Summary
This earth dam, standing at a height of 25 feet and stretching 600 feet in length, has a storage capacity of 63 acre-feet and serves various other functions such as fire protection, stock, small fish pond, grade stabilization, and recreation. The dam sits on TR-Kelley Branch and is under the jurisdiction of the St. Louis District of the US Army Corps of Engineers.
Despite being classified as having a low hazard potential, Mckenzie Lake Dam is considered to have a moderate risk level, with a risk assessment rating of 3. The dam is uncontrolled by an uncontrolled spillway with a width of 25 feet and has a maximum discharge rate of 69 cubic feet per second. Although the dam's condition is currently not rated, it has not been subject to recent inspections or assessments. Emergency action plans and guidelines for the dam's operation and maintenance are not readily available, highlighting potential areas for improvement in risk management and preparedness.
Water resource and climate enthusiasts may find Mckenzie Lake Dam to be an interesting case study in the management and regulation of small bodies of water for multiple purposes, including conservation and recreation. The dam's location in a rural area with a moderate risk level underscores the importance of proactive monitoring and maintenance practices to ensure the safety and effectiveness of such structures in the face of changing environmental conditions and potential hazards. Further research and attention to the dam's risk management measures and emergency preparedness could provide valuable insights for enhancing the resilience of similar dams in the region.

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.
