Summary
This earth dam, with a height of 20 feet, primarily serves the purpose of recreation, offering a storage capacity of 974 acre-feet and a surface area of 91 acres. Despite being categorized with a low hazard potential, the dam's condition assessment is currently not rated, highlighting the need for further evaluation and maintenance.
Managed by the Rock Island District of the US Army Corps of Engineers, Green City Dam-Sect 16 stands as a vital component for water resource management in the area, providing recreational opportunities for the community while enhancing the natural ecosystem. With a drainage area of 920 acres and a normal storage capacity of 606 acre-feet, the dam contributes to flood control and water supply reliability for local residents. However, the lack of recent inspection data and condition assessment raises concerns about the long-term sustainability and safety of the structure.
As climate change continues to impact water resources and infrastructure resilience, the importance of monitoring and maintaining dams like Green City Dam-Sect 16 becomes increasingly crucial. With the potential for extreme weather events and changing hydrological patterns, ensuring the structural integrity and functionality of such facilities is essential for mitigating risks and safeguarding the surrounding environment. Collaborative efforts between local authorities, regulatory agencies, and the community are essential to address any potential vulnerabilities and enhance the overall resilience of this important water resource asset.

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.
