Lake Ann Dam dam
Lake Ann Dam
Lake Ann Dam, located in Still Bluff, North Carolina, is a private earth dam built in 1952 primarily for recreational purposes. Situated on Jones Creek, the dam stands at a structural height of 12 feet with a hydraulic height of 8 feet and a length of 400 feet. The dam has a storage capacity of 58 acre-feet, with normal storage levels at 48 acre-feet. Despite being privately owned, the dam is subject to state inspections to ensure its safety and compliance with regulations.
Although the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it has not been updated or inspected since February 2015. Despite this, the dam remains a popular spot for recreational activities such as fishing, boating, and picnicking. In the event of an emergency, however, the status of the dam's Emergency Action Plan (EAP) and risk assessment measures are unclear, raising potential concerns for public safety and environmental protection in the area.
With the dam's location in Pender County, North Carolina, and its association with the Wilmington District of the US Army Corps of Engineers (USACE), there may be potential for further oversight and management of the dam in the future to ensure its continued safety and functionality for both recreational and environmental purposes. Water resource and climate enthusiasts may find interest in monitoring developments related to Lake Ann Dam and its impact on the surrounding ecosystem.

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 Lake Ann Dam
Where does the data for Lake Ann 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.
