San Gabriel River. Power plant The dam supports two small hydroelectric plants producing a maximum of 4.95 MW and owned by the Department of Public Works. Water from the reservoir can be bypassed through a tunnel called the Azusa Conduit to another power plant downstream of Morris Dam. The power plant is located on the south side of the San Gabriel River directly below the mouth of San Gabriel Canyon. The original power plant was first built in 1898, by the San Gabriel Electric Company, and during its first few decades of operation powered electric railway lines in Los Angeles. At the time, this 2000 kilowatt (KW) plant drew water directly from the San Gabriel River. In 1917, the plant was sold to Southern California Edison, before being incorporated into the Pasadena municipal electric system. The completion of San Gabriel Dam in 1939 ensured a steadier water supply for the power plant, and in the late 1940s a new 3000 KW facility was built to replace the old one. Trivia The dam appears in the 2001 action/war film Behind Enemy Lines and is set in southern Bosnia.
