Zanjón de la Aguada, Canalised brook in Santiago, Chile

The Zanjón de la Aguada is a 27 km canalized watercourse that runs east to west through Santiago. It collects water from the Quebrada de Macul and crosses the communes of Macul, La Florida, San Joaquín, San Miguel, Pedro Aguirre Cerda, Santiago, Cerrillos, Estación Central and Maipú before emptying into the Mapocho River. Its banks include the Parque Intercomunal Víctor Jara, a floodable green area built between 2013 and 2017.

The waterway marked a boundary during the colonial period in the 17th century between the properties that shaped early settlement in the region. Over time, as the area developed, the channel became primarily a drainage system for the growing metropolitan area.

The park built over the flood-prone channel between 2013 and 2017 is named after Víctor Jara, the singer-songwriter killed after the 1973 coup. It serves residents of Macul, San Joaquín, San Miguel, Pedro Aguirre Cerda and Santiago, and doubles as flood-control infrastructure for the brook's overflow.

The location is accessible and open throughout the day for walking and enjoying the green spaces along the waterway. During heavy rain, water levels can rise, so it is wise to check conditions before visiting the banks or lower areas.

The flood-control park built between 2013 and 2017 is named after Víctor Jara and doubles as a basin: it holds overflow from the Zanjón de la Aguada to protect Macul, San Joaquín, San Miguel, Pedro Aguirre Cerda and Santiago.
