Summary

This earth dam is primarily used for recreation purposes and boasts a height of 28 feet and a length of 7130 feet. With a maximum storage capacity of 16,400 acre-feet and a surface area of 427 acres, the dam plays a crucial role in regulating water flow and ensuring water availability for various activities.

Managed by the Vicksburg District of the US Army Corps of Engineers, Lake Calion Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam does not have a spillway, it is equipped with outlet gates to manage water levels and discharge. The surrounding area offers a picturesque setting for outdoor enthusiasts, with opportunities for boating, fishing, and other recreational activities. Lake Calion Dam stands as a testament to sustainable water management and environmental conservation efforts in the region.

As climate change continues to impact water resources globally, Lake Calion Dam serves as a reminder of the importance of responsible water management practices. With its strategic location on Tom Creek and contributions to the local ecosystem, the dam plays a crucial role in maintaining water quality and ensuring recreational opportunities for residents and visitors alike. By staying informed about the dam's condition and potential risks, water resource and climate enthusiasts can support efforts to protect and preserve this valuable asset for future generations.

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.
