Summary
Built in 1979, this earth dam stands at a height of 10 feet and stretches over 1200 feet in length. With a storage capacity of 168 acre-feet, it provides essential water resources for the surrounding area.
Despite its modest size, Martinez Lake Dam is a crucial asset for the community, especially in times of emergency such as wildfires or droughts. The dam has not been rated for its condition, but its hazard potential is deemed as not available. With no spillway and only one outlet gate, the dam remains a key structure for water management and conservation in the region.
While the risk assessment for Martinez Lake Dam is considered high, the dam has not been assigned a Dam Safety Action Classification (DSAC) date. The lack of information on emergency action plans and risk management measures raises concerns for the dam's long-term sustainability. For water resource and climate enthusiasts, monitoring and maintaining the integrity of Martinez Lake Dam is essential to ensuring the safety and security of the surrounding community and ecosystem.

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.
