in effect, as of June 25. After a public comment period early this year, the GRDA Board of Directors approved the new rules which were then approved by the Oklahoma Legislature and Governor Brad Henry. The rules carry the force and effect of law.

While hardcopies of the rules will soon be available to the public at various locations around Grand and Hudson Lake, the public can now view the rules online at Just follow the “Lake Rules” link under the “Lake Management” dropdown menu on the homepage. For more information, contact GRDA at (918) 256 5545.

While the most significant revisions are related to the new GRDA Ecosystems and Education Center (as the location for all lake permitting), there is one significant revision under the “boater safety” section of the rules. The new “night speed limit” rule reads as follows: “It shall be unlawful for any person to operate any vessel upon the waters of GRDA, between the hours of one-half hour after sunset and one-half hour before sunrise at any speed in excess of twenty-five (25) miles per hour.”

The former night speed limit was 35 MPH.
