Summary

Standing at a height of 31 feet with a length of 250 feet, the dam impounds water from the tributary of the South Fork Hardware River. Despite being regulated by the Department of Conservation and Recreation in Virginia, the dam's hazard potential is currently listed as undetermined, and its condition assessment is marked as "not rated."

With a storage capacity of 55 acre-feet and a surface area of 4 acres, Wieboldts Dam plays a crucial role in providing water for irrigation while also offering recreational opportunities. Although the dam's inspection frequency is listed as 0, it is subject to state regulation, permitting, and enforcement. The dam's emergency action plan status and risk assessment information are currently marked as unknown, indicating a need for further evaluation and management measures to ensure the safety and sustainability of the structure.

As a key feature in the local water resource infrastructure, Wieboldts Dam serves as a vital resource for the surrounding community. With its location in the Baltimore District and within the jurisdiction of the state of Virginia, the dam's management and upkeep are essential for maintaining water supply reliability, flood control, and recreational enjoyment. Continued monitoring and assessment of Wieboldts Dam will be critical in safeguarding its integrity and functionality for both current and future generations of water resource and climate enthusiasts.

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.
