Summary
This earth dam stands at a height of 10 feet with a length of 1000 feet, providing a storage capacity of 104 acre-feet and covering a surface area of 20 acres. Despite its small size, the dam plays a crucial role in managing water resources in the area, especially for agricultural and livestock needs.
While Vergara Ranch Dam No 2-72 does not have a spillway and is not regulated by the state, it is still subject to state permitting and inspection requirements. With a high risk assessment rating of 2, the dam's condition assessment remains unrated, posing potential hazards that need to be monitored and managed. Even without a designated emergency action plan in place, the dam represents a vital component of the local water infrastructure and highlights the importance of maintaining and monitoring these structures for the safety and sustainability of surrounding communities and ecosystems.
As water resource and climate enthusiasts, understanding the significance of small dams like Vergara Ranch Dam No 2-72 in managing water supply, wildlife habitats, and emergency response is crucial. Despite its modest size and limited regulatory oversight, this dam exemplifies the critical role that such structures play in supporting local ecosystems and agricultural activities. By continuing to assess and monitor the dam's condition and implementing necessary risk management measures, stakeholders can ensure the long-term functionality and resilience of this essential water resource infrastructure.

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.
