Summary
This earth dam stands at a height of 25 feet with a length of 265 feet, showcasing its importance in managing water resources in the area. While its normal storage capacity is listed as zero, the dam's hazard potential is considered high, emphasizing the critical need for effective monitoring and maintenance.
Managed by the Illinois Department of Natural Resources (IDNR), Brighton Lake Dam has state jurisdiction and regulatory oversight, ensuring that it meets inspection, enforcement, and permitting requirements. Despite its moderate risk assessment rating, the condition assessment of the dam is currently listed as "Not Available," highlighting the need for further evaluation and potential risk management measures. With the last inspection conducted in July 2019, there is a focus on ensuring that emergency action plans are in place and that the dam meets safety guidelines to mitigate potential hazards.
As water resource and climate enthusiasts, the Brighton Lake Dam serves as a pivotal structure in flood risk reduction efforts within the Kansas City District. With its strategic location and significant role in managing water flow along the TRIB WEST FORK WOOD R river, the dam's condition and maintenance remain crucial for ensuring the safety and protection of surrounding communities. By staying informed about the dam's status and potential risk factors, enthusiasts can support efforts to safeguard water resources and address climate-related challenges effectively.

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.
