Summary

Completed in 1989, this earth dam stands at a height of 20 feet and has a storage capacity of 310 acre-feet, primarily serving the purpose of water supply for the region. With a significant hazard potential but a satisfactory condition assessment, this dam on the Tr Windsor Creek is regulated by the California Department of Water Resources and undergoes regular inspections to ensure its safety.

Despite its modest surface area of 14 acres and drainage area of 0.02 square miles, Airport Storage Pond 2 plays a vital role in flood risk reduction, irrigation, and water supply for the surrounding community. The dam's hydraulic height of 17.5 feet and length of 3628 feet contribute to its effectiveness in managing water flow in the area. The dam is also equipped with outlet gates, though details on its spillway type and maximum discharge remain unspecified.

With Congressman Mike Thompson representing the area, Airport Storage Pond 2 stands as a necessary resource for water management in Sonoma County. As climate change continues to impact water resources, the proper regulation and maintenance of dams like Airport Storage Pond 2 are essential for ensuring the safety and sustainability of water supplies in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
