Summary
Standing at 27 feet high and spanning 393 feet in length, the dam holds a maximum storage capacity of 177 acre-feet, providing a serene water resource for outdoor enthusiasts. The dam overlooks Brushy Fork River and is regulated by the Illinois Department of Natural Resources, ensuring state jurisdiction, permitting, inspection, and enforcement measures are in place.
Despite its significant hazard potential, with a moderate risk assessment rating of 3, Rowe Lake Dam has not had its condition assessed recently. The dam's spillway type is uncontrolled, with uncontrolled outlet gates, emphasizing the importance of proper maintenance and emergency preparedness. While the dam has a history of modifications dating back to its completion, there is limited information on risk management measures, emergency action plans, and inundation maps, highlighting areas for improvement in ensuring the safety and sustainability of this water resource.
For water resource and climate enthusiasts, Rowe Lake Dam presents a unique opportunity to explore the intersection of recreational use and dam safety. With its picturesque location and potential for outdoor activities, the dam serves as a valuable asset to the community. However, continued monitoring and maintenance are essential to mitigate risks and ensure the long-term viability of this water infrastructure. As discussions around climate change and water management evolve, Rowe Lake Dam stands as a reminder of the importance of proactive stewardship in safeguarding our natural resources for future generations.

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.
