About this dam

Ballantyne Lower Dam

Ballantyne Lower Dam, also known as Ballantyne 2, is a private dam located in Pineville, North Carolina. Built in 1997, this earth dam stands at a hydraulic height of 28.5 feet and a structural height of 33.5 feet, with a total length of 290 feet. The dam serves primarily for flood risk reduction, with a storage capacity of 19 acre-feet and a drainage area of 61.5 square miles.

Despite its low hazard potential and fair condition assessment, Ballantyne Lower Dam plays a crucial role in mitigating flood risks in the area. Situated along the McAlpine Creek, this dam not only serves its primary purpose but also offers recreational opportunities for water resource and climate enthusiasts. With a surface area of 1.3 acres and a normal storage capacity of 11.4 acre-feet, this dam contributes to the overall water management efforts in Mecklenburg County.

Managed by a private entity, Ballantyne Lower Dam has undergone regular inspections to ensure its structural integrity and safety. The last inspection, conducted in October 2018, deemed the dam to be in fair condition. As a key component of the flood risk reduction infrastructure, this dam stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions.

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 Ballantyne Lower Dam

Where does the data for Ballantyne Lower 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 Low 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
