Summary

Managed by the Tennessee Safe Dams Program, the dam on Horn Lake Creek was completed in 1951 and stands at a hydraulic height of 12.8 feet and a structural height of 17 feet. With a storage capacity of 931 acre-feet and a surface area of 95 acres, the lake offers ample space for outdoor activities such as boating, fishing, and picnicking.

Despite its significant hazard potential and unsatisfactory condition assessment, Coro Lake continues to attract visitors seeking a natural escape within Shelby County. The dam's spillway type is listed as uncontrolled, and the last inspection in December 2018 revealed the need for improvement. As a moderate risk site with a risk rating of 3, ongoing risk management measures are essential to ensure the safety and sustainability of this beloved water resource in the region.

While the dam lacks certain emergency preparedness protocols such as an updated EAP and inundation maps, the presence of the Tennessee Safe Dams Program as the regulatory agency indicates a commitment to enforcing state regulations and conducting regular inspections. With its tranquil waters and picturesque surroundings, Coro Lake remains a valued asset for the community, offering both recreational opportunities and a reminder of the importance of proactive dam safety measures in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
