San Buenaventura Mission Aqueduct

The San Buenaventura Mission Aqueduct was a seven-mile long, stone and mortar aqueduct built in the late 18th and/or early 19th century to transport water from the Ventura River to the Mission San Buenaventura in Ventura, California.Accounts vary greatly as to when the aqueduct was built. One account indicates it was built between 1780 and 1790 by the Chumash Indians under the direction of a Spanish priest trained in hydrology. Others place its construction in the 1790s, and yet another indicates it was built between 1805 and 1815 by stonemasons brought from Mexico.The aqueduct supplied water for the residents of Mission San Buenaventura and irrigation for the mission's pasture and agricultural lands. Water from the aqueduct helped the mission flourish.Few vestiges of it remain today. Large sections were destroyed in a Great Flood of 1862, and settlers used stones from the old aqueduct to build homes. The combined effects of floods, land cultivation, neglect and land development reduced most of the aqueduct to rubble. The only significant section that remains is located at the mouth of Canyada canyon on land that was formerly known as Rancho Cañada Larga o Verde owned by the Canet family from 1873 until at least the 1960s. This remaining section is 100 feet long and ten feet high, and is believed to have "served as a siphon, drawing water uphill through conduits." The location is at 234 Canada Larga Road near the road's interchange with the Ojai Freeway.
