Summary
Moore Park Dam, located in Forest Homes, Illinois, is a vital structure regulated by the Illinois Department of Natural Resources (IDNR) to ensure its safety and functionality. Completed in 1988, this earth dam serves primarily for recreation purposes along the Trib West Fork Wood River. With a height of 27 feet and a length of 460 feet, the dam provides a normal storage capacity of 52 acre-feet and a maximum discharge of 3035 cubic feet per second.
Managed by the local government, the Gordon F. Moore Park Dam has a significant hazard potential but is considered to have a moderate risk level. The dam features an uncontrolled spillway with a width of 54 feet and outlet gates for water release. Although the condition assessment is not available, the dam undergoes inspections every three years to ensure its safety and structural integrity.
Climate and water resource enthusiasts will appreciate the strategic importance of the Gordon F. Moore Park Dam in managing water flow and storage in the region. With its impressive storage capacity and recreational significance, this dam plays a key role in the local ecosystem and provides valuable insights into dam management practices for sustainable water resource management in Illinois.

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.
