Summary

Constructed in 1965 by the Soil Conservation Service (SCS), this private dam serves a primary purpose of recreation, offering a serene escape for visitors to enjoy the beauty of the surrounding area. With a height of 15 feet and a length of 580 feet, the dam holds a storage capacity of 52 acre-feet, providing a vital resource for the local community.

Managed by the Illinois Department of Natural Resources (IDNR), Kazimer Lake Dam is subject to regular inspections and enforcement measures to ensure its safety and integrity. With a significant hazard potential and a moderate risk assessment rating, the dam plays a crucial role in flood control and water supply for the region. Despite its age, the dam continues to fulfill its function effectively, showcasing the importance of proper maintenance and monitoring in the face of changing climate conditions.

As a focal point for outdoor recreation and a key component of water resource management in McHenry County, Kazimer Lake Dam serves as a reminder of the interconnectedness between human activities, natural ecosystems, and climate impacts. With its scenic location on the tributary of Nippersink Creek, the dam stands as a symbol of resilience and stewardship in the face of environmental challenges. Visitors and enthusiasts alike can appreciate the beauty and significance of this structure while also recognizing the ongoing efforts to ensure its safety and sustainability for future generations.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
