About this dam

Second Broad Watershed Structure 11-14

Second Broad Watershed Structure 11-14, located in McDowell County, North Carolina, is a vital asset for flood risk reduction in the region. Built in 1994, this earth dam stands at a structural height of 38 feet with a hydraulic height of 22 feet, serving to protect the area from potential flooding events. With a normal storage capacity of 15 acre-feet and a maximum storage of 137 acre-feet, this structure plays a crucial role in managing water levels and mitigating flood risks in the Second Broad River-Tr watershed.

Managed by the local government and regulated by the North Carolina Department of Environmental Quality, Division of Energy, Mineral, and Land Resources, this dam is subject to regular inspections to ensure its satisfactory condition and low hazard potential. The structure covers a surface area of 1.7 acres and serves a drainage area of 228 square miles, highlighting its significance in the overall water resource management of the region. Despite not having a spillway or associated locks, this dam remains a key component in safeguarding the community against potential flood threats.

Overall, Second Broad Watershed Structure 11-14 is an essential infrastructure designed to protect the residents of Forest City and surrounding areas from the impacts of flooding. With its efficient flood risk reduction capabilities and satisfactory condition, this earth dam stands as a reliable barrier against water-related disasters in the Second Broad River-Tr watershed. The continued oversight and maintenance of this structure ensure its effectiveness in managing water levels and promoting the safety and resilience of the local community in the face of changing climate patterns and water resource challenges.

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.

FAQ

About Second Broad Watershed Structure 11-14

Where does the data for Second Broad Watershed Structure 11-14 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 Low 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.
