The Panama Canal, a vital passageway that moves 6 percent of the world’s maritime commerce, will extend transit restrictions due to drought-induced low water levels.
Canal authorities first announced restrictions this year, creating a backlog of vessels waiting to cross. But on Thursday, those restrictions were extended for at least 10 additional months.
Water from the Rio Chagres is used to fill the locks using gravity and afterward flows out both ends of the canal. As far as I’m aware the water is not ever pumped upward.
