Summary

Completed in 1975, this earth dam, designed by Gerard Harms and Jim Abels, serves a primary purpose of recreation, offering a storage capacity of 580 acre-feet and spanning 735 feet in length. Situated on the TR-OSAGE RIVER/LK OF OZARKS, the dam not only provides recreational opportunities but also plays a vital role in flood control and water supply management within the region.

Owned privately, Treeline Lake Dam is regulated by the DAM AND RESERVOIR SAFETY PROG, ensuring that the structure meets safety standards and is regularly inspected. With a hazard potential classified as high, the dam maintains a satisfactory condition assessment as of December 2007. Despite its moderate risk rating, the dam's emergency action plan (EAP) remains unprepared, highlighting the need for continued monitoring and risk management measures to safeguard the surrounding communities and water resources.

Overall, Treeline Lake Dam serves as a significant landmark in the Kansas City District, offering not only recreational opportunities but also contributing to water resource management and climate resilience efforts in Missouri. As water resource and climate enthusiasts, understanding the importance of structures like Treeline Lake Dam is crucial in building a sustainable and resilient future for our communities and natural environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
