Corps lowers Dardanelle pool to repair damaged lock gate

The Little Rock (Ark.) Engineer District has begun lowering the Dardanelle pool on the McClellan-Kerr Arkansas River Navigation System (MKARNS) to elevation 336 feet to support repairs to a damaged miter gate at Dardanelle Lock and Dam.

The drawdown began November 26 and will take about two days to reach the target elevation from the current 337.8 feet. The 336-foot level is within the project’s normal operating range.

The lock will remain closed for approximately two weeks while crews repair the gate. The Corps said it has coordinated the closure with navigation stakeholders.

The miter gate was damaged November 21, when the downbound M/V St. Bartholomew, owned by Marquette Transportation, struck the structure, forcing an immediate shutdown of the lock.

The Corps said the incident highlights the importance of the MKARNS system, which supports regional commerce, national supply-chain reliability and long-term economic resilience. The agency said it remains committed to maintaining the system’s reliability for the communities and industries that depend on it.
