Summary
Built in 1928, this buttress-type dam stands at a height of 13 feet and has a storage capacity of 260 acre-feet. With a drainage area of 1850 square miles, Reynolds Weir plays a crucial role in managing water flow and preventing potential flooding in the region.
Managed by the California Department of Water Resources and regulated by the Safety of Dams program, Reynolds Weir has a low hazard potential and is assessed to be in satisfactory condition. Despite its age, the dam has been regularly inspected and meets state permitting and enforcement requirements. The structure also has a history of efficient operation, contributing to the overall water resource management efforts in the area.
For water resource and climate enthusiasts, Reynolds Weir serves as a fascinating example of how strategic infrastructure can effectively mitigate flood risks and support irrigation activities. Its location along the Tr Kings River highlights the interconnectedness of water management systems in California, showcasing the importance of maintaining and investing in such structures to ensure the sustainability of water resources in the region.

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.
