Nelson Dam #2 dam
Nelson Dam #2
Nelson Dam #2 is a privately owned dam located in Henry, Virginia, with a height of 20 feet and a length of 740 feet. The dam has a storage capacity of 115 acre-feet and a normal storage level of 89 acre-feet, covering a surface area of 13.2 acres. The dam is regulated by the Department of Conservation and Recreation in Virginia, with state permitting, inspection, and enforcement processes in place.
Although the hazard potential of Nelson Dam #2 is currently listed as undetermined, the condition assessment is marked as not rated. The dam has an annual inspection frequency and emergency action plan (EAP) status is not specified. The risk assessment, risk management measures, and inundation maps prepared for the dam are also not documented. Despite these gaps in information, the dam remains an important structure in the region, serving its primary purpose effectively.
Nelson Dam #2 is part of the Huntington District in Virginia and is not owned or funded by any federal agencies. The dam's primary classification is earth, with a hydraulic height matching its structural height at 20 feet. The dam's associated structures, years of modification, and outlet gates information are not available. Overall, Nelson Dam #2 presents an intriguing case for water resource and climate enthusiasts, with room for further research and evaluation to ensure its continued safety and functionality.

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 Dam #2
Where does the data for Nelson Dam #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 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.
