Summary
The dam, situated on the TRIB LONG CREEK, serves a primary purpose of recreation and is classified as an Earth dam with a Buttress core type. While specific details such as height, length, and volume are not available, the dam is noted to have a high hazard potential, with a moderate risk assessment rating.
Despite limited information on its construction and specifications, the Lake of The Woods 2 Dam stands as a crucial element in the local water resource management system. The dam's operation is subject to state regulations, inspections, and enforcement, ensuring its structural integrity and safety for surrounding communities. With its uncontrolled spillway type and high hazard potential, the dam's risk management measures play a vital role in mitigating potential threats and safeguarding downstream areas from flooding.
While the Lake of The Woods 2 Dam may lack certain detailed data points, its essential role in providing recreational opportunities and water resource management in Illinois cannot be understated. With ongoing state oversight and a commitment to safety and risk assessment, this dam remains a key asset in maintaining the delicate balance between water conservation and public safety in the region.

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.
