Summary

2 is a crucial earth dam located in Lake Hughes, California, designed primarily for flood risk reduction. Completed in 1982, this dam stands at a height of 24 feet with a hydraulic height of 19 feet, spanning a length of 4437 feet and offering a storage capacity of 493 acre-feet. Situated on the Tr Antelope Vy Cr river or stream, this dam falls under the jurisdiction of the California Department of Water Resources and is regulated by the Safety of Dams agency.

Despite its low hazard potential, Fairmont No. 2 undergoes regular inspections, with the most recent assessment conducted in February 2021, indicating a satisfactory condition. The dam is equipped with necessary safety measures, although specific emergency action plans and risk mitigation strategies are yet to be fully detailed. Owned and operated by the local government, this structure not only serves the purpose of flood risk reduction but also contributes to water supply management in the region. Its strategic location and design emphasize the importance of maintaining and monitoring this essential water resource infrastructure for the benefit of the community and the environment.

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.
