Summary
Completed in 2007, this earth dam serves multiple purposes including fire protection and creating a small fish pond. With a height of 29 feet and a length of 479 feet, the dam has a storage capacity of 73.8 acre-feet and covers a surface area of 5.6 acres.
Managed by the Mississippi Department of Environmental Quality, Clear Creek Lake Dam is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam's spillway, of uncontrolled type, helps manage water flow and prevent overflow during heavy rainfall events. Despite being classified with a moderate risk level, the dam's hazard potential is currently undetermined, with its condition not yet rated.
For water resource and climate enthusiasts, Clear Creek Lake Dam presents an opportunity to explore the intersection of human-made structures and environmental conservation. With its unique design and multi-purpose functionality, this dam serves as a vital component in the local ecosystem, providing essential services while also requiring careful monitoring and maintenance to mitigate potential risks and ensure its long-term sustainability.

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.
