Gatun Lake Water Levels, Panama Canal

Water Level Transportation Indicators

Our Gatun Lake water level chart provides essential data for Panama Canal shipping and agriculture. The visualization presents daily historical lake level measurements alongside seasonal patterns and official Panama Canal Authority (ACP) projections. Gatun Lake's level determines the maximum authorized transit draft for Panamax and Neopanamax vessels, so the projected draft limits section below shows how forecast lake levels translate into draft restrictions and surcharge percentages. Water levels are recorded in feet, the convention used by the ACP. Data is sourced from the official Panama Canal Authority EVTMS reports with daily updates.
