Summary
The dam stands at 7 feet high, with a length of 240 feet, and has a storage capacity of 82 acre-feet. Despite its low hazard potential, the dam's condition is currently rated as "Not Rated," indicating a need for further assessment and maintenance.
Although Overberg Wpa #2 does not fall under state regulation or permitting, it serves an important role in water resource management in the region. With a maximum discharge of 25 cubic feet per second, the dam helps control the flow of water in the tributary and provides water storage for various purposes. However, the lack of recent inspection and assessment data raises concerns about the dam's long-term stability and effectiveness in mitigating flood risks.
As water resource and climate enthusiasts, it is imperative to monitor and prioritize the maintenance of critical infrastructure like Overberg Wpa #2 to ensure the safety and sustainability of water resources in the area. Collaborative efforts between Federal agencies, local stakeholders, and the community are essential to address any potential risks and safeguard the dam's functionality for future generations.

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.
