Carl Kannolt Dam dam
Carl Kannolt Dam
The Carl Kannolt Dam in South Dakota stands as a testament to both engineering ingenuity and environmental stewardship. 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
- 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.
- 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.
- 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.
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, environmental 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.

About Carl Kannolt Dam
Where does the data for Carl Kannolt Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
