Hillsborough Water Supply Dam dam
Hillsborough Water Supply Dam
The Hillsborough Water Supply Dam, also known as the West Fork Eno Reservoir Dam, is a vital water supply infrastructure located in Orange County, North Carolina. Completed in 2000, this earth dam stands at a structural height of 64.8 feet and has a hydraulic height of 42.8 feet, impounding the waters of the West Fork Eno River to create a reservoir with a normal storage capacity of 7,032 acre-feet. With a drainage area of 6,046 acres and a surface area of 271.5 acres, the dam plays a crucial role in providing water for the residents of Hillsborough and surrounding areas.
Managed by the local government, the Hillsborough Water Supply Dam is regulated by the North Carolina Dam Safety Program, ensuring its safe operation and maintenance. The dam has a high hazard potential, but its condition is assessed as satisfactory, with regular inspections conducted to ensure its safety. In case of emergencies, there are protocols in place, although details regarding the Emergency Action Plan (EAP) and risk assessment are not specified in the available data. Situated within the Wilmington District of the US Army Corps of Engineers, this dam serves as a key component in the water supply infrastructure of the region, highlighting its importance for water resource and climate enthusiasts.
Overall, the Hillsborough Water Supply Dam stands as a critical piece of infrastructure in Orange County, North Carolina, providing essential water supply services to the community. As climate change continues to impact water resources, the proper management and maintenance of dams like this one are crucial for ensuring water security and resilience in the face of evolving environmental challenges. With its significant storage capacity and strategic location on the West Fork Eno River, this dam plays a vital role in supporting the water needs of Hillsborough and surrounding areas, underscoring the importance of sustainable water resource management in the region.

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 Hillsborough Water Supply Dam
Where does the data for Hillsborough Water Supply 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.
