Summary
Built in 1936, this earth dam stands at a height of 12 feet and stretches 270 feet in length, providing a storage capacity of 125 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2015 reported poor conditions, highlighting the need for maintenance and repairs to ensure its long-term stability.
The dam, primarily owned by the local government, is regulated by the Indiana Department of Natural Resources and undergoes regular inspections to ensure public safety. With a moderate risk assessment rating of 3, there is a need for implementing risk management measures to mitigate any potential hazards. The dam's primary purpose for recreation attracts water resource and climate enthusiasts to enjoy the surrounding park area, although its poor condition calls for attention to ensure the safety and longevity of this essential infrastructure.
As a focal point for outdoor activities in Greensburg, the City Park Dam presents an opportunity for collaboration between local authorities, regulatory agencies, and the community to address its maintenance needs. By prioritizing improvements and implementing risk management strategies, this dam can continue to provide both recreational enjoyment and essential water resource management for years to come.

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.
