Eden Creek Watershed Structure Y-37-03 Dam Reservoir Report
Last Updated: March 3, 2026
Located in Yazoo City, Mississippi, the Eden Creek Watershed Structure Y-37-03 Dam, also known as Tinnin's Lake, was completed in 1973 by the USDA NRCS.
Summary
This earth dam, with a height of 39 feet and a storage capacity of 263 acre-feet, serves primarily for flood risk reduction along the TR- EDEN CREEK. The dam is state-regulated and maintained by the Mississippi Department of Environmental Quality, with a low hazard potential and a moderate risk rating.
The dam features an uncontrolled spillway and outlet gates, with a buttress core type and soil foundation. While the condition of the dam is currently not rated, it undergoes regular state inspections and enforcement to ensure its structural integrity and functionality. With its critical role in mitigating flood risks in the region, the Eden Creek Watershed Structure Y-37-03 Dam stands as a vital infrastructure managed by the local government for the protection of surrounding communities and water resources.
For water resource and climate enthusiasts, the Eden Creek Watershed Structure Y-37-03 Dam offers a fascinating case study in flood risk reduction and dam management practices. From its construction by the USDA NRCS to its state regulation and inspection protocols, this dam exemplifies the intersection of engineering, environmental stewardship, and public safety. As climate change continues to impact water systems, understanding the role of structures like the Eden Creek Dam becomes increasingly relevant for ensuring sustainable water resource management in the face of evolving climatic challenges.

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.
