Summary
Built in 1980, this earth-type dam stands at a height of 19 feet with a hydraulic height of 15.5 feet, providing a storage capacity of 150 acre-feet for water supply purposes. The dam spans 1550 feet in length, covering a surface area of 24 acres and draining an area of 0.5 square miles.
Managed by the California State agency, Vicini is regulated, permitted, inspected, and enforced for safety and compliance with state regulations. With a low hazard potential and a satisfactory condition assessment as of September 2017, the dam is subject to regular inspections every year to ensure its structural integrity and functionality. Despite its low risk profile, Vicini remains an essential component of the local water supply infrastructure, serving the irrigation and water supply needs of the surrounding area.
Representative Tom McClintock (R) oversees Vicini within the San Francisco District, ensuring the dam's adherence to federal guidelines and standards. As a crucial water resource in the region, Vicini's operational efficiency and safety measures play a vital role in sustaining the water supply and mitigating climate-related challenges in the area. Enthusiasts of water resources and climate management can appreciate the significance of Vicini in maintaining a reliable and sustainable water source for the community.

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.
