Summary

Standing at a height of 30 feet and spanning a length of 180 feet, the dam has a storage capacity of 52 acre-feet and covers a surface area of 1.4 acres. Despite its important role in mitigating flood risks, the dam's hazard potential is currently labeled as undetermined, with a condition assessment that is not rated.

Managed by the Department of Conservation and Recreation in Virginia, Brocks Mill Dam is subject to state regulations, permitting, inspection, and enforcement. While the dam's emergency action plan status and risk assessment are not specified, the structure has not been modified in recent years. The dam does not have outlet gates or associated locks, and its spillway type and width are not provided in the available data. With its critical function in flood risk reduction, the condition and safety of Brocks Mill Dam are crucial considerations for water resource and climate enthusiasts in the region.

Although the specific construction date and last inspection details are missing, the presence of regulatory oversight and state jurisdiction suggest a commitment to maintaining the integrity of Brocks Mill Dam. With its strategic location in a flood-prone area and its importance in protecting surrounding communities from potential water hazards, the need for ongoing monitoring and assessment of the dam's structural integrity remains a priority. As water resource and climate enthusiasts continue to advocate for sustainable water management practices, the significance of structures like Brocks Mill Dam in safeguarding against flooding events cannot be understated.

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.
