Summary

Built in 1957, this private-owned earth dam serves multiple purposes, including fire protection, stock maintenance, and serving as a fish and wildlife pond. With a structural height of 26 feet and a length of 250 feet, the dam holds a normal storage capacity of 25 acre-feet and covers a surface area of 1 acre, all within a drainage area of 38.4 square miles.

Despite its low hazard potential, Kolkmeyer Lake Dam is subject to regular monitoring and assessment, with a moderate risk rating. The dam features an uncontrolled spillway type with no outlet gates, reflecting a design that prioritizes safety and efficiency. While it is not regulated by the state and lacks a formal emergency action plan, the dam's risk management measures ensure its continued functionality and resilience in the face of potential climate-related challenges.

As part of the Kansas City District, Kolkmeyer Lake Dam serves as a vital component of the local ecosystem, providing habitat for fish and wildlife while also offering recreational opportunities for the community. With its strategic location on TR-SNI-A-BAR CREEK, the dam exemplifies the importance of sustainable water resource management in the face of changing climate patterns.

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.
