Summary
The dam, completed in 1988, stands at a height of 28.5 feet and has a hydraulic height of 25.3 feet. With a storage capacity of 65 acre-feet and a surface area of 5 acres, Yanke plays a crucial role in supporting the local ecosystem by providing habitat for fish and wildlife.
Despite its low hazard potential and fair condition assessment, Yanke is subject to state regulation and inspection to ensure its structural integrity and operational safety. The dam's spillway, which is uncontrolled and 14 feet wide, helps manage excess water flow during periods of high discharge. The risk assessment for Yanke indicates a moderate risk level, highlighting the importance of continued monitoring and maintenance to mitigate any potential hazards.
With its scenic location and important role in supporting local wildlife, Yanke serves as a valuable resource for water and climate enthusiasts in the region. Its modest size and purposeful design make it a sustainable and environmentally conscious feature within the landscape of Valley County, Idaho.

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.
