Summary
Completed in 1974, this Earth dam stands at a height of 28 feet and has a length of 160 feet. With a storage capacity of 33 acre-feet and a drainage area of 0.22 square miles, this dam plays a crucial role in water resource management in the area.
The dam, situated on TR- TURKEY CREEK, is regulated by the Illinois Department of Natural Resources and undergoes regular inspections. With a significant hazard potential and a moderate risk assessment rating, it is essential for proper risk management measures to be in place. The dam features an uncontrolled spillway with a width of 27 feet and outlet gates that are also uncontrolled. Despite its condition assessment not being available, the dam continues to be a key component in providing recreational activities and supporting local wildlife in the region.
As a part of the Kansas City District, Tompkins Pond Dam contributes to the conservation efforts in the area and highlights the importance of maintaining and managing dams for both water resource and climate enthusiasts. With its historical significance and functional purpose, this dam serves as a reminder of the critical role that infrastructure plays in sustaining ecosystems and supporting communities 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.
