Panama Canal Locks Quiz – Lifting Ships Across Panama

The Panama Canal opened in 1914, linking the Atlantic and Pacific oceans. Ships climb through locks to Gatun Lake, an artificial lake about 26 meters above sea level created by damming the Chagres River.

The original locks are Gatun on the Atlantic side and Pedro Miguel and Miraflores on the Pacific side. Electric locomotives called mules guide ships, and the chambers set the Panamax size limit.

In 2016 the expanded Neopanamax locks, Agua Clara and Cocolí, opened with rolling gates, tugboats and water-saving basins. Panama took full control of the canal at the end of 1999, and droughts have recently forced limits on transits.
