Summary
This earth dam stands at a height of 24 feet, with a hydraulic height of 17 feet and a structural height of 28 feet. It spans 1175 feet in length and has a storage capacity of 1590 acre-feet, serving as a vital resource for the surrounding area.
The primary purpose of Kadoka (Nid) is to support fish and wildlife, with a surface area of 255 acres and a maximum discharge of 6400 cubic feet per second. Despite its high hazard potential, the dam's condition is currently not rated, with the last inspection conducted in May 2012. While the risk assessment indicates a moderate risk level, detailed risk management measures and emergency preparedness information are not provided in the available data.
With its strategic location on White Willow Creek and the critical role it plays in supporting local ecosystems, Kadoka (Nid) is a significant water resource in South Dakota. As climate change continues to impact water availability and quality, understanding and maintaining the infrastructure of dams like Kadoka (Nid) will be crucial for ensuring sustainable water management in the region.

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.
