Panama Canal begins dry‑chamber overhaul of historic Gatun locks

The Panama Canal Authority started a scheduled dry‑chamber maintenance project on the Gatun locks, the oldest of the canal’s five lock complexes. Workers temporarily emptied a lock chamber to replace six valves and refurbish gates 33 and 34, a job expected to last eight to nine days.

The work is part of the canal’s $500 million‑a‑year general maintenance program, aimed at preventing water loss – each lockage can waste 55 million gallons – and to prepare the system for the upcoming El Niño climate pattern. The Gatun locks handle roughly 3 %–6 % of global maritime trade, making their reliability critical for international shipping.

Engineers emphasized the importance of the repairs, noting that the original gates were fabricated on site a century ago and that keeping the valve system in good condition helps conserve water for Lake Gatun and the nation’s water supply.
