Summary
Completed in 1994, this earth dam stands at a height of 32.6 feet and has a maximum storage capacity of 22 acre-feet. With a low hazard potential and a moderate risk assessment rating, Rigdon Dam plays a vital role in managing water resources in the area.
Despite being privately owned and not regulated by the state, Rigdon Dam serves an important purpose in the local community by helping to control water flow and prevent erosion. The dam's uncontrolled spillway features a width of 10 feet, allowing for a maximum discharge of 12.5 cubic feet per second. While the dam's condition assessment is currently listed as "Not Rated," its risk management measures are considered to be moderate, ensuring the safety and stability of the structure.
In the event of an emergency, it is crucial for Rigdon Dam to have an Emergency Action Plan (EAP) in place. As of now, details regarding the EAP, including its preparation, revision dates, and compliance with guidelines, are not provided in the available data. However, with its low hazard potential and moderate risk assessment, Rigdon Dam remains a key component of water resource management in the region for both water resource and climate enthusiasts to monitor and appreciate.

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.
