2nd Broad River W.S. Structure #11-16(Brevard) dam
2nd Broad River W.S. Structure #11-16(Brevard)
The 2nd Broad River Water Supply Structure #11-16 in Brevard, also known as the Brevard Dam, is a vital part of flood risk reduction efforts in McDowell, North Carolina. Constructed in 1994 by USDA NRCS, this Earth-type dam stands at a structural height of 41.9 feet and has a hydraulic height of 21.2 feet. With a normal storage capacity of 8 acre-feet and a maximum storage of 48.1 acre-feet, this dam plays a crucial role in managing water resources in the region.
Situated on Scrub Grass Branch (Nw Fk) in Union Mills, North Carolina, this dam covers a drainage area of 238 square miles and has a surface area of 1.5 acres. Despite its high hazard potential, the dam is in satisfactory condition, as confirmed by the last inspection in April 2018. The dam does not have controlled spillways or outlet gates, emphasizing the importance of its design and construction to ensure effective flood risk reduction.
With the state regulatory agency overseeing its permitting, inspection, and enforcement, this dam exemplifies the collaborative efforts between local government and state agencies in ensuring the safety and functionality of water infrastructure. Water resource and climate enthusiasts will appreciate the strategic location and design of the 2nd Broad River Water Supply Structure #11-16, as it continues to serve its primary purpose of flood risk reduction while maintaining a moderate risk assessment rating.
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 2nd Broad River W.S. Structure #11-16(Brevard)
Where does the data for 2nd Broad River W.S. Structure #11-16(Brevard) 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.
