Second Broad Watershed Structure 11-20a
Located in McDowell County, North Carolina, the Second Broad Watershed Structure 11-20a is a vital piece of infrastructure designed for flood risk reduction along the 2nd Broad River-Tr. Constructed in 1994, this earth dam stands at a structural height of 34 feet and has a hydraulic height of 22 feet, with a length of 300 feet and a total storage capacity of 33 acre-feet. The dam serves the primary purpose of flood risk reduction, providing protection to the surrounding area with a low hazard potential.
Managed by the local government and regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, this structure undergoes inspections every five years to ensure its continued safety and functionality. With a satisfactory condition assessment as of 2016, the Second Broad Watershed Structure 11-20a has proven to be effective in managing flood risk in the region. Its location in Forest City, within a drainage area of 96 square miles, highlights its importance in safeguarding the community from potential water-related disasters.
As water resource and climate enthusiasts, understanding the details of structures like the Second Broad Watershed Structure 11-20a is essential for appreciating the intricate network of infrastructure that plays a crucial role in managing water resources and mitigating the impacts of climate change. By recognizing the efforts put into designing, constructing, and maintaining such dams, we can better appreciate the intricate balance between human development and environmental stewardship in safeguarding our communities against natural disasters.
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 Watershed Structure 11-20a
Where does the data for Second Broad Watershed Structure 11-20a 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.
