Summary
Completed in 1955, this private Earth dam stands at a height of 33 feet and has a storage capacity of 388 acre-feet, with a normal storage level of 265 acre-feet. The dam's primary purpose is for recreation, offering a surface area of 22 acres for activities such as fishing, boating, and wildlife viewing.
Despite its recreational benefits, Boulanger Lake Dam poses a high hazard potential due to its condition being labeled as "Not Rated." This raises concerns about the dam's ability to withstand extreme weather events or unforeseen emergencies. While the dam has not been inspected recently and lacks an Emergency Action Plan (EAP), its location on TR Hickory Lick Creek within the Kansas City District underlines the importance of regular maintenance and oversight to ensure the safety of surrounding communities and water resources.
As water resource and climate enthusiasts, it is crucial to monitor the state of Boulanger Lake Dam and advocate for proper assessment and risk management measures to mitigate potential hazards. By staying informed and pushing for regulatory agencies to prioritize inspection and maintenance, we can help protect this vital water infrastructure and preserve the recreational opportunities it provides for the community in Warren County, Missouri.

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.
