Second Broad River Watershed #16 dam
Second Broad River Watershed #16
Located in the picturesque Second Broad River Watershed in Bostic, North Carolina, lies Dam #16, a local government-owned structure designed by the USDA NRCS to reduce flood risks along Mountain Creek. Completed in 1979, this earth dam stands at a hydraulic height of 23 feet and a structural height of 64 feet, with a length of 600 feet and a storage capacity of 854 acre-feet. Despite its fair condition assessment in 2019, Dam #16 poses a high hazard potential and is subject to regular state regulation, inspection, and enforcement to ensure public safety.
With a drainage area of 1453 acres and a maximum discharge capacity of 4000 cubic feet per second, Dam #16 serves as a crucial flood risk reduction measure for the local community. Its spillway type is uncontrolled, and it has uncontrolled outlet gates, indicating the need for vigilant monitoring and maintenance. The dam's moderate risk assessment rating highlights the importance of ongoing risk management measures to safeguard against potential emergencies and ensure the structure's continued effectiveness in protecting the surrounding area from flooding events.
In the scenic landscape of Rutherford County, Dam #16 stands as a vital infrastructure asset for water resource management and climate resilience. As a key component of the region's flood control system, this earth dam serves as a testament to the collaborative efforts between local government agencies and the USDA NRCS in safeguarding communities against natural disasters. With its storage capacity, discharge capabilities, and state-regulated oversight, Dam #16 exemplifies the intersection of water resource management, infrastructure resilience, and environmental stewardship in the Second Broad River Watershed.

About Second Broad River Watershed #16
Where does the data for Second Broad River Watershed #16 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 below 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.
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.
