Summary
Completed in 1969, this Earth dam stands at a height of 23 feet and spans 405 feet in length, providing a storage capacity of 175 acre-feet. With a primary purpose of recreation, the lake offers opportunities for boating, fishing, and other water-based activities within a serene natural setting.
Despite its low hazard potential, Boundary Line Lake is subject to regular inspections and maintenance by the US Army to ensure its safe operation. The lake features a Tainter (radial) outlet gate and has a spillway type of None. Its risk assessment is classified as High (2), indicating the need for ongoing risk management measures. While the condition assessment is currently listed as "Not Available," the US Army continues to monitor and assess the lake's safety features and emergency preparedness.
For water resource and climate enthusiasts, Boundary Line Lake presents a fascinating case study of a man-made recreational water body nestled within the North Carolina landscape. Its design and construction by the US Army reflect a commitment to providing safe and enjoyable outdoor experiences for visitors while also maintaining a focus on risk management and emergency response protocols. As a vital part of the local ecosystem, Boundary Line Lake serves as a valuable resource for both recreation and environmental conservation efforts in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
