Summary

Completed in 1922, this dam stands at a height of 76 feet with a hydraulic height of 67 feet, serving the primary purpose of flood risk reduction. With a storage capacity of 239 acre-feet, Live Oak plays a crucial role in water resource management in the area, particularly during times of heavy rainfall and potential flooding events.

Managed by the local government and regulated by the California Department of Water Resources, Live Oak has a high hazard potential but is currently assessed as being in satisfactory condition. The dam underwent its last inspection in October 2020, with a routine inspection frequency of once per year. With its strategic location and important role in flood risk reduction and water supply, Live Oak remains a vital asset for the community and the surrounding area, contributing to the overall resilience and sustainability of the region's water resources.

As climate change continues to impact weather patterns and increase the frequency of extreme events, the maintenance and monitoring of dams like Live Oak are essential for ensuring public safety and effective water management. With a strong history of service since the early 20th century, Live Oak stands as a testament to the importance of infrastructure in safeguarding communities against the challenges posed by a changing climate and the need for sustainable water resource management practices in the face of uncertain environmental conditions.

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.
