Summary
This earth dam, standing at a height of 43.5 feet with a hydraulic height of 41 feet, serves the primary purpose of flood risk reduction along the TR-Tupelo Bayou. With a storage capacity of 4242 acre-feet and a drainage area of 10.2 square miles, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding.
Despite its low hazard potential and moderate risk assessment, Tupelo Bayou Site 1 has not been rated for its condition assessment. The dam, with a length of 1449 feet and a surface area of 35 acres, features an uncontrolled spillway and outlet gates. While the last inspection was conducted in May 2014, the structure remains regulated and permitted by the state of Arkansas, ensuring ongoing safety and compliance with regulatory standards. With its strategic location and design, Tupelo Bayou Site 1 is a vital component in the water resource management and climate resilience efforts in the region, demonstrating the importance of proactive flood risk reduction measures in safeguarding communities and ecosystems.

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.
