About this dam

B. Everett Jordan Dam - Saddle Dike 2

B. Everett Jordan Dam - Saddle Dike 2, located in Chatham, North Carolina, is a critical flood risk reduction structure owned and managed by the US Army Corps of Engineers. Completed in 1974, this earth dam stands at 17 feet high and spans 1275 feet, with a surface area of 13940 acres and a drainage area of 1690 acres along the Haw River. Despite its high hazard potential, the dam plays a crucial role in managing water levels and mitigating flood risks in the region.

The US Army Corps of Engineers employs a comprehensive risk management approach for B. Everett Jordan Dam, continuously monitoring its condition and engaging with local emergency managers and the public to raise awareness and readiness for potential dam-related emergencies. The agency regularly updates the dam's emergency action plan, conducts maintenance and repairs as needed, and collaborates closely with local stakeholders to ensure preparedness in the event of a crisis. With a focus on addressing all types of flood risk associated with the dam, USACE remains committed to safeguarding the surrounding communities and maintaining the structural integrity of the dam.

While dams like B. Everett Jordan Dam provide critical flood risk reduction benefits, they do not eliminate all risks of flooding. Severe weather events and inconsistent water inflows can pose challenges, leading to controlled water releases or potential issues at the dam. USACE's proactive risk management measures, including ongoing monitoring, stakeholder engagement, and emergency preparedness, help to enhance the resilience and safety of B. Everett Jordan Dam and ensure its effectiveness in protecting the local area from potential flood threats.

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 - Saddle Dike 2

Where does the data for B. Everett Jordan Dam - Saddle Dike 2 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.
