Summary
The dam serves primarily for recreational purposes, offering a surface area of 7.9 acres and a storage capacity of 94 acre-feet. With a hydraulic height of 14.1 feet and a structural height of 19.9 feet, this earth-type dam stands at a total height of 20 feet and stretches 260 feet in length. Despite its fair condition assessment and high hazard potential, the dam is regularly inspected and regulated by the North Carolina Department of Environmental Quality Dam Safety Program.
Situated within Guilford County, the Northline Corporation Dam presents a potential risk to the surrounding area due to its high hazard designation. Although its condition is assessed as fair, the dam undergoes inspections every two years to ensure operational safety and compliance with regulatory standards. The dam's emergency action plan, last revised in 2007, serves as a crucial component in mitigating risks and preparing for potential incidents. While the dam does not feature outlet gates or associated structures, its importance for recreation and water resource management in the region cannot be understated.
Ensuring the safety and integrity of the Northline Corporation Dam is essential for protecting the community and environment it serves. As a key recreational resource on the North Buffalo Creek-Tr river, this earth-type dam plays a significant role in water storage and management, with a normal storage capacity of 21 acre-feet. With its strategic location and regulated status, the dam contributes to the overall water infrastructure in Guilford County while posing a potential hazard that must be carefully monitored and managed.

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.
