Baldwin Hills Reservoir
From Wikipedia, the free encyclopedia
The Baldwin Hills Reservoir was a man-made water storage basin located on a low hilltop in Baldwin Hills, Los Angeles. It was constructed between 1947 and 1951 by the Los Angeles Department of Water and Power on a small active fault line. The design consisted of four layers above the rock foundation: an asphalt lining, a gravel drain basin, compacted clay, and a final asphalt layer on the top. The fault lines were considered during planning.
[edit] Failure
On December 14, 1963, a small crack developed in the reservoir wall. The surrounding portion of the wall was quickly eroded straight through, emptying 250 million gallons of water into the surrounding neighborhood in a few hours. In the process, 277 homes were destroyed and 5 lives were lost. Frantic rescue efforts avoided a more significant loss of life. The reservoir failure was attributed to subsidence caused by over-exploitation of the nearby Inglewood Oil Field.
The reservoir is now land and now part of Kenneth Hahn State Park.
[edit] Trivia
In a strange twist of fate, the Taum Sauk Dam failed exactly 42 years after the Baldwin Hills Reservoir failure, collapsing on December 14, 2005.
