Summary
Pond Dam 1, located in Macoupin County, Illinois, was completed in 1960 and serves as a crucial water resource in the area. This private earth dam, designed by USDA NRCS, stands at a height of 25 feet and stretches 500 feet in length, with a storage capacity of 86 acre-feet. The dam is situated on TR- Coops Creek SW and is regulated by the Illinois Department of Natural Resources.
With a spillway width of 40 feet and a maximum discharge of 353 cubic feet per second, Kahl Bros. Pond Dam 1 plays a vital role in managing water flow and preventing potential flooding in the region. While its hazard potential is classified as undetermined, the dam has a moderate risk assessment rating. The dam's condition assessment is currently unavailable, but it undergoes regular state inspections, with the last one conducted in June 2018.
Overall, Kahl Bros. Pond Dam 1 is an essential infrastructure for water management and conservation in Macoupin County. Its strategic design and regulatory oversight ensure the safety and efficiency of water storage and discharge operations, benefiting both local communities and the environment. For water resource and climate enthusiasts, this dam serves as a noteworthy example of responsible dam construction and management practices.

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.
