About this dam

Jordan Mill Pond Dam

Jordan Mill Pond Dam, located in Flat Rock, North Carolina, stands as a historic masonry dam completed in 1870 with a primary purpose of recreation. The dam, with a hydraulic height of 17.5 feet and a structural height of 19 feet, impounds the waters of Mud Creek-Tr, creating a serene pond covering 3.5 surface acres. With a storage capacity of 30 acre-feet and a drainage area of 1916 acres, the dam provides essential water resources for the local community while offering recreational opportunities for enthusiasts.

Despite its age, Jordan Mill Pond Dam has been well maintained, with the last inspection in March 2019 revealing a satisfactory condition. However, due to its high hazard potential, regular inspections are crucial to ensure its continued safety and functionality. The dam is state-regulated by the North Carolina Dam Safety Program, with permitting, inspection, and enforcement carried out by the NCDEQ. The dam's emergency action plan is being regularly updated, reflecting a commitment to ensuring public safety in case of any unforeseen events.

As a significant part of the local landscape, Jordan Mill Pond Dam serves as a reminder of the region's rich history and importance of water resource management. Its picturesque setting and recreational offerings make it a popular destination for visitors and locals alike, highlighting the crucial intersection of water resources and climate resilience in the region. With ongoing monitoring and maintenance, this historic dam continues to play a vital role in providing both water resources and recreational opportunities for the community.

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 Jordan Mill Pond Dam

Where does the data for Jordan Mill Pond 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.

Premium feature
