Summary

This earth dam stands at a height of 29 feet and stretches 500 feet in length, with a storage capacity of 125 acre-feet. Situated on Blair Creek, the dam is regulated by the Arkansas Natural Resources Commission and undergoes regular state inspections, enforcement, and permitting processes.

Despite its low hazard potential and a condition assessment that is not rated, the Hunton Lake Dam plays a crucial role in water resource management in the area. The dam provides essential water storage for agricultural irrigation, contributing to the sustainability of the local ecosystem. With a surface area of 7 acres and a drainage area of 3 square miles, Hunton Lake Dam serves as a vital resource for water conservation and supports the surrounding community's agricultural needs.

As a key infrastructure within the Tulsa District, the Hunton Lake Dam is a significant component of the region's water management system. While it has not been modified in recent years, the dam's operational efficiency and adherence to safety guidelines are paramount. With its strategic location and capacity to store water, Hunton Lake Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
