Summary

Built in 2002, this earth dam stands at a height of 58 feet and stretches for 900 feet, providing a storage capacity of 5,108 acre-feet. With a drainage area of 2,080 acres, the dam plays a crucial role in controlling water flow and mitigating flood risks in the area.

Managed by the DAM AND RESERVOIR SAFETY PROG, the City of Cape Girardeau Dam has a high hazard potential but is in satisfactory condition as per the last assessment in 2007. The dam has a maximum discharge capacity of 3,534 cubic feet per second and a surface area of 157 acres. Despite its importance for water regulation and flood control, the dam's normal storage capacity is listed as zero, indicating potential room for optimization in water storage and management practices.

For water resource and climate enthusiasts, the City of Cape Girardeau Dam stands as a symbol of resilience and efficiency in water management. With its strategic location and design features, this earth dam serves as a critical infrastructure for safeguarding the local community against flooding events and ensuring sustainable water resource utilization in the region. As climate change continues to impact water availability and quality, the City of Cape Girardeau Dam plays a pivotal role in adapting to these challenges and enhancing the resilience of the local water supply system.

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.
