Summary
Genevieve, Missouri, is a privately owned structure built in 1985 with a primary purpose that remains unspecified. This earth dam stands at a height of 59 feet and stretches 1200 feet in length, offering a storage capacity of 570 acre-feet in its reservoir with a surface area of 23 acres. The dam serves a drainage area of 192 square miles and has a maximum discharge capacity of 500 cubic feet per second.
Despite its satisfactory condition assessment and regular inspections, the dam poses a high hazard potential due to its location and size. The structure is regulated and permitted by the state of Missouri, with enforcement and inspection conducted by the DAM AND RESERVOIR SAFETY PROG. In the event of an emergency, the dam lacks outlet gates and an Emergency Action Plan (EAP), highlighting the need for improved risk management measures to ensure the safety of surrounding communities and the environment. Overall, Mississippi Lime Lower Dam presents a moderate risk level and requires ongoing monitoring and maintenance to mitigate potential hazards.

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.
