Summary
Constructed in 1965 by the USDA NRCS, this earth dam serves as a Fish and Wildlife Pond along the TR- Shoal Creek W West Fork. With a dam height of 25 feet and a length of 300 feet, Matway Pond Dam 1 has a storage capacity of 60 acre-feet and covers a surface area of 5 acres. The dam is regulated by the Illinois Department of Natural Resources and is subject to state inspection, permitting, and enforcement.
Despite being classified as having a low hazard potential, Matway Pond Dam 1 is considered to have a moderate risk level, with a risk rating of 3 out of 5. The dam features an uncontrolled spillway with a width of 40 feet and outlet gates also categorized as uncontrolled. The last inspection of the dam was conducted in June 2015, with no condition assessment currently available. While emergency action plans and risk management measures are not specified for the dam, it is important for water resource and climate enthusiasts to monitor the maintenance and safety of Matway Pond Dam 1 to ensure the protection of the surrounding environment and wildlife.

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.
