Summary
Built in 1958, this earth dam stands at 27 feet high and spans 140 feet in length, with a storage capacity of 21 acre-feet. The dam overlooks the TRIB TOWN BRANCH and LAMOINE RIVER, providing a picturesque backdrop for outdoor enthusiasts and nature lovers.
While the dam is categorized as having a low hazard potential, it is regulated and inspected by the Illinois Department of Natural Resources to ensure its safety and compliance with state regulations. The spillway, with a width of 23 feet, is uncontrolled, and the outlet gates operate in the same manner. Despite the moderate risk assessment rating, the dam continues to serve its recreational purpose, attracting visitors to its tranquil waters and surrounding landscape.
In the event of an emergency, the dam has protocols in place, as indicated by the inspection frequency of 5 years. Although the condition assessment is currently unavailable, efforts are made to manage any potential risks associated with the structure. With its rich history and serene setting, Mccormick Pond Dam remains a notable feature in the Illinois water resource and climate conservation landscape.

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.
