Summary
Completed in 1989, this earth-type dam stands at a height of 15.2 meters and has a storage capacity of 737 acre-feet. It covers a surface area of 87 acres and serves purposes such as flood risk reduction and irrigation in the region. Located offstream, this pond plays a crucial role in managing water flow and protecting the surrounding areas from potential inundation.
Managed by the Department of Water Resources (DWR) for the safety of dams, Detention Pond A is subject to state regulations, inspections, and enforcement to ensure its structural integrity and functionality. The dam has a significant hazard potential but has been assessed as satisfactory in condition, with the last assessment conducted in September 2017. With a regular inspection frequency of one year, the pond is monitored closely for any maintenance needs or potential risks, with emergency action preparedness and risk management measures in place to address any unforeseen events.
The location of Detention Pond A in Solano County, California, highlights its importance in the flood control infrastructure of the region. With a designated purpose of flood risk reduction, this dam serves as a crucial component in the overall water resource management strategy of the area. As climate change continues to impact precipitation patterns and water levels, the maintenance and upkeep of structures like Detention Pond A become increasingly critical in safeguarding communities and ecosystems from the threats of flooding and water crises.

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.
