Summary

Constructed in 1926, this earth dam stands at a height of 107 feet and has a storage capacity of 10,700 acre-feet, serving the surrounding area by controlling the flow of Gordon Valley Creek. With a surface area of 377 acres and a drainage area of 17 square miles, Lake Curry plays a crucial role in managing water resources in the region.

Despite being classified as having a high hazard potential, Lake Curry is currently in fair condition as per its last assessment in 2017. Regular inspections, conducted annually, ensure that the dam meets safety standards and can effectively manage flood risks in the area. The dam's emergency action plan, though last revised in 2015, is designed to guide responses in case of any unforeseen events, providing a framework for emergency preparedness. With its proximity to the San Francisco District and the oversight of the Department of Water Resources, Lake Curry remains a key component of water management infrastructure in California.

Enthusiasts interested in water resources and climate change will find Lake Curry to be a fascinating case study of how local government entities work to balance flood risk reduction and water supply needs. The dam's strategic location, coupled with its historical significance and ongoing maintenance efforts, highlight the importance of effective water resource management in the face of increasing climate challenges. By understanding the intricacies of Lake Curry and similar structures, enthusiasts can gain valuable insights into the intersection of infrastructure, environmental conservation, and sustainable water practices.

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.
