John H. Kerr Dam - Saddle Dike 2 dam
John H. Kerr Dam - Saddle Dike 2
John H. 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.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About John H. Kerr Dam - Saddle Dike 2
Where does the data for John H. Kerr Dam - Saddle Dike 2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
