Summary
Completed in 1960, this private-owned Earth dam spans 600 feet in length and reaches a height of 26 feet, serving as a vital structure along the TR-CHEYENNE river. Managed by the Natural Resources Conservation Service, the dam boasts a storage capacity of 416 acre-feet, ensuring water security for the surrounding area.
With a low hazard potential and a condition assessment of "Not Rated," the Carl Kannolt Dam exemplifies a commitment to safety and reliability. Despite its age, the dam continues to fulfill its primary purpose of water retention and flood control, showcasing the effectiveness of its design and construction. As a regulated structure under the jurisdiction of the South Dakota Department of Environment and Natural Resources, the dam undergoes regular inspections and enforcement measures to uphold its integrity and functionality.
Enthusiasts of water resources and climate will find the Carl Kannolt Dam a fascinating example of sustainable infrastructure in harmony with nature. Its role in water management, coupled with its historical significance and ongoing regulatory oversight, make it a noteworthy site for those passionate about the intersection of human development and environmental conservation.

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.
