Summary
Standing at a height of 25 feet, the earth dam offers a storage capacity of 107 acre-feet, with a normal storage level of 61 acre-feet. The dam is situated on the TR-Loutre River and covers a surface area of 8 acres within a drainage area of 390 square miles.
Despite its low hazard potential, the condition of Polizzi Lake Dam has not been officially rated. The dam does not fall under state regulation or inspection, as it is privately owned and not under federal jurisdiction. With a focus on recreation, the dam's primary purpose is to provide a scenic and tranquil spot for activities such as fishing, boating, and picnicking. While the dam does not have a spillway or outlet gates, its design as a buttress earth dam ensures stability and safety for visitors.
In terms of emergency preparedness, details such as an Emergency Action Plan (EAP) and risk assessment have not been updated or documented. Despite the lack of official assessments, the dam's low hazard potential suggests minimal risk to surrounding areas. Polizzi Lake Dam remains a hidden gem for water resource and climate enthusiasts seeking a peaceful retreat in the heart of Missouri's natural beauty.

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.
