Summary
Completed in 1978, this earth dam stands at a height of 22 feet and stretches 631 feet in length, with a storage capacity of 66 acre-feet. The dam serves as a recreational area and supports a drainage area of 0.25 square miles, with a maximum discharge of 425 cubic feet per second.
Managed by the Illinois Department of Natural Resources, Perring Pond Dam 1 is classified as having a low hazard potential and a moderate risk assessment level. While its condition assessment is not currently available, regular state inspections, permitting, and enforcement ensure the safety and functionality of the structure. With its primary purpose of providing a habitat for fish and wildlife, this dam plays a crucial role in supporting the local ecosystem and enhancing recreational activities in the area.
Despite being uncontrolled, the spillway of Perring Pond Dam 1 has a width of 60 feet, allowing for the safe release of excess water. The dam also features stone core types and soil foundations, contributing to its stability and longevity. As a key component of the Rock Creek watershed, this dam serves as a vital resource for water management and conservation efforts 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.
