Summary
Completed in 1959, this earth dam stands at a height of 20 feet and has a storage capacity of 298 acre-feet, with a maximum discharge of 523 cubic feet per second. The dam spans 572 feet in length and covers a drainage area of 1.21 square miles.
Managed by the Natural Resources Conservation Service, Chilli Creek WS Str Lt-8-8 (Oaklimeter) has a low hazard potential and a moderate risk assessment rating of 3. While the condition assessment is listed as "Not Rated," the dam is regulated by the Mississippi Department of Environmental Quality, with state permitting, inspection, and enforcement in place. The spillway type is uncontrolled with a width of 60 feet, and the outlet gates are also uncontrolled. Despite its age, the dam remains functional in its flood mitigation efforts, contributing to the overall water resource management in the area.
Overall, Chilli Creek WS Str Lt-8-8 (Oaklimeter) is a vital infrastructure for flood control in the region, playing a crucial role in mitigating potential risks and protecting the surrounding community from water-related hazards. With its design focused on flood risk reduction and its ownership and maintenance overseen by federal agencies, this earth dam exemplifies the collaborative efforts needed to ensure the sustainable management of water resources in the face of changing climate conditions. Its strategic location and operational integrity make it a key component in the water resource infrastructure of Mississippi, safeguarding against potential flooding events and contributing to the overall resilience of the region.

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.
