Summary

1, located in Clements, California, along the Mokelumne River, is a vital structure with a primary purpose of water supply. This earth-type dam stands at a height of 90 feet and has a length of 6000 feet, providing a storage capacity of 417,000 acre-feet. With a surface area of 7600 acres, the dam plays a crucial role in flood risk reduction, hydroelectric power generation, recreation, and supporting fish and wildlife habitat in the region.

Managed by a public utility, Camanche Dike No. 1 is regulated by the California Department of Water Resources (DWR) under the Safety of Dams program, ensuring regular inspections and enforcement of safety measures. The Federal Energy Regulatory Commission (FERC) also plays a role in the regulatory oversight of the dam's operations. Despite its high hazard potential, the condition assessment of the dam is currently not available, highlighting the need for continued risk management and monitoring to ensure the safety and reliability of the structure.

With its strategic location and critical role in water resource management, Camanche Dike No. 1 serves as a significant infrastructure for the surrounding communities and ecosystems. As climate change impacts water resources, the dam's importance in providing water supply and protecting against floods becomes increasingly crucial. Understanding the complexities of managing such structures is essential for water resource and climate enthusiasts to advocate for sustainable water management practices in the face of changing 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.
