Summary

Built in 1969 for recreational purposes, this earth dam stands at a height of 22.5 feet with a hydraulic height of 14.1 feet. It has a storage capacity of 16.4 acre-feet and covers a surface area of 2.9 acres, serving as a popular spot for outdoor activities in the region.

Despite its relatively small size, Kiblen West Dam is regulated and inspected by the Idaho Department of Water Resources, ensuring its safety and compliance with state regulations. The dam's spillway type is uncontrolled, with a maximum discharge capacity of 8 cubic feet per second. The structure's hazard potential is classified as significant, although its condition assessment is rated as fair based on the last inspection conducted in October 2016.

While Kiblen West Dam poses a moderate risk level, appropriate risk management measures are in place to mitigate any potential hazards. With its scenic location and recreational amenities, this dam continues to attract water resource and climate enthusiasts seeking outdoor adventures in the beautiful surroundings of Idaho's natural landscape.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
