Summary
The earth-fill dam, completed in 1975, stands at 50 feet high and spans 620 feet in length, providing a maximum storage capacity of 1,174 acre-feet of water. The reservoir covers 68 acres and is fed by Willow Creek, offering opportunities for fishing, boating, and other water-based activities in the picturesque setting.
With a significant hazard potential, Lake Dunn is subject to regular state inspection, permitting, and enforcement by the Arkansas Natural Resources Commission (ANRC). While the condition assessment is not currently rated, the dam's structural height of 30 feet and hydraulic height of 15 feet are crucial factors in maintaining the safety and integrity of the reservoir. Emergency action plans and risk management measures are important considerations for ensuring the continued protection of the surrounding community and environment in the event of a hazard.
For water resource and climate enthusiasts, Lake Dunn presents an intriguing case study of a man-made reservoir embedded in the natural landscape. Its role in providing recreational opportunities while managing water resources highlights the delicate balance between human intervention and environmental stewardship. As a state-owned and operated structure, Lake Dunn serves as a vital resource for the local community and a testament to the importance of responsible water management practices in the face of changing climate conditions.

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.
