Lock and Dam 14 Auxiliary Lock Sign

The U.S. Army Corps of Engineers, Mississippi River Project will open the Locks and Dam 14 auxiliary lock in Pleasant Valley, Iowa, for weekend recreational boating traffic beginning June 12 and running through Sept. 7.

The Auxiliary Lock will be available for recreational traffic Fridays from 4-10 p.m. and Saturdays and Sundays from noon-10 p.m.

On Friday, July 3, and Monday, Sept. 7, operational hours for the Auxiliary Lock will be extended to noon-10 p.m., to accommodate holiday boaters. The lock will also remain open until midnight Friday, August 14, allow for transiting boaters during the annual Tugfest event.

In addition, the Corps is no longer designating the three-mile channel, which extends upstream of the auxiliary lock, known as the LeClaire Canal, as a no wake zone. “No wake” buoys will no longer be placed in the canal and navigation charts will be modified to reflect the change. Boaters are advised to take caution when navigating the area and to be aware that federal and state regulations prohibit the movement of vessels at greater than no wake speed near anchored vessels and swimmers in the water.

As always, boaters are reminded to wear a life jacket when on or near the water. For more information call 309-794-5338 or visit
