Summary
Built in 1967 by the USDA NRCS, this private Earth dam serves primarily as a Fish and Wildlife Pond, providing essential habitat for local wildlife and recreational opportunities for the community. With a height of 30 feet and a length of 270 feet, the dam has a storage capacity of 37 acre-feet and covers a surface area of 4 acres.
Managed by the Illinois Department of Natural Resources (IDNR), Solomon Lake INC.Dam 1 is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. Despite its age, the dam's hazard potential remains undetermined, with a moderate risk assessment score of 3. As an Uncontrolled spillway dam, Solomon Lake INC.Dam 1 has a maximum discharge capacity of 155 cubic feet per second and is equipped with outlet gates to manage water levels in the pond.
As an integral part of the local water resource infrastructure, Solomon Lake INC.Dam 1 plays a crucial role in preserving the ecosystem and providing recreational opportunities for the surrounding community. With its strategic location and purposeful design, this Earth dam continues to serve as a valuable asset for both wildlife conservation and public enjoyment in De Witt County, 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.
