Summary
Completed in 2008, this earth dam stands at a height of 20 feet and has a storage capacity of 72 acre-feet. The dam is situated on the TR-N Fork Whetstone River and is regulated by the South Dakota Department of Environment and Natural Resources (DENR). Despite its low hazard potential, the dam is subject to state inspections, permitting, and enforcement to ensure its safety and functionality.
Managed by Konechne Eng., Kane Dam has a moderate risk assessment rating of 3, highlighting the importance of proper risk management measures. The dam features an uncontrolled spillway with a width of 80 feet and has no outlet gates. With a drainage area of 2 square miles and a maximum discharge of 1080 cubic feet per second, the dam plays a critical role in managing water levels and flow in the region. Although its condition assessment is currently not rated, the dam's operational status is regularly monitored to mitigate any potential risks and ensure its continued effectiveness in water resource management for the community.
Overall, Kane Dam stands as a vital infrastructure for water resource management in South Dakota, contributing to flood control, water storage, and environmental sustainability in the region. With its strategic location on the TR-N Fork Whetstone River and its regulated status by the state authorities, the dam serves as a key component in the local water infrastructure network. As climate change impacts water resources, the importance of structures like Kane Dam in ensuring water security and resilience becomes increasingly significant for communities and ecosystems dependent on these resources.

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.
