Summary
Completed in 1980, this dam stands at 18 feet high and spans 450 feet in length, providing a storage capacity of 314 acre-feet. The primary purpose of this dam is for water supply, serving as a crucial resource for the surrounding area.
Owned by the local government and regulated by the Illinois Department of Natural Resources, the Omaha Township Civic Center Dam plays a vital role in managing the water resources in the region. This dam, situated along the Trib Bear Creek, has a spillway type of uncontrolled and features uncontrolled outlet gates. Although the condition assessment is not available, the hazard potential is deemed significant, with a moderate risk assessment score of 3.
With its strategic location and essential role in water supply, the Omaha Township Civic Center Dam serves as a key infrastructure for the community of Omaha, Illinois. As a focal point for water resource and climate enthusiasts, this dam represents a critical piece of the region's water management system, ensuring the availability of water for various purposes. Its design by CLARK, DEITZ ENGINEERS reflects a commitment to sustainable water resource management and underscores the importance of maintaining and regulating such vital infrastructure for the benefit of the local population.

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.
