The U.S. Army Corps of Engineers' Little Rock District has started a new program for recreational boaters on 11 of the 13 Arkansas locks along the Arkansas River.
The Corps says all but the Trimble Lock near Fort Smith and the Ozark Lock at Ozark are closed to recreational boaters from 10 a.m. until 2 p.m. Monday through Thursday - with the exception of federal holidays.
The closings will allow for time to perform preventive and scheduled maintenance. The Corps says the Trimble and Ozark locks will be closed from 8 a.m. until noon each day to all river traffic so that maintenance work can be done.
Commercial towboats along with government and emergency response personnel will be locked through during the maintenance windows if the lock is operational.
