Summary

This earth dam, standing at a height of 190 feet with a hydraulic height of 175 feet, was completed in 1934 and has a storage capacity of 36,505 acre-feet. Situated on Bouquet Creek, the dam serves the primary purpose of water supply for the region, with a surface area of 628 acres and a drainage area of 13.6 square miles.

Managed and regulated by the California Department of Water Resources (DWR) for safety compliance, Bouquet Canyon Dam has been deemed to have a high hazard potential. However, recent inspections have reported the dam's condition as satisfactory, with the last assessment conducted in August 2018. The emergency action plan (EAP) for the dam is up to date, with the last revision in January 2018, ensuring that proper guidelines are in place for any potential risks or emergencies that may arise.

With its impressive structural specifications and critical role in water resource management in Los Angeles County, Bouquet Canyon Dam stands as a significant infrastructure for climate enthusiasts and water resource professionals alike. Its historical significance, efficient design, and ongoing regulatory oversight make it a key component in ensuring water supply reliability for the region while prioritizing public safety and environmental conservation.

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.
