Piney Creek Watershed Structure Y-38-03 Dam Reservoir Report
Last Updated: March 2, 2026
Piney Creek Watershed Structure Y-38-03 Dam, also known as Coleman's Lake, is a vital flood risk reduction infrastructure located in Yazoo, Mississippi.
Summary
Built in 1958 by the USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 529 acre-feet. It is regulated by the Mississippi Department of Environmental Quality and is designated as a low hazard potential structure.
The primary purpose of Piney Creek Watershed Structure Y-38-03 Dam is flood risk reduction, serving to protect the surrounding area from potential water overflow during heavy rainfall events. The dam features an uncontrolled spillway and outlet gates, with a moderate risk assessment rating of 3. While it is currently in a not rated condition assessment status, the dam is inspected, permitted, and regulated by the state authorities to ensure its functionality and safety.
Located in the TR- Piney Creek stream, this dam plays a crucial role in managing water resources and mitigating flood risks in the region. With its designer being the USDA NRCS and ownership by the local government, Piney Creek Watershed Structure Y-38-03 Dam stands as a significant infrastructure for water resource and climate enthusiasts to study and appreciate its contribution to the community's resilience against natural disasters.

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.
