Summary
The dam stands at a height of 33 feet, with a hydraulic height of 30.6 feet, and a storage capacity of 72 acre-feet. Situated on Alder and Maple Creek, the dam serves as a vital resource for the surrounding area, with a drainage area of 0.45 square miles and a surface area of 9 acres.
Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Mill Pond is subject to regular state inspection, enforcement, and permitting to ensure its safety and compliance with regulations. Despite its age, the dam has been assessed to be in fair condition with a low hazard potential, indicating a relatively low risk to the surrounding community in case of a potential failure. The last inspection in May 2020 found the dam to be in satisfactory condition, further reinforcing its importance as a reliable water source in the region.
With its historical significance dating back over a century and its continued role in providing water supply, Mill Pond stands as a testament to the enduring importance of water resource management and infrastructure. Climate and water resource enthusiasts can appreciate the careful oversight and maintenance of this dam, ensuring its continued functionality and safety for the community it serves.

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.
