A large crack measuring at least 3 meters is currently draining the water into the very touristic Xochimilco canals in Mexico City.
The water level has locally already considerably decreased.

A large crack, measuring at least 3 meters, opened up at the bottom of a canal in Xochimilco, Mexico, suddenly draining large quantities of water into the ground.

It is on Tuesday at dawn that baffled residents watched the water level decreasing. The fissure is located in the area of channel 27 Zacapa. Water is however still abundant enough in the touristic and production areas.

The National Center for Disaster Prevention and the Institute of Geophysics are now investigating the still unknown cause of this geological event.

Last year, the Atoyac River as well as two other streams suddenly disappeared in huge sinkholes in Mexico.

Here a video for people speaking spanish:
The crack should be filled up in the next days. The Xochimilco channels are a great touristic attraction near the center of Mexico City. Among others, you can visit the mysterious Island of Dolls.
