Lake Piru (/ˈpaɪ̯ɹu/) is a reservoir located in Los Padres National Forest and Topatopa Mountains of Ventura County, California, created by the construction in 1955 of the Santa Felicia Dam on Piru Creek, which is a tributary of the Santa Clara River.
United Water Conservation District
The elevation of the reservoir is 1,043 ft (318 m), and the elevation of the dam spillway is 1,055 ft (322 m). The dam is owned and operated by the United Water Conservation District based in nearby Santa Paula, California. The district is a multi-service district providing flood control, recreation services, surface and groundwater conservation, groundwater replenishment, and wholesale water for agriculture and urban uses to the Santa Clara River Valley and Oxnard Plain. Formed on December 5, 1950, under the Water Conservation Act of 1931, it owns approximately 2,200-acre around and including the lake and dam (890 ha).
Lake Piru Recreation Area
The Lake Piru Recreation Area, along the western shore, has about 60 acres (24 ha) with various recreational facilities for camping, boating, fishing, swimming, and picnicking. The 238 campsites have water and electric hookup along with a snack bar. There are 66 boat slips with a full-service marina. The lake is situated downstream from Pyramid Lake and can be accessed from Piru Canyon Road near the town of Piru, California.
The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Lake Piru based on levels of mercury or PCBs found in fish caught from this water body.
Quagga mussels became established in Lake Piru and then downstream in the Lower Piru Creek in 2013. While this was the first discovery in Ventura County, they are an invasive species found in various rivers and lakes in the U.S. As of 2014[update], the district was exploring options using a technical panel consisting of state Fish and Wildlife staff as well as representatives from the National Marine Fisheries Service and other federal, state, and local agencies. The district has to develop plans to deal with further colonization. The Casitas Municipal Water District that manages nearby Lake Casitas suggested that the reservoir be drained. Poisoning it with a potassium solution was also considered.
Due to harsh conditions such as debris, low visibility, different currents, whirlpools, strong winds, and cold water temperatures, a number of fatalities related to drowning have occurred at Lake Piru.
- In August 1994, 27-year-old Jesus Danilo Carranza drowned in the lake while on an outing with his family, even though he was wearing a life jacket.
- In July 1997, Liborio Dominguez of Long Beach drowned in the lake while trying to rescue his daughter. Dominguez’s body was discovered several days later.
- In September 1997, 22-year-old Isidro Castillo of Newhall drowned in the lake and his body was found a day later.

Smolyansky's 9-year-old son aided in his sister's rescue and both children survived. After a week-long search, Smolyansky's body was found floating north of Diablo Cove by a group of Lake Piru rangers and Ventura County Sheriff’s Search and Rescue divers.
