Summary
With a height of 47 feet and a storage capacity of 10,900 acre-feet, the dam serves multiple purposes including irrigation, tailings management, and water supply. The dam's condition is assessed as fair, with a significant hazard potential, requiring regular inspections and enforcement by the California Department of Water Resources.
Located in the city of Milton, Salt Springs Valley Dam plays a crucial role in managing water resources in the region, with a drainage area of 20.03 square miles and a surface area of 920 acres. Despite its age, the dam continues to meet state regulatory requirements for permitting, inspection, and enforcement. The dam's primary owner, a public utility, ensures that it remains in operational condition to mitigate flood risks and support the local agricultural community.
With a spillway width and other structural details not specified in the data, the dam's design and construction reflect the engineering practices of the late 19th century. As climate change impacts water resources in California, Salt Springs Valley Dam stands as a historical landmark and a critical infrastructure for flood protection and water management in the region. Enthusiasts of water resources and climate resilience can appreciate the unique role that this earth dam plays in sustaining the ecological balance and agricultural livelihoods in the Salt Springs Valley area.

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.
