Summary

Built in 1966, this gravity dam stands at a height of 3 meters and has a storage capacity of 5500 acre-feet. The dam serves multiple purposes including hydroelectric power generation, irrigation, recreation, and water supply for the surrounding area.

Managed by the Federal Energy Regulatory Commission, the Faucherie Spillway Auxiliary has a spillway type of "Uncontrolled" and a high hazard potential due to its location and function. While the condition assessment is currently not available, regular inspections are conducted to ensure the safety and integrity of the structure. The dam's risk assessment is categorized as moderate, indicating a need for ongoing monitoring and management measures.

Water resource and climate enthusiasts will find the Faucherie Spillway Auxiliary an interesting case study in dam infrastructure and its role in supporting various water-related activities. With its unique design features, multiple purposes, and regulatory oversight, this gravity dam in California continues to play a crucial role in water management and conservation efforts 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.
