Summary
Designed by USDA NRCS, this earth dam with a height of 28 feet serves the primary purpose of flood risk reduction in the region. With a storage capacity of 585 acre-feet, the dam is regulated by the Mississippi Department of Environmental Quality and is considered to have a low hazard potential.
The dam, part of the Chiwapa Creek watershed, has a drainage area of 1.51 square miles and features an uncontrolled spillway. Despite being uncontrolled, the dam is inspected, regulated, and enforced by the state authorities to ensure its structural integrity and safety. With a moderate risk assessment rating of 3, the Chiwapa Watershed Structure 24 Dam plays a vital role in managing flood risks in the area and protecting the local community from potential inundation events. For water resource and climate enthusiasts, this dam serves as a significant infrastructure contributing to the overall water management efforts in Pontotoc County, 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.
