Summary
Built in 1950 for flood risk reduction, this earth dam stands at 10 feet tall with a length of 700 feet, providing a storage capacity of 80 acre-feet. With a surface area of 11.4 acres and a drainage area of 0.55 square miles, Arnoname 288 plays a crucial role in managing water resources in the region.
Despite its low hazard potential and "Not Rated" condition assessment, Arnoname 288 has not undergone recent inspections or emergency preparedness evaluations. The dam's primary purpose is flood risk reduction, and it falls under the jurisdiction of the Memphis District of the US Army Corps of Engineers. With no state regulation or permitting requirements, this dam is a significant asset in mitigating flood impacts in the area. However, the lack of recent assessments and emergency preparedness plans may pose challenges in ensuring its long-term resilience and effectiveness in managing water resources in the face of changing climate conditions.
As water resource and climate enthusiasts, it is important to monitor the condition and management of dams like Arnoname 288 to ensure their continued functionality in the face of evolving environmental challenges. By advocating for regular inspections, emergency preparedness protocols, and risk assessment measures, we can work towards enhancing the resilience of critical infrastructure like Arnoname 288 in safeguarding water resources and communities from the impacts of climate change.

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.
