Summary
Managed by the Illinois Department of Natural Resources (IDNR), this earth-type dam serves primarily as a Fish and Wildlife Pond along the Sangamon River. With a dam height of 10 feet and a length of 10,957 feet, the reservoir has a storage capacity of 522 acre-feet and covers a surface area of 174 acres within a drainage area of 0.27 square miles.
Constructed by HDR-CWI Inc., the dam features a stone core and soil foundation, with an uncontrolled spillway width of 350 feet. Despite its low hazard potential, the structure has a moderate risk assessment rating. While the last inspection occurred in 2014, the dam is subject to regular state regulation, permitting, inspection, and enforcement to ensure its safety and integrity. The surrounding area offers a haven for wildlife and is popular among water resource and climate enthusiasts for its ecological significance and scenic beauty.
As a vital component of the local ecosystem, Barkhausen Refuge Dam plays a crucial role in preserving biodiversity and providing habitats for various species. Its strategic location and purpose contribute to the conservation efforts in the region, making it a key site for both environmental protection and recreational activities. With its unique characteristics and significance, this dam serves as a noteworthy example of sustainable water resource management and stewardship in Illinois.

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.
