Due to seasonal runoff from the mountains to the south, a very large part of Tehachapi Valley lies in a flood plain. Periodic flooding has occurred many times and was particularly devastating in 1932 and 1945.
Through cooperative efforts with State and Federal agencies over many years, the District obtained sufficient funds to build flood control facilities that now provide a high degree of protection to homes, businesses, roads and other developments in the Tehachapi Valley. Antelope Dam and Blackburn Dam are the major structures created for flood control.
Many homes in the Tehachapi Valley have been removed from the flood hazard designation, reducing flood insurance costs and enhancing property values.
