Summary
The dam stands at 23 feet tall and spans 365 feet in length, with a storage capacity of 81 acre-feet. The primary dam type is earth, supported by a buttress core, and the spillway type is uncontrolled with a width of 34 feet.
Managed by the Illinois Department of Natural Resources, the dam is regulated and inspected regularly to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, Timber Acres Lake Dam plays a crucial role in water resource management for the surrounding area, particularly in controlling the flow of Buckhart Creek-offstream. Despite its age, the dam has not undergone any significant modifications and its condition assessment remains unavailable.
Water and climate enthusiasts interested in the intersection of dam infrastructure, water resource management, and environmental risk assessment will find Timber Acres Lake Dam a compelling case study. With its unique design features, regulatory oversight by state authorities, and the potential impact on the local ecosystem, this dam serves as a fascinating example of the balance between human development and environmental protection in the face of changing climate conditions.

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.
