Haddon Hall Upper Dam dam
Haddon Hall Upper Dam
Haddon Hall Upper Dam, located in Wake County, North Carolina, is a privately owned structure primarily used for fish and wildlife pond management. The dam, classified as an Earth type with a hydraulic height of 14 feet and a structural height of 19 feet, holds a normal storage capacity of 8 acre-feet and covers an area of 1.1 acres. Despite its relatively small size, the dam is considered to have a high hazard potential and a poor condition assessment, as last inspected in December 2019.
The dam is regulated and permitted by the North Carolina Department of Environmental Quality's Dam Safety Program, indicating that it undergoes regular inspections and enforcement to ensure compliance with safety standards. With a history of poor condition and high hazard potential, it is crucial for the owners and regulators to prioritize maintenance and risk management measures to prevent any potential hazards or emergencies. While the dam serves important purposes for fish and wildlife conservation and recreation, its structural integrity and safety should remain a top priority for all stakeholders involved in its management and oversight.
Given its location in a populated area and its potential impact in the event of a failure, Haddon Hall Upper Dam serves as a reminder of the importance of proper maintenance and monitoring of these structures. It is essential for dam owners, regulatory agencies, and the community to work together to ensure the safety and longevity of the dam, as well as the protection of the surrounding environment and residents. As climate change continues to pose challenges to water resources and infrastructure, proactive measures and risk assessments are vital in safeguarding against potential disasters related to dams and other water management structures.

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 Haddon Hall Upper Dam
Where does the data for Haddon Hall Upper 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.
