The Baldwin Hills Reservoir was constructed in 1951 to provide water to the south and southwest portions of the city of Los Angeles, California.

Who designed the Baldwin Hills Dam?
The Baldwin Hills dam designer, engineer Ralph Proctor, had also worked as an assistant civil engineer for the Los Angeles Department of Water and Power on the failed St. Francis Dam, and had subsequently devised new methods of producing compacted earth fill in building its replacement.
What caused the Baldwin Hills and Teton failures?
In 2001, a new angle on failure analysis was introduced by Mahunthan and Schofield, who concluded that overcompaction of the dam fill and lining was a significant aggravating factor in both the Baldwin Hills and Teton failures.
