About this dam

Pharr Yarns Dam

Pharr Yarns Dam in Spencer Mountain, North Carolina, is a private recreational dam located on the South Fork Catawba River. With a hydraulic height of 8 feet and a structural height of 12 feet, this earth-type dam spans 276 feet and has a storage capacity of 12 acre-feet. Despite its relatively small size, Pharr Yarns Dam is regulated by the NCDEQ Dam Safety Program, ensuring that it meets state inspection and enforcement standards to maintain public safety.

The dam has a fair condition assessment with a high hazard potential, indicating the need for ongoing monitoring and maintenance. The last inspection in January 2021 found the dam to be in satisfactory condition, but with room for improvement. The dam's emergency action plan status and risk assessment measures are currently unclear, highlighting the importance of proactive risk management strategies for this recreational structure.

As a popular recreational spot, Pharr Yarns Dam provides opportunities for outdoor activities in a picturesque setting. However, its high hazard potential underscores the need for continued vigilance and adherence to safety protocols. With its close proximity to the South Fork Catawba River, this dam serves as both a recreational asset and a vital component of 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.

FAQ

About Pharr Yarns Dam

Where does the data for Pharr Yarns 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.
