Summary
The dam stands at a height of 25 feet with a hydraulic height of 24 feet and a structural height of 28 feet. With a storage capacity of 24 acre-feet and a maximum discharge of 16.4 cubic feet per second, Yearns Dam is designed primarily for low hazard potential and is classified as an earth dam with a stone core and soil foundation.
The dam spans a length of 250 feet and covers a surface area of 14 acres, within a drainage area of 717 acres. It is situated on the TR-South Fork Middle Fabius river and falls under the jurisdiction of the Kansas City District. Despite not being regulated by the state, Yearns Dam has undergone an inspection in 1999 and is categorized as having a moderate risk assessment level of 3. Emergency action plans and inundation maps are yet to be prepared, but the dam is reported to meet safety guidelines.
Owned privately, Yearns Dam does not feature any associated structures and lacks outlet gates. The spillway type is uncontrolled with a width of 10 feet. The dam, with no locks, has a normal storage capacity of 16 acre-feet and has not been rated for condition assessment. With its strategic location and multi-purpose design, Yearns Dam stands as a vital water resource management structure contributing to the local ecosystem and community in Fabius, Missouri.

Dam Data Reference
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.
