Summary
Genevieve, Missouri. Completed in 1992, this rockfill dam stands at a height of 81 feet and has a length of 2700 feet, providing a storage capacity of 850 acre-feet. The dam serves a vital purpose in regulating water flow and providing flood control in the area, with a drainage area of 90 square miles.
Managed by the DAM AND RESERVOIR SAFETY PROG in Missouri, the dam has been inspected regularly to ensure its structural integrity and safety standards. With a high hazard potential due to its size and location, the dam has been rated as in satisfactory condition as of the last assessment in 2007. Emergency action plans are in place to address any potential risks, and the dam's moderate risk level is continuously monitored and managed to ensure the safety of surrounding communities and water resources.
Mississippi Lime Upper Dam is a key component in water resource management in the region, providing essential flood control and water storage capabilities. With its strategic location and design, the dam plays a crucial role in maintaining the water supply and protecting against potential hazards, making it a vital asset for climate and water resource enthusiasts to monitor and appreciate in the ongoing effort to ensure the sustainability and resilience of our water systems.

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.
