Summary
With a dam height of 18 feet and a storage capacity of 80 acre-feet, this Earth-type dam on the Leaf River serves primarily for recreation purposes. The lake offers a serene environment for water resource and climate enthusiasts to enjoy various outdoor activities such as fishing, boating, and wildlife observation.
Despite its low hazard potential and moderate risk assessment, Mccormick Lake does not have a current condition assessment rating. The dam features an uncontrolled spillway and outlet gates, with no associated locks or inspection frequency specified. While the lake's emergency action plan status and risk management measures are unclear, its location in a picturesque setting and its historical significance as a man-made water resource provide ample opportunities for exploration and appreciation by enthusiasts.
For those interested in water resource management and climate resilience, Mccormick Lake offers a unique case study in recreational dam infrastructure. As a privately-owned facility with limited federal oversight, the lake presents an intriguing blend of natural beauty and human-made engineering. By delving into the details of its construction, design, and purpose, enthusiasts can gain valuable insights into the intersection of water conservation, recreational use, and environmental stewardship in the Mississippi region.

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.
