Summary
Designed by MCCLURE ENGINEERING ASSOCIATES, this earth dam stands at a height of 45 feet and has a length of 200 feet, providing a storage capacity of 30 acre-feet. With a spillway width of 42 feet and a maximum discharge of 471 cubic feet per second, the dam serves as a vital structure for water resource management in the area.
Managed by the local government and regulated by the Illinois Department of Natural Resources, the Putnam County Conservation District Dam is classified as having a significant hazard potential and a moderate risk level. Despite its uncontrolled spillway and outlet gates, the dam undergoes regular inspections every three years to ensure its structural integrity and overall safety. With its picturesque location and essential role in providing recreational opportunities, the dam serves as a valuable asset for both the community and the environment.
As a key feature within the Rock Island District, the Putnam County Conservation District Dam not only enhances the local landscape but also contributes to water conservation efforts in the region. Its construction and operation demonstrate a commitment to sustainable resource management, showcasing the intersection of water resources and climate resilience. For water resource and climate enthusiasts, this dam serves as a fascinating example of how infrastructure can support both recreational activities and environmental stewardship in a cohesive manner.

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.
