Upper (Allen Creek) Dam dam
Upper (Allen Creek) Dam
Upper (Allen Creek) Dam, located in Brunswick, North Carolina, is a state-regulated structure owned by an entity not listed in the data. The dam is situated on Allen Creek and serves a primary purpose that is labeled as "Other." While specific details about the dam's height, volume, and other physical characteristics are not provided, it is noted that the dam has a high hazard potential and its condition assessment is currently labeled as "Not Rated."
The dam falls under the jurisdiction of the North Carolina Department of Environmental Quality (NCDEQ) Dam Safety Program, which oversees permitting, inspection, and enforcement activities related to the structure. The last inspection of the Upper (Allen Creek) Dam took place on January 22, 2019, and it has a designated inspection frequency of 2. Despite the lack of specific information on the dam's design and construction, its status as a state-regulated high-hazard structure underscores the importance of ongoing monitoring and maintenance to ensure public safety and the protection of water resources in the area.
Water resource and climate enthusiasts may find the Upper (Allen Creek) Dam to be a compelling case study in dam safety and regulation. The dam's location on Allen Creek, its high hazard potential, and the involvement of the NCDEQ Dam Safety Program present a unique opportunity to explore the intersection of infrastructure management, environmental protection, and emergency preparedness. As one of many dams in North Carolina subject to state oversight, the Upper (Allen Creek) Dam highlights the complex challenges of balancing water resource management with public safety in the face of changing climate conditions.

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 Upper (Allen Creek) Dam
Where does the data for Upper (Allen Creek) 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.
