Summary

Built in 1966, this earth dam stands at 19 feet tall and serves a primary purpose of water supply. With a storage capacity of 90 acre-feet and a surface area of 12 acres, Lindero plays a significant role in meeting the water needs of the region.

Managed by the California Department of Water Resources (DWR) and regulated by the Safety of Dams agency, Lindero is subject to regular inspections to ensure its structural integrity. Despite being classified as having a significant hazard potential, the dam's condition was assessed as satisfactory during the last inspection in July 2018. The surrounding Lindero Creek provides a picturesque setting for recreational activities, further highlighting the dam's importance in both water supply and leisure.

While Lindero's design and construction are primarily focused on water supply, the dam also offers opportunities for recreation. Its location near the Los Angeles District and the presence of nearby Congressman Ted Lieu make it a key feature in the water management infrastructure of the area. With its storied history and ongoing regulatory oversight, Lindero stands as a vital resource for both water conservation and climate resilience efforts in Southern California.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
