Sd Noname 147 dam
Sd Noname 147
Sd Noname 147 is a privately owned dam located in Jackson, South Dakota, along the TR-WHITE RIVER. Built in 1960, this earth dam stands at a height of 27 feet and spans 750 feet in length, with a storage capacity of 285 acre-feet. Managed by the Natural Resources Conservation Service, Sd Noname 147 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring compliance with state permitting, inspection, and enforcement requirements.
With a significant hazard potential, Sd Noname 147 has not been rated for its condition and does not have an emergency action plan in place. Despite these gaps in preparedness, the dam plays a crucial role in flood control and water storage activities in the region. It is important for water resource and climate enthusiasts to monitor the maintenance and safety measures of Sd Noname 147 to prevent potential risks and ensure the protection of downstream communities and ecosystems.
As part of the St. Paul District of the US Army Corps of Engineers, Sd Noname 147 serves as a key infrastructure for water management in South Dakota. While the dam has not been modified in recent years, ongoing risk assessments and management measures are essential to mitigate any potential threats and uphold the structural integrity of this vital resource. With Dusty Johnson (R) representing the area in Congress, there is a need for continued collaboration between federal, state, and local agencies to safeguard Sd Noname 147 and its surrounding environment for future generations.

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 Sd Noname 147
Where does the data for Sd Noname 147 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 Significant 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.
