Summary
Completed in 1969, this earth dam stands at a height of 31 feet and has a storage capacity of 2734 acre-feet. The dam is state-regulated and permitted by the Mississippi Department of Environmental Quality, with inspections and enforcement measures in place to ensure its safety and effectiveness.
With a low hazard potential and a moderate risk assessment rating, the Chiwapa Watershed Structure 2 Dam plays a crucial role in managing flood risks in the area. The dam is equipped with an uncontrolled spillway and outlet gates for water discharge during periods of high rainfall. Despite not being currently rated for its condition, the dam continues to serve its primary purpose of flood risk reduction for the local community in Nettleton, Mississippi.
As a key structure in the Chiwapa Creek watershed, the Chiwapa Watershed Structure 2 Dam is an essential component of the region's water resource management system. With its buttress core design and soil foundation, the dam has been instrumental in protecting the area from potential flooding events. Climate and water resource enthusiasts will appreciate the strategic location and engineering behind this important infrastructure project in Mississippi.

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.
