Summary
Constructed in 1967 by the USDA NRCS, this Earth type dam stands at a height of 26 feet and spans 800 feet in length, with a storage capacity of 652 acre-feet. Situated on the TR-CHIWAPA CREEK, this dam plays a crucial role in managing water flow and reducing flood risks in the area.
Despite its importance, Chiwapa Watershed Structure 13 Dam is currently assessed to be in poor condition, with a significant hazard potential. The dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its structural integrity. However, the last inspection date was in February 2016, raising concerns about the ongoing maintenance and management of this critical water resource infrastructure.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper upkeep of Chiwapa Watershed Structure 13 Dam to safeguard against potential risks and ensure its continued effectiveness in flood risk reduction. With its strategic location and significant impact on the surrounding Pontotoc County, Mississippi, the proper maintenance and management of this dam are crucial for the overall safety and well-being of the community.

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.
