Summary
This earth dam stands at a height of 28 feet and has a length of 350 feet, with a storage capacity of 19 acre-feet. With a low hazard potential and a moderate risk assessment rating, this dam plays a crucial role in managing water resources in the region.
Constructed with a stone core and soil foundation, the 102 River Tributaries Dam Lt-47 features an uncontrolled spillway with a width of 18 feet. Despite its age, the dam is still in good condition and has not been rated for inspection. With no state regulation or jurisdiction, this private-owned structure is essential for preventing erosion and maintaining the stability of the surrounding area. Water resource and climate enthusiasts will appreciate the role this dam plays in safeguarding the local ecosystem.
As a part of the Kansas City District, the 102 River Tributaries Dam Lt-47 contributes to the overall water management efforts in the region. With a drainage area of 172.8 square miles and a maximum discharge capacity of 150 cubic feet per second, this dam is a vital component of the local water infrastructure. Its strategic location and design make it a valuable asset for both flood control and water conservation initiatives in Nodaway County, 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.
