Summary

Built in 1954 by the USDA NRCS, this earth dam with a buttress core stands at a height of 20 feet and spans a length of 385 feet. Its primary purpose is for recreation, offering a serene spot for water resource and climate enthusiasts to enjoy the outdoors.

Managed by the Illinois Department of Natural Resources, SCS Pond 22 Dam has a low hazard potential and is regulated, inspected, and enforced by state authorities. The dam has a storage capacity of 134 acre-feet, with a normal storage level of 50 acre-feet. Despite its age, the dam's condition assessment is not available, but it is categorized as having a moderate risk level (3) based on risk assessments.

With its uncontrolled spillway and outlet gates, SCS Pond 22 Dam provides a safe and enjoyable recreational space for the community. While its condition assessment and emergency action plan details are not readily available, the dam continues to serve its purpose effectively, offering a peaceful retreat for those seeking to connect with nature in the heart of Henderson County, Illinois.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
