Summary
This earth dam, with a height of 13 feet and a hydraulic height of 9 feet, was completed in 2014 and has a storage capacity of 225 acre-feet. Situated on the High Line Canal and Deep Creek, the dam covers a surface area of 33.2 acres and features an uncontrolled spillway with a width of 60 feet.
Despite its low hazard potential and satisfactory condition assessment, Kinyon Pond Dam is regulated by the Idaho Department of Water Resources, which oversees its permitting, inspection, and enforcement. The dam's outlet gates consist of slide (sluice gate) mechanisms, and it is located within the jurisdiction of Twin Falls County. The last inspection was conducted in May 2014, with a scheduled inspection frequency of 5 years.
With its moderate risk assessment and adherence to state regulatory standards, Kinyon Pond Dam serves as a vital component of the local irrigation infrastructure in the region. Water resource and climate enthusiasts will find this dam to be an intriguing example of sustainable water management practices in Idaho, contributing to the efficient distribution of water for agricultural purposes in the area.

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.
