Summary

Built in 1941, this earth dam with a buttress core type serves primarily for recreation, offering a serene lake environment for residents and visitors to enjoy. The dam's maximum storage capacity of 159 acre-feet and its role in regulating the flow of the tributary to Stater Creek highlight its importance in maintaining water resources in the region.

With a height of 53 feet and a length of 260 feet, City Park Lake Dam poses a high hazard potential, yet its condition assessment as satisfactory ensures its structural integrity and safety for the surrounding community. The dam is regulated, inspected, and permitted by the Dam and Reservoir Safety Program, demonstrating a commitment to maintaining its operational effectiveness. Despite a moderate risk assessment, the dam's risk management measures and emergency action plan preparations further enhance its resilience in the face of potential hazards.

As a key feature of the local landscape, City Park Lake Dam serves as both a recreational hub and a critical component of water resource management in Crawford County. Its historical significance, structural design, and regulatory oversight underscore its importance in safeguarding the community against climate-related challenges while providing a tranquil setting for outdoor activities.

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.
