The Grand River watershed consists of approximately 12,000 square miles of runoff in parts of Kansas, Missouri and Oklahoma. Of that total, over half—7,000 square miles—is uncontrolled runoff, meaning there is no reservoir to control it above the Pensacola Dam. However, the remaining 5,000 square miles of runoff passes through the John Redmond Dam, located near Burlington, Kansas, prior to reaching the Grand River system in Oklahoma.

GRDA modifies Duck Creek boating rules

The Grand River Dam Authority is announcing some additional modifications to the new rules for boat operations in Duck Creek. The new rules, which went into effect prior to Memorial Day weekend are as follows (the latest modifications appear in italics):

• All watercraft legally trailerable (8.5 feet in width or less) and/or watercraft 30 feet or less in length, shall operate at a planing speed not to exceed 30 MPH. Boats must be up on plane or go slow, producing minimum wake.

• All other watercraft shall operate at slow speed, producing minimum wake.

• All watercraft must stay to the right of the buoys, and at least 150 feet away from docks and shore.

• Beginning May 1 and ending October 1, a no wake zone shall be in effect each night between 8:30 PM and 6:30 AM.

• Over the 4th of July weekend, all watercraft in Duck Creek must operate at slow speed, minimum wake round-the-clock (all day, all night).

 Questions concerning these rules, other lake rules, or lake safety issues can be directed to GRDA Lake Patrol Headquarters at (918) 782-9594.
