N&S Mill Creek No.16 dam
N&S Mill Creek No.16
N&S Mill Creek No.16, also known as Gum Hollow, is a crucial earth dam located in Grant, West Virginia, designed by the USDA NRCS in 1984 for flood risk reduction. This dam stands at a height of 67 feet with a hydraulic height of 61 feet, serving its primary purpose effectively. With a normal storage capacity of 47 acre-feet and a drainage area of 0.09 square miles, this structure plays a vital role in managing water resources in the region.
Managed by the local government and regulated by the West Virginia Department of Environmental Protection, N&S Mill Creek No.16 has a high hazard potential but is currently deemed to be in satisfactory condition based on the last inspection in 2015. Although the dam is uncontrolled in terms of spillway and outlet gates, it meets regulatory standards and has a moderate risk rating of 3. With a strong foundation of rock and soil, this dam stands as a testament to effective flood risk reduction strategies implemented in the region.
Overall, N&S Mill Creek No.16 serves as a vital component of water resource management in the area, providing both flood risk reduction and water storage capabilities. With its strategic location and effective design, this dam stands as a symbol of successful collaboration between the USDA NRCS, local government, and regulatory agencies to ensure the safety and resilience of the surrounding communities in the face of changing climate conditions.

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 N&S Mill Creek No.16
Where does the data for N&S Mill Creek No.16 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.
