Summary
6, located in Clements, California, along the Mokelumne River, is a critical structure owned by a public utility with a primary purpose of water supply. This earth-type dam stands at a height of 50 feet and spans a length of 1200 feet, providing a storage capacity of 417,000 acre-feet to serve various needs including flood risk reduction, recreation, and hydroelectric power generation. The dam is regulated by the California Department of Water Resources and is subject to regular inspections to ensure its safety and compliance with state regulations.
With a high hazard potential and risk assessment rating of 2, Camanche Dike No. 6 plays a crucial role in water resource management and protection in San Joaquin County. Despite the lack of available condition assessment data, the dam has an Emergency Action Plan in place, last revised in March 2021, demonstrating preparedness for potential emergencies. The Federal Energy Regulatory Commission oversees the regulatory aspects of the dam, ensuring that it meets safety guidelines and operational standards to safeguard the surrounding community and ecosystem.
As a key component of the water infrastructure in the region, Camanche Dike No. 6 contributes significantly to water supply reliability and environmental conservation efforts. Its strategic location and design make it a vital asset for managing water resources, supporting aquatic habitats, and providing recreational opportunities for the local community. Regular monitoring and maintenance of the dam are essential to mitigate risks and ensure its long-term functionality in the face of changing climate patterns and water supply demands.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
