Sd Noname 80 dam
Sd Noname 80
Sd Noname 80, located in Haakon, South Dakota, is a privately owned earth dam completed in 1970 with a height of 16 feet and a storage capacity of 212 acre-feet. The dam is regulated by the South Dakota Department of Agriculture and Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations. Despite being classified as low hazard potential, the dam's condition is currently not rated as it has not been assessed recently.
The dam has a maximum discharge of 2100 cubic feet per second and serves the primary purpose of off-stream water storage. With a length of 610 feet, Sd Noname 80 plays a crucial role in managing water resources in the area, particularly for irrigation and agriculture. While the dam has not been modified in recent years and lacks detailed risk assessment and emergency action plans, its location and design suggest it is a key infrastructure for water management in the region.
As an essential structure in the St. Paul District, Sd Noname 80 is a notable feature on the Bad River off-stream. While it may not have a high-profile status or associated funding from federal agencies, its importance lies in its contribution to water resource management and its impact on the local community's livelihoods. As climate change continues to impact water availability and quality, dams like Sd Noname 80 will play a critical role in adapting to these challenges and ensuring sustainable water use 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 80
Where does the data for Sd Noname 80 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.
