Summary
Standing at a height of 10 feet and a length of 190 feet, the dam has a storage capacity of 274 acre-feet and primarily aims to mitigate flood risks in the area. With a low hazard potential and a moderate risk assessment rating, the dam is regulated by the Illinois Department of Natural Resources, ensuring state jurisdiction, permitting, inspection, and enforcement are all in place to maintain its safety and effectiveness.
Despite its remote location, the 248th Avenue Dam plays a crucial role in managing water resources and protecting the surrounding communities from potential flooding events. With a focus on flood risk reduction as its primary purpose, the dam helps to control the flow of water along the Wolf Creek, contributing to the overall resilience of the region against climate-related challenges. The dam's earth structure with buttress core type and uncontrolled spillway design further highlight its efficiency in handling water discharge and maximizing storage capacity to safeguard the area during heavy rainfall or storm events.
As a private structure, the 248th Avenue Dam underscores the importance of collaboration between public and private entities in managing water resources and adapting to changing climate conditions. With regular inspections, a designated emergency action plan, and a low hazard potential, the dam exemplifies a proactive approach to risk management and ensures the safety of the community it serves. As climate enthusiasts and water resource advocates, understanding and appreciating the critical role of infrastructure like the 248th Avenue Dam is essential in building sustainable and resilient communities for the future.

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.
