Markland Locks and Dam (Ohio River mile 531.5): The lower approach has experienced shoaling as shown in the enclosed survey drawing. Tows with 7’ draft or greater are advised to use the Main (1200’) Chamber when the Markland lower gage is at 12.0’. Tows utilizing the Main (1200’) Chamber are advised to stay flat on the long wall (river-side approach wall) while entering and exiting the lower end of the locks to avoid the shoaling.

Mariners should make note of conditions, exercise caution when transiting the area, and take all directions from the Lock Operator.
