Thornburg Dam #1 dam
Thornburg Dam #1
Thornburg Dam #1, located in Seagrove, North Carolina, is a private earth dam primarily used for fire protection and as a small fish pond. The dam has a hydraulic height of 23.2 feet and a structural height of 27.4 feet, with a storage capacity of 85 acre-feet and a normal storage level of 37 acre-feet. It is situated on Hannahs Creek and serves the purpose of providing water for fire protection and recreational activities like fishing.
This low hazard potential dam has been deemed to be in satisfactory condition as of the last inspection in February 2016, with an inspection frequency of 5 years. The dam is regulated by the North Carolina Department of Environmental Quality (NCDEQ) Dam Safety Program, ensuring that it meets all safety standards and is regularly inspected for any potential risks. Despite its small size, Thornburg Dam #1 plays a crucial role in providing water resources for fire protection and recreational use in the area.
With a history dating back to an unknown completion year, Thornburg Dam #1 has been a reliable water resource structure in Randolph County, North Carolina. Its modest size, low hazard potential, and satisfactory condition make it a valuable asset for the local community and a key contributor to the management of water resources in the region. Enthusiasts of water resources and climate will appreciate the importance of this dam in providing essential water storage for fire protection and recreational activities.

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 Thornburg Dam #1
Where does the data for Thornburg Dam #1 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.
