If you plan to be on the water this weekend, keep in mind there will be some temporary restrictions in effect on Saturday. Boat races are scheduled from 9am until 5pm. Boating traffic will be restricted to idle speed from the five mile mark to the nine mile marker, extending to the half-mile mark of the Gravois arm. Those restrictions will be in place until about 30 minutes after the final race ends. The Water Patrol says you should expect a lot of congestion in that part of the lake and exercise extreme caution during and immediately after the races.
