Summary
This earth dam stands at 26 feet in height with a length of 625 feet, serving primarily for grade stabilization along the Thill Branch river. With a storage capacity of 205 acre-feet and a surface area of 7.8 acres, it plays a crucial role in managing water resources in the region.
Despite being categorized as having a low hazard potential, the dam is considered to have a moderate risk level, with a maximum discharge of 1162 cubic feet per second. The spillway, which is uncontrolled and 80 feet wide, helps regulate water flow during periods of heavy rainfall. With no outlet gates and a drainage area of 249.6 square miles, the dam's primary purpose is to prevent erosion and stabilize the surrounding land, contributing to overall water resource management in the area.
As a significant piece of infrastructure in the Kansas City District, the 102 River Tributaries Dam 18 serves as a testament to the importance of earth dams in maintaining water quality and stream health. With its design focused on grade stabilization and its moderate risk level closely monitored, this dam stands as a vital component in the region's water resource and climate resilience efforts.

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.
