> It requires 200m litres of water to allow the passage of a single vessel along the canal, water that is largely generated from Lake Gatun in the centre of the waterway, which is drying up fast.

For context. The geography of the canal: https://upload.wikimedia.org/wikipedia/commons/9/91/Panama_C...

And a horizontal cross section of the canal: https://www.researchgate.net/publication/258387615/figure/fi...

Gatun Lake sits upstream of the sea, so they can't just open the locks to "fill" the lake.

This stands in contrast with the Suez Canal, which has no locks or elevation. It's nothing more than a long horizontal trench dug through the desert.

So, what the lake doesnt just feed the locks... It's the highpoint & something boats travel across.
