Summary

This private dam, standing at a height of 20 feet and a length of 410 feet, has a storage capacity of 109.9 acre-feet, with a normal storage level of 26.3 acre-feet. Despite its critical role in mitigating flood risks in the area, the hazard potential of Farmwell Hunt Dam remains undetermined, and its condition assessment has not been rated.

Managed by the Department of Conservation and Recreation in Virginia, Farmwell Hunt Dam is subject to state regulations, permitting, inspection, and enforcement. The dam, although not federally owned or funded, plays a crucial role in protecting the surrounding community from potential flooding events. With its location within the Baltimore District of the US Army Corps of Engineers, the dam's operational efficiency and structural integrity are closely monitored.

As water resource and climate enthusiasts, understanding the significance of Farmwell Hunt Dam in flood risk reduction efforts is paramount. Its strategic placement along the Beaverdam Run tributary highlights the importance of proactive dam management and maintenance to ensure the safety and well-being of nearby residents. Monitoring developments and updates related to Farmwell Hunt Dam can provide valuable insights into the intersection of water resource management and climate resilience in the region.

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.
