Permastone Lake Dam dam
Permastone Lake Dam
Permastone Lake Dam, also known as Fantasy Lake Dam, is a private-owned structure located in Hope Mills, North Carolina. Built in 1952, this earth-type dam stands at a structural height of 14 feet and has a hydraulic height of 11 feet. The dam serves primarily for recreational purposes, with a maximum storage capacity of 156 acre-feet and a surface area of 12 acres. The dam is situated on Rockfish Creek-Os, within the Wilmington District of North Carolina.
Despite being privately owned, Permastone Lake Dam is not regulated by the state and has not undergone state permitting or enforcement. The dam's hazard potential is classified as low, and its condition assessment remains unrated as of the last inspection in 1990. With a drainage area of 480 square miles and a maximum discharge of 100 cubic feet per second, the dam poses minimal risk to surrounding communities. While the dam lacks an emergency action plan and updated inundation maps, its risk management measures and overall safety protocols are currently unspecified.
In conclusion, Permastone Lake Dam stands as a modest yet significant recreational feature in Hope Mills, North Carolina. Despite its age and limited state oversight, the dam's low hazard potential and unremarkable risk assessment suggest a minor threat to public safety. Continued monitoring and potential updates to emergency preparedness measures could further enhance the dam's resilience and ensure the safety of nearby residents and visitors.

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 Permastone Lake Dam
Where does the data for Permastone Lake 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 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.
