Johnson Pond Dam dam
Johnson Pond Dam
Johnson Pond Dam, located in Wake County, North Carolina, serves as a vital recreational resource along Terrible Creek. Owned privately, this earth dam stands at a structural height of 14 feet, with a storage capacity of 84 acre-feet. While the dam was last inspected in 2008 and deemed to have a significant hazard potential, its condition assessment remains unrated. Despite being non-regulated by the state, the dam continues to provide a valuable recreational outlet for the surrounding community.
With its primary purpose being recreation, Johnson Pond Dam offers a serene retreat for water resource and climate enthusiasts alike. Although the dam lacks certain regulatory oversight, its role in providing outdoor leisure opportunities cannot be underestimated. As the dam continues to age without recent modifications or inspections, concerns regarding its safety and maintenance linger, highlighting the need for ongoing monitoring and potential risk management measures to ensure the dam's long-term stability.
While George Holding (R) represents the area in Congress, the future of Johnson Pond Dam remains uncertain in terms of regulatory oversight, maintenance, and emergency preparedness. As the dam stands as a significant hazard potential, it is essential for stakeholders and authorities to prioritize its safety and potential risk reduction measures. As water resource and climate enthusiasts continue to appreciate the recreational benefits offered by the dam, a collaborative effort is needed to address any potential safety concerns and ensure the continued enjoyment of this natural setting.

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 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.
