Summary

Kerr Dam - Saddle Dike 2, located in Boydton, Virginia, is a federal-owned earth dam completed in 1952 with a primary purpose of flood risk reduction. With a height of 15 feet and a length of 910 feet, this dam plays a crucial role in managing water levels along the Roanoke River. The dam has a surface area of 48,900 acres and a drainage area of 7,800 acres, highlighting its significance in flood control efforts.

Managed by the US Army Corps of Engineers, John H. Kerr Dam - Saddle Dike 2 has a high hazard potential and a risk assessment rating of 2. The dam's risk management measures include regular monitoring of its condition, prioritizing activities to reduce risks, and collaborating with emergency managers and the public to enhance preparedness for any dam-related emergencies. The USACE continually updates the emergency action plan for the dam and performs maintenance and repairs as necessary to ensure its proper functioning.

Despite its critical role in flood risk reduction, the dam does not eliminate all flooding risks, especially during severe weather events that can overwhelm the system. The USACE works diligently to address all types of flood risks associated with the dam and communicates with local emergency managers to develop evacuation plans and raise awareness in the event of a dam-related emergency. More detailed information specific to John H. Kerr Dam - Saddle Dike 2 will be provided in the future, reflecting ongoing efforts to manage and mitigate risks effectively.

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.
