Lake Isabella Flood Area
Updated anticipated areas to be flooded in the unlikely event should Lake Isabella Dam fail
In early 2008, the United Army Corp of Engineer completed the initial preparation of an updated map which shows the areas around metropolitan Bakersfield which would likely be flooded in the unlikely case that the Dam should fail at Lake Isabella. As part of the maps provided the County they have also included maps which show the anticipated depth and velocity of water and the anticipated time when the flows could reach the Bakersfield area if a fail of the dam occurred.
To view these documents, it is suggested you click on the appropriate link to view the pdfs of maps. These maps are based on worst case scenario of Main Dam failure with the lake full.

The County’s interactive GIS also contains the maps which were prepared in the early 1970’s by the U.S. Army Corp of Engineers that shows the areas of Kern County which could be affected should the dam fail on Lake Isabella, Jacobsen Lake in the Cummings Valley area and Berrenda Mesa Lake north of Lost Hills.
