The Panama Canal, operational since 1914 and with an expansion in service since 2016, is the only one in the world with fresh water. It is supplied by Gatún and Alhajuela lakes, created in 1913 and 1935, respectively. In Lake Gatún are eight water treatment plants that supply half of Panama's four million inhabitants. Nelson Guerra, hydrologist supervisor, explains that the useful water volume in Gatún, at its maximum operational level, is around 1,200 cubic hectometers, while in Alhajuela it is 500 cubic hectometers. The water savings account of the canal, according to Guerra, is similar to a person's, where water is accumulated for different uses. The Gatún level was just over 84 feet or 25.60 meters last Wednesday, a level below the 89 feet optimal that allow the canal to offer its maximum draft. Due to the El Niño effect, the canal has begun to apply water-saving measures, such as a restriction on daily transits and a reduction in draft. The canal projects the construction of a new reservoir in the Indio River, which is expected to be operational by 2032, to guarantee water for 50 years to the canal and the population. Three limnographic stations monitor the level of Gatún, while 58 hydro-meteorological stations along the Canal Watershed monitor precipitation, the levels of the main tributary rivers of the reservoirs, and tides, among other things. All are interconnected in a real-time telemetry system,
