Summary
This earth dam, with a height of 22 feet, has a storage capacity of 247 acre-feet and covers a drainage area of 461 acres. The dam, situated on Town Creek, has a surface area of 21 acres and a normal storage capacity of 107 acre-feet.
Despite being classified as having a high hazard potential, City Lake Dam has not been rated for its condition assessment. The last inspection of the dam was conducted in April 1979, with no subsequent inspections reported. The dam's emergency action plan status, risk assessment, and risk management measures are also unknown. With its critical role in water supply and the potential risks associated with its high hazard classification, monitoring and maintenance of City Lake Dam are crucial to ensure the safety and security of the surrounding community and environment.
As a key water resource structure owned by the local government, City Lake Dam on TOWN CREEK in Cass County, Missouri, falls under the jurisdiction of the Tulsa District of the U.S. Army Corps of Engineers. With no state regulation or permitting in place, the dam's operation, inspection, and enforcement are solely managed by the local government. In the absence of recent assessments and with limited information on emergency preparedness and risk mitigation measures, the future maintenance and monitoring of City Lake Dam are essential to safeguard its integrity and protect the community from potential hazards.

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.
