Second Broad W.S. Structure #13 dam
Second Broad W.S. Structure #13
Second Broad W.S. Structure #13, located in Bostic, North Carolina, along Mill Creek, is a privately-owned earth dam primarily designed for flood risk reduction. Constructed in 1990 by the USDA NRCS, this dam stands at a structural height of 39 feet with a hydraulic height of 18.4 feet. With a normal storage capacity of 172 acre-feet and a maximum storage of 1269 acre-feet, it serves a drainage area of 1895 acres, covering a surface area of 21.5 acres. Despite its high hazard potential, the dam's condition assessment in 2019 rated it as fair, with a moderate risk level.
This dam is regulated by the NCDEQ Dam Safety Program, ensuring that it undergoes regular inspections and enforcement to maintain its integrity. While it currently has uncontrolled spillways and outlet gates, the structure has not been modified since its completion. The associated risk assessment categorizes it as moderate, emphasizing the importance of ongoing risk management measures to mitigate any potential hazards. Overall, Second Broad W.S. Structure #13 serves as a vital component in the flood risk reduction efforts within the region, highlighting the intersection of water resource management and climate resilience.
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.
Plan around the weather

About Second Broad W.S. Structure #13
Where does the data for Second Broad W.S. Structure #13 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.
