Cox Dam dam
Cox Dam
Cox Dam, nestled in Henry, Virginia, is a privately owned earth dam with a height of 30 feet and a length of 410 feet. This structure serves a critical role in water resource management, providing a storage capacity of 22 acre-feet and a normal storage of 17 acre-feet. The dam's primary purpose and associated structures are not specified, but its state-regulated status, inspection frequency of 1, and undetermined hazard potential indicate a commitment to safety and compliance.
Managed by the Department of Conservation and Recreation in Virginia, Cox Dam's condition assessment is currently marked as "Not Rated", with no specific data on its completion year or modifications. Despite lacking certain details such as spillway type and discharge capacity, the dam's strategic location and storage capabilities make it a valuable asset for water management in the region. With its private ownership and state jurisdiction, Cox Dam stands as a testament to collaborative efforts in safeguarding water resources and adapting to changing climate conditions in the area.
While Cox Dam's risk assessment and emergency preparedness status are not specified, its presence under the Wilmington District of the US Army Corps of Engineers underscores its importance in the local water infrastructure. As a part of Congressman H. Morgan Griffith's constituency, the dam plays a vital role in flood control and water supply management. With a surface area of 1.66 acres and a latitude of 36.6233, Cox Dam serves as a key player in the sustainable utilization of water resources and climate resilience efforts in Virginia.

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 Cox Dam
Where does the data for Cox Dam 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 Undetermined 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.
