Big Tujunga Dam, Arch dam in Los Angeles County, US.
The Big Tujunga Dam spans across Big Tujunga Canyon in the San Gabriel Mountains, reaching a height of 244 feet and a length of 830 feet.
Constructed between 1930 and 1931 by the Los Angeles County Flood Control District, the dam required an investment of 1.2 million dollars for its completion.
The name Tujunga originates from a Tongva village, while a former settlement called Muxúnga in the Fernandeño dialect existed near the current dam location.
The dam maintains a reduced water level to handle winter floods and requires regular dredging operations to remove sediment accumulation from stormwater runoff.
During the Los Angeles flood of 1938, the structure prevented substantial debris flows that could have damaged the communities of Sunland and Tujunga.
