Summary

Completed in 1932, this structure stands at a height of 22 feet and has a hydraulic height of 20.2 feet, providing a storage capacity of 71 acre-feet. The dam is owned and regulated by the local government and is subject to regular inspections to ensure its safety and functionality.

With a primary purpose of water supply, East Glorietta plays a crucial role in providing water resources to the surrounding area. Despite its age, the dam has been assessed as being in satisfactory condition, with a high hazard potential. The dam's last inspection in October 2020 deemed it safe, with a satisfactory condition assessment dating back to September 2017. Additionally, it meets state regulations and has a designated emergency action plan in place, highlighting the commitment to ensuring the safety and security of this essential water infrastructure.

Located in Los Angeles County, East Glorietta's presence underscores the importance of maintaining and monitoring water resource infrastructure in the face of changing climate conditions. With its strategic location and critical role in water supply, this dam serves as a key component in safeguarding water resources for the community and underscores the importance of sustainable water management practices in the region.

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.
