Summary
The dam, with a hydraulic height of 10 feet and a structural height of 12 feet, creates a lake with a normal storage capacity of 44 acre-feet and a maximum storage of 56 acre-feet. The dam is primarily used for recreation purposes and is classified as an Earth dam.
Despite its low hazard potential, Dudley Lake Dam has not been rated for its condition assessment. The dam is not regulated by the state and does not require regular inspections or enforcement measures. The dam does not have an Emergency Action Plan (EAP) in place and has not been assessed for risk management measures. With a maximum discharge capacity of 747 cubic feet per second, the dam plays a crucial role in managing water resources in the region.
Managed by a private owner, Dudley Lake Dam is situated on Williams Branch-TR in Arkansas. With a surface area of 10 acres and a drainage area of 0.77 square miles, the dam provides both recreational opportunities and essential water storage capabilities. While the dam's condition assessment and emergency preparedness may need improvement, it remains a key feature in the local water resource infrastructure for residents and visitors to enjoy.

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.
