Summary

This earth dam has a hydraulic height of 12 feet and a structural height of 16 feet, with a length of 375 feet. The dam has a maximum storage capacity of 108 acre-feet, with a normal storage capacity of 60 acre-feet.

The dam is situated on Eastwood Bayou-TR and is under the jurisdiction of the Little Rock District of the US Army Corps of Engineers. While Arsenal Lake Dam is classified as having a low hazard potential, its condition is currently rated as "Not Rated." Furthermore, the dam does not have a state regulatory agency overseeing its operations, inspections, or enforcement. Despite this, the dam continues to provide recreational opportunities for visitors to enjoy in the surrounding area.

Overall, Arsenal Lake Dam stands as a testament to the importance of water resource management and the role of dams in providing recreational benefits to the community. With its historical significance and picturesque location, this dam is a must-visit destination for those interested in exploring the intersection of water resources and climate impact on infrastructure.

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.
