Summary

The dam stands at a height of 20 feet with a structural height of 12 feet and a length of 71 feet, providing a storage capacity of 84 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," S-33 has not undergone recent inspection or maintenance, suggesting a need for further evaluation to ensure its continued effectiveness and safety.

Despite its age, S-33 continues to play a crucial role in managing water resources in the area, with a maximum discharge capacity of 620 cfs. However, the lack of recent inspection data and condition assessment raises concerns about the dam's current state and readiness for potential emergencies. With the dam's emergency action plan status unknown and no risk assessment or management measures in place, there is a need for increased monitoring and maintenance to mitigate any potential risks associated with its operation and structural integrity.

As a key structure in the flood risk reduction system along the North Fork New River, S-33's importance in water resource management cannot be understated. With its location in a highly populated area and the potential for significant impacts in the event of a failure, it is essential that comprehensive assessments, inspections, and emergency preparedness measures are implemented to safeguard both the dam and the surrounding community. Efforts to improve the dam's condition rating, update emergency action plans, and enhance risk management practices are crucial steps in ensuring the long-term resilience and effectiveness of S-33 in the face of evolving climate challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
