Dry Canyon Reservoir, Reservoir in the Sierra Pelona Mountains, Los Angeles County, California, United States

Dry Canyon Reservoir is a drained reservoir basin in the Sierra Pelona Mountains foothills north of Santa Clarita, California. Its 72,750 ft3 lake, at about 1,514 ft above sea level, was formed by an embankment dam on Dry Canyon Creek. Water entered from San Francisquito Canyon via Tunnel 77 and left via Tunnel 78. The basin has been mostly empty since 1966.

The reservoir was built from 1910 to 1912 as part of the region's water management system, collecting water from San Francisquito Canyon and the Los Angeles Aqueduct. A 1952 earthquake damaged the dam, leading to permanent drainage in 1966, after which the site was abandoned for water storage.

The site is accessible for walkers and nature observers exploring the open landscape. The terrain is dry and open with paths to walk, though formal amenities are minimal.

Water reached the reservoir from San Francisquito Canyon power plants through Tunnel 77 and left through Tunnel 78. After the 1966 draining, Dry Canyon Creek south of the dam was funneled into a concrete wash to protect the growing Santa Clarita suburbs downstream from flooding.
