Petaluma Reservoir is a small, man-made lake located about 5 miles (8 km) northeast of Petaluma in Sonoma County, California, United States. Also known as Lawler Reservoir, its waters are impounded by Lawler Dam, a rock fill dam 40 feet (12 m) high and 1,150 feet (350 m) long that was built in 1910. The City of Petaluma owns the reservoir.

In 1992, the State of California declared the reservoir unsafe in the event of an earthquake. Rather than perform a seismic retrofit of the dam, the City decided to stop using it for water supply.
