Summary
Built in 1978 by the USDA NRCS, this Earth-type dam stands at a height of 26 feet and spans 260 feet in length. With a storage capacity of 23 acre-feet, the dam serves various purposes and is regulated by the Illinois Department of Natural Resources.
The dam's primary purpose is classified as 'Other', and it is designed with a stone core and a soil foundation. The spillway type is 'Uncontrolled', with a width of 20 feet. Despite being rated as having a low hazard potential, the dam is subject to moderate risk according to a risk assessment conducted. The last inspection in 2014 revealed that the condition assessment was not available, highlighting the need for further monitoring and assessment to ensure the dam's safety and integrity.
Situated along TR-Apple Creek S in the city of Berdan, Harold Redfern Pond Dam plays a crucial role in water resource management in the area. With a drainage area of 0.07 square miles and a maximum discharge capacity of 213 cubic feet per second, the dam contributes to flood control and water supply management. As a site of interest for water resource and climate enthusiasts, this dam serves as a reminder of the importance of maintaining and monitoring critical infrastructure to ensure the safety and sustainability of our water resources in the face of changing climate conditions.

Dam Data Reference
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.
