Jack Hunt dam
Jack Hunt
Jack Hunt is a privately owned dam located in Ziebach, South Dakota, along the TR Cheyenne River. Built in 1956, this earth dam stands at a height of 28 feet and has a length of 470 feet, providing a storage capacity of 203 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam's condition is currently not rated, indicating a need for further assessment and maintenance to ensure its safety and reliability as a water resource in the region.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Jack Hunt is subject to state regulation, permitting, inspection, and enforcement. The dam's primary purpose and associated structures are not specified, but its role in water management and flood control for the local area is crucial. Located in a remote part of the state, the dam's presence contributes to the overall water infrastructure and climate resilience efforts in South Dakota, under the oversight of the Natural Resources Conservation Service.
While Jack Hunt's emergency action plan status and risk management measures are currently unknown, its overall risk assessment falls within the moderate category. With a designated spillway type of "Uncontrolled" and a maximum discharge capacity of 2135 cubic feet per second, the dam's functionality and safety protocols are integral to mitigating potential flood risks and ensuring the sustainable management of water resources in the St. Paul District. As water resource and climate enthusiasts, staying informed about the condition and management of dams like Jack Hunt is essential for promoting effective water stewardship and resilience in the face of changing environmental conditions.

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 Jack Hunt
Where does the data for Jack Hunt 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.
