Summary
Completed in 1946, this earth dam stands at a height of 32 feet and has a storage capacity of 700 acre-feet. The dam is situated along Tr El Paso Creek and serves as a vital resource for the surrounding area.
Managed by the California Department of Water Resources and regulated for safety by the Safety of Dams program, Tejon Storage 1 is considered to have a low hazard potential with a satisfactory condition assessment. The dam covers a surface area of 54 acres and has a drainage area of 1.3 square miles. Despite its age, the facility has been regularly inspected and meets state regulatory standards for operation and enforcement.
With its strategic location and historical significance in water resource management, Tejon Storage 1 serves as a critical infrastructure for water supply in the region. As climate change impacts water availability, facilities like Tejon Storage 1 play a crucial role in ensuring a reliable water source for irrigation and other essential needs. By maintaining its infrastructure and adhering to state regulations, Tejon Storage 1 continues to contribute to the resilience of California's water supply system.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
