Nelson County Dam #7 dam
Nelson County Dam #7
Nelson County Dam #7, located in Nelson, Virginia, is a state-regulated dam under the jurisdiction of the Department of Conservation and Recreation. With a height of 29 feet and a length of 270 feet, this dam provides a storage capacity of 64.03 acre-feet for water resource management in the area. The dam's primary purpose and specific design details are not listed, but its structural integrity and hazard potential are currently classified as undetermined.
Although the condition assessment of Nelson County Dam #7 is marked as "Not Rated," regular inspections are conducted with a frequency of once per year to ensure its safety and functionality. The dam's Emergency Action Plan (EAP) status, risk assessment, and management measures are also listed as not determined, suggesting a need for further evaluation and planning in case of emergencies or potential risks. The dam is not under the ownership or funding of federal agencies, highlighting the local and state-level responsibility for its maintenance and operation.
Overall, Nelson County Dam #7 presents an intriguing case study for water resource and climate enthusiasts, showcasing the complexities of dam regulation, assessment, and management at the state level. As climate change impacts water resources and infrastructure, understanding the safety and functionality of dams like this one is crucial for ensuring the resilience and sustainability of our water systems. Further research and monitoring of Nelson County Dam #7 could provide valuable insights into the intersection of water resource management, climate resilience, and infrastructure maintenance in the region.
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 Nelson County Dam #7
Where does the data for Nelson County Dam #7 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.
