Summary

Constructed in 1969 by the International Engineering Co., this public utility-owned structure plays a crucial role in providing water supply and hydroelectric power to the region. With a structural height of 54 feet and a maximum storage capacity of 90 acre-feet, Log Cabin Dam stands tall as a key player in the state's water infrastructure.

Situated on Oregon Creek in the city of Camptonville, Log Cabin Dam not only serves as a vital water supply source but also offers recreational opportunities for locals and visitors alike. The dam's spillway, with a width of 168 feet, ensures controlled water release during times of high flow, minimizing the risk of flooding downstream. Despite its high hazard potential, regular inspections by the Federal Energy Regulatory Commission and state agencies ensure that the dam remains safe and operational, meeting regulatory standards and guidelines.

As climate change continues to impact water resources and infrastructure, Log Cabin Dam serves as a critical piece in California's resilience efforts. With a moderate risk assessment rating, ongoing risk management measures are in place to address any potential vulnerabilities. The dam's emergency action plan, last revised in December 2020, reinforces the importance of preparedness and coordination in the face of unforeseen events, highlighting the dedication to safeguarding both the structure and the surrounding community in the face of evolving climate challenges.

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.
