Summary

With a height of 28 feet and a storage capacity of 310 acre-feet, this dam on the Tr Sfk Yuba River boasts a surface area of 18 acres and serves as a vital resource for the region. The dam's hazard potential is classified as high, but its condition assessment remains satisfactory, ensuring its continued functionality and safety.

Managed by the California Department of Water Resources and regulated by the Safety of Dams division, Lake Angela plays a crucial role in water management in Nevada and California counties. Its proximity to the river and strategic location make it an essential component of the local water supply infrastructure. The dam's last inspection in October 2020 deemed it structurally sound, with a comprehensive emergency action plan in place to mitigate any potential risks.

Enthusiasts of water resources and climate will appreciate the historical significance and engineering prowess behind Lake Angela. As a key public utility structure in the area, it not only provides essential water supply but also showcases the importance of effective dam regulation and maintenance. With its impressive design, strategic location, and satisfactory condition, Lake Angela stands as a testament to responsible water resource management in the face of changing climate patterns.

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.
