Summary
Completed in 1900, this Earth type dam stands at 22 feet high and has a storage capacity of 400 acre-feet, serving primarily for irrigation and water supply purposes. With a surface area of 76 acres and a drainage area of 12.1 square miles, Madeline plays a crucial role in managing water resources in the region.
Maintained and regulated by the California Department of Water Resources (DWR), Madeline has a low hazard potential and is considered to be in satisfactory condition as of the last assessment in September 2017. The dam has a history of meeting state inspection, permitting, and enforcement requirements, ensuring its operational safety and efficiency. Despite its age, Madeline continues to be a vital infrastructure for water management in the area, providing essential support for agricultural and domestic water needs.
Managed under the oversight of the San Francisco District of the US Army Corps of Engineers, Madeline exemplifies the importance of proper dam maintenance and regulation in safeguarding water resources and mitigating potential risks. With its strategic location and functional design, this historic dam stands as a testament to the enduring significance of water infrastructure in sustaining communities and ecosystems in the face of changing climate patterns and evolving water demands.

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.
