Zanja Madre, Historic water system in Downtown Los Angeles, United States
The Zanja Madre is a canal system built in the 18th century to carry water from the Los Angeles River to the original pueblo, constructed with brick-lined conduits. Visitors today can see preserved sections of this water channel near the Gold Line tracks and within the Pueblo de Los Angeles Historical Monument.
The system was founded in 1781 to supply the early settlement with water and was the city's first municipal water channel at that time. A large water wheel was added in 1857 to increase capacity as the population grew.
