Summary
Owned privately, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections. With a height of 29 feet and a length of 342 feet, the dam has a storage capacity of 70 acre-feet and a spillway width of 57 feet. The hazard potential of the dam is classified as low, with a moderate risk assessment rating.
Managed by the USDA NRCS, Shepherd Pond Dam is an earth dam with a buttress core type, situated on the Tributary of Ackerman Creek. Although the condition assessment is currently unavailable, the dam's emergency action plan and risk management measures are under evaluation. With a moderate risk level assigned to the dam, continuous monitoring and maintenance are essential to ensure its safety and function. Water resource and climate enthusiasts can appreciate the significance of Shepherd Pond Dam in providing recreational opportunities while also recognizing the importance of proper management and upkeep to prevent potential risks.

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.
