Bay Area Dam Failure Inundation Maps from ABAG
|The maps were developed by dam owners to fulfill state law requirements. The maps are intended for emergency planning purposes.|
|The maps were developed using engineering hydrology principals and represent the best estimate of where the water would flow if the dam completely failed with a full reservoir. The inundation pathway is based on completely emptying the reservoir and does not include run-off from storms.|
|Many of the maps were developed in the 1970's. Should the maps have been developed more recently, different assumptions and map-making methods would have been used.|
Copies of inundation maps for individual dams may be purchased from the California Department of Water Resources, Micrographics Department. Their phone number is (916) 653-6537.
