Summary
Built in 1952, this Earth-type dam stands at a height of 8 feet with a length of 500 feet, providing a maximum storage capacity of 52 acre-feet. Despite its low hazard potential, the dam has not been rated for its condition assessment.
Managed by the Vicksburg District of the US Army Corps of Engineers, Arnoname 50 offers a surface area of 11.4 acres for recreational activities and serves as a popular spot for water resource and climate enthusiasts. While the dam has not been modified in recent years and does not have a spillway, it is considered a safe structure for public use. With its serene location in Laran-Louisiana and scenic views, Arnoname 50 attracts visitors looking to enjoy the outdoors.
Overall, Arnoname 50 provides a valuable recreational resource for the community and stands as a testament to the importance of proper dam management and maintenance. Its historical significance and contribution to the area's water ecosystem make it a noteworthy site for those interested in the intersection of water resources and climate preservation.

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.
