Geography
The Amacuzac River is one of the most important tributaries of the Balsas River. It originates on the slopes of the Nevado de Toluca, in the State of Mexico, where it is known as Texcatitlán River. The Amacuzac River runs through the valley of Almoloya de Alquisiras, after 75 km it reaches the Sierra de Cacahuamilpa, then it disappears at the foot of Jumil Hill and turns into an underground river.

When it emerges the current is known as the Amacuzac River, in the territory of the state of Morelos. The Cuautla River empties into the Amacuzac River and crosses the town of Amacuzac.
