Sd Noname 140 dam
Sd Noname 140
Sd Noname 140 is a privately owned dam located in Jackson, South Dakota, with a critical role in water resource management. Built in 1950, this Earth-type dam stands at a height of 12 feet and has a storage capacity of 87 acre-feet, serving as a vital structure in regulating the flow of the TRIB. BAD RIVER. Despite its low hazard potential, the dam is state-regulated and undergoes regular inspections, enforcement, and permitting by the South Dakota Department of Environment and Natural Resources.
With a maximum discharge capacity of 900 cubic feet per second, Sd Noname 140 plays a crucial role in flood control and water supply management in the region. Although it is not rated for its condition assessment, the dam has not been modified in recent years and is designed to withstand various hydraulic pressures. Additionally, the surrounding area does not have inundation maps prepared, indicating the potential need for improved emergency preparedness measures in the event of a dam failure or flooding incident.
Overall, Sd Noname 140 represents a significant piece of infrastructure in South Dakota's water resource network, with its strategic location and design contributing to the overall water management system in the area. As climate change continues to impact water resources, dams like Sd Noname 140 will play a critical role in ensuring the sustainable use and conservation of water for both human consumption and environmental needs.

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 140
Where does the data for Sd Noname 140 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.
