9 Awesome Reasons to Book a Cruise Through the Panama Canal


8. To Fully Understand How it Works

Wrapping your mind around just how the locks in the canal work can be tough if you haven’t experienced them for yourself. There are three sets of locks: 1 on the Atlantic side, 1 on the Pacific side, and 1 connecting Gatun and Mira Flores Lakes. The purpose of the locks is to raise and lower the water level in each chamber using water from the lakes, and thereby allow ships to pass through what used to be solid earth. The sheer amount of water it takes to get just one ship through the canal – 26,700,000 US gal (101,000 m3) times 12 lock chambers – is staggering. All of the water comes from natural runoff into the lake and empties out into the ocean through the process. In wet, winter months, there’s plenty of water to go around. In the dry season, however, Gatun Lake may experience a shortfall.
