Summary

Completed in 1979, this offstream Earth dam serves the primary purpose of water supply, with additional functions including flood risk reduction and irrigation. With a dam height of 30 feet and a storage capacity of 2100 acre-feet, Meadow Lane plays a crucial role in managing water resources in the region.

Managed by the local government and regulated by the California Department of Water Resources (DWR), Meadow Lane has a significant hazard potential but is currently rated as being in satisfactory condition. Regular inspections ensure its structural integrity, with the last assessment conducted in September 2017. The dam is equipped with emergency action preparedness plans to mitigate risks and ensure the safety of surrounding communities in case of any unforeseen events.

With its strategic location in Sonoma County and its contribution to water supply and flood control, Meadow Lane is a key asset for water resource management in the region. Climate and water resource enthusiasts can appreciate the role this dam plays in ensuring water security and mitigating flood risks, highlighting the importance of maintaining and monitoring such critical infrastructure for a sustainable future.

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.
