They lift ships 85 feet over Panama with no pumps, only gravity and rainwater from Gatun Lake. Here's the Panama Canal lock system explained step by step: how ships go through the canal from ocean to ocean, and why drought keeps forcing it to cut traffic. Every day, dozens of ships climb over the Continental Divide in Panama. In this video we follow one across: why France's sea-level canal failed, how the U.S. built a lake 85 feet above the sea, how a lock chamber fills in about ten minutes, why the miter gates seal tighter under pressure, what the "mule" locomotives do, how the 2016 Neopanamax locks reuse 60% of their water, and why the 2023 and 2026 El Niño droughts cut daily crossings.
