Summary
This earth dam, completed in 1962, stands at a height of 30 feet and spans a length of 460 feet, with a maximum storage capacity of 96 acre-feet. The dam is situated on the Thill Branch river, within the Kansas City District of Missouri.
With a low hazard potential and a moderate risk assessment rating, the 102 River Tributaries Dam 12 serves as a crucial component in managing water resources and mitigating potential risks in the region. The dam, constructed with a stone core and soil foundation, features an uncontrolled spillway with a width of 60 feet to handle maximum discharge of 1014 cubic feet per second. Despite not being regulated by the state, this dam plays a vital role in grade stabilization and flood control efforts in the area.
As a key infrastructure in the local water management system, the 102 River Tributaries Dam 12 remains in a condition that is currently not rated, but its design and purpose highlight its importance in maintaining the safety and sustainability of the surrounding environment. With a focus on managing surface water and drainage in the region, this dam represents a collaborative effort between local government entities and the USDA NRCS to ensure effective water resource management and climate resilience in Missouri.

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.
