Summary
The earth dam, standing at 24 feet tall, creates a reservoir with a normal storage capacity of 114 acre-feet and a max storage of 179 acre-feet. The dam spans 720 feet in length and is situated on TR-COON CR, providing a serene backdrop for outdoor enthusiasts to enjoy water-based activities.
Despite being privately owned, Ehrlick Lake Dam falls under the jurisdiction of the Kansas City District and is regulated by the state of Missouri. With a significant hazard potential and moderate risk assessment, the dam has not been rated for its condition. While it has not been inspected since July 1980, the dam's emergency action plan status and risk management measures remain undisclosed. The dam's spillway, an uncontrolled type, has a width of 30 feet to manage a max discharge of 221 cubic feet per second.
For water resource and climate enthusiasts, Ehrlick Lake Dam offers a glimpse into the intricate balance between human recreation and environmental stewardship. With its modest surface area of 5 acres and drainage area of 172.8 square miles, the dam serves as a vital piece of infrastructure in managing water resources in the region. As discussions around dam safety and risk management continue to evolve, Ehrlick Lake Dam stands as a testament to the importance of balancing human needs with the preservation of our natural ecosystems.

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.
