Summary
The dam, constructed for water supply purposes, stands at a structural height of 36 feet and has a storage capacity of 2210 acre-feet. The reservoir is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring state jurisdiction, permitting, inspection, and enforcement to maintain its safety and integrity.
With a high hazard potential but deemed to be in satisfactory condition as of the last assessment in December 2020, Lake Devin serves as a crucial resource for the surrounding community. The reservoir is associated with Hachers Run and falls under the jurisdiction of the Wilmington District of the US Army Corps of Engineers. Despite not being USACE-owned, the local government maintains and operates the dam to meet water supply needs and mitigate flood risks in the region.
Enthusiasts of water resources and climate will find Lake Devin to be a fascinating subject of study, given its strategic importance in water management and its role in providing essential services to the community. As a regulated body of water with a significant storage capacity, understanding the dam's construction, operation, and maintenance is crucial for ensuring water security and safety in the region. The reservoir's location, design, and condition make it a valuable resource for researchers and policymakers interested in sustainable water resource management and climate resilience efforts.

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.
