About this dam

B. Everett Jordan Dam

B. Everett Jordan Dam, located in North Carolina along the Haw River, is a federal Earth-type dam completed in 1974 by the US Army Corps of Engineers. With a height of 114 feet and a length of 1330 feet, the dam serves various purposes including flood risk reduction, fish and wildlife pond, hydroelectric power generation, recreation, and water supply. The dam has a high hazard potential and a moderate risk assessment rating, with a storage capacity of 1,646,560 acre-feet and a maximum discharge of 259,000 cubic feet per second.

USACE actively manages the dam-related flood risks by monitoring its condition, prioritizing risk-reducing activities, and collaborating with local emergency managers and the public to raise awareness and preparedness for potential emergencies. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality. The dam has uncontrolled spillways, and the USACE continually updates the emergency action plan and works towards enhancing risk management measures to mitigate the impact of severe weather events and potential flooding. Water resource and climate enthusiasts can appreciate the critical role of B. Everett Jordan Dam in safeguarding the surrounding communities and environment from flood risks and ensuring sustainable water resource management.

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.

FAQ

About B. Everett Jordan Dam

Where does the data for B. Everett Jordan 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.
