Holly Berry Mountain Dam dam
Holly Berry Mountain Dam
Holly Berry Mountain Dam, located in Jackson County, North Carolina, is a privately owned earth dam that was completed in 1965 for recreational purposes. Situated on a tributary to Green Creek, this dam stands at a structural height of 25.4 feet and has a hydraulic height of 19.4 feet. With a storage capacity of 65 acre-feet, the dam covers a surface area of 2.8 acres and serves a drainage area of 436 square miles.
Despite its fair condition assessment as of December 2016, Holly Berry Mountain Dam poses a significant hazard potential due to its age and the surrounding environmental factors. The dam is regulated and inspected by the North Carolina Dam Safety Program, ensuring that it meets state safety standards. The dam's emergency action plan (EAP) status and risk management measures are currently not specified in the available data, suggesting that further evaluation and updates may be necessary to enhance the safety and resilience of this vital water resource.
As water resource and climate enthusiasts, the unique characteristics of Holly Berry Mountain Dam make it an intriguing site for exploration and conservation efforts. Its location in the picturesque Jackson County, North Carolina, and its role in providing recreational opportunities underscore the importance of maintaining and monitoring this dam for the benefit of the local community and ecosystem. With ongoing inspections and potential risk assessments, Holly Berry Mountain Dam represents a valuable asset that requires continued attention and stewardship in the face of changing environmental conditions and evolving safety standards.

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 Holly Berry Mountain Dam
Where does the data for Holly Berry Mountain Dam 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 Significant 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.
