Second Broad River W.S. #10-A dam
Second Broad River W.S. #10-A
Located in McDowell County, North Carolina, the Second Broad River W.S. #10-A dam serves as a vital flood risk reduction infrastructure along the Shoal Creek. Constructed in 1984, this earth dam stands at a structural height of 48.5 feet and a hydraulic height of 22.5 feet, with a storage capacity of 534 acre-feet. The dam plays a crucial role in protecting the surrounding area from potential flooding, showcasing the importance of water resource management in the region.
Managed by the local government and regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, the Second Broad River W.S. #10-A dam is subject to regular inspections to ensure its structural integrity. Classified as a significant hazard potential structure with a satisfactory condition assessment, the dam is equipped with uncontrolled spillways and outlet gates. Despite its moderate risk level, the dam's risk management measures and emergency action plans are crucial components in safeguarding the community in case of any unforeseen events.
With its strategic location in Bostic, North Carolina, the Second Broad River W.S. #10-A dam not only serves as a flood risk reduction mechanism but also highlights the collaboration between local and state agencies in ensuring water resource sustainability. As climate change continues to impact the region, the significance of such infrastructure in mitigating potential risks and protecting the environment becomes increasingly evident, making it a critical site for water resource and climate enthusiasts to monitor and study.
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 Second Broad River W.S. #10-A
Where does the data for Second Broad River W.S. #10-A 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 Significant 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.
