Johnson Pond Dam dam
Johnson Pond Dam
Johnson Pond Dam, located in Spring Lake, North Carolina, is a privately owned earth dam on the Little River-Trib that serves primarily for recreation purposes. Standing at a hydraulic height of 12 feet and a structural height of 16 feet, this dam boasts a length of 212 feet and a storage capacity of 6.5 acre-feet. Despite not being state regulated, it is subject to regular inspections, with the last assessment taking place in February 2021, revealing a high hazard potential but an undetermined condition rating.
The dam, with a normal storage capacity of 5 acre-feet and a surface area of 1 acre, poses a potential risk in case of structural failure, highlighting the importance of ongoing monitoring and maintenance. While no emergency action plan (EAP) or specific risk management measures are currently in place, the dam's location and design suggest the need for proactive measures to ensure the safety of surrounding communities and the preservation of the Little River-Trib ecosystem. Water resource and climate enthusiasts may find Johnson Pond Dam to be an intriguing case study in the intersection of human recreation and environmental stewardship in North Carolina.
With its scenic location and vital role in providing recreational opportunities, Johnson Pond Dam stands as a testament to the delicate balance between human development and nature conservation. As water resource and climate enthusiasts delve into the nuances of this privately owned structure, they can contemplate the implications of its high hazard potential and the need for robust risk assessment and management strategies. By examining this dam's unique characteristics and potential vulnerabilities, stakeholders can work towards ensuring its long-term sustainability and the protection of both human and environmental interests in the Moore County region.

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 Johnson Pond Dam
Where does the data for Johnson Pond 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 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 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.
