Summary
This earth dam, standing at a height of 20 feet and a length of 900 feet, serves as a crucial structure on the TR-James River, providing storage capacity of 950 acre-feet to support the surrounding region's water needs. The dam boasts a low hazard potential and a moderate risk assessment, making it a key asset in the area's water resource management.
Managed by the state regulatory agency DANR, Pigors Dam undergoes regular inspections to ensure its structural integrity and operational efficiency. With a drainage area of 9 square miles and a maximum discharge capacity of 5700 cubic feet per second, the dam plays a vital role in flood control and water supply management in the region. With a spillway width of 60 feet and uncontrolled spillway type, the dam is equipped to handle excess water flow during times of heightened precipitation.
Not only does Pigors Dam serve as a critical infrastructure for water resource management in Brown County, but it also contributes to the overall resilience of the surrounding communities against potential flood events. With its historical significance and continued operational effectiveness, Pigors Dam remains a symbol of the intersection between human ingenuity and environmental stewardship in the face of climate challenges.

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.
