Nd No Name 290 dam
Nd No Name 290
Nd No Name 290, located in Sioux, North Dakota, is a privately owned earth dam constructed in 1940 by USFWS for fire protection, stock, and small fish pond purposes. The dam stands at 16 feet in height and spans 350 feet in length, with a storage capacity of 60 acre-feet. Situated on the Leaf on the Hill Creek-TR, this structure is regulated by the NDSWC and maintained by the state with regular inspections and enforcement measures in place to ensure its safety and functionality.
Despite being classified as having a low hazard potential, Nd No Name 290 is deemed to have a moderate risk level, with a risk assessment rating of 3. The dam features an uncontrolled spillway with a width of 20 feet and has not been modified since its completion. While it has not been given a condition assessment rating, the structure has not been rated as of the last inspection in 1980. Emergency action plans, inundation maps, and risk management measures are not currently in place, highlighting areas for improvement in the event of a potential hazard or emergency situation.
With its historical significance dating back to the mid-20th century, Nd No Name 290 serves as a vital component of the local water resource infrastructure, providing essential services for fire protection and agricultural purposes. As climate change continues to impact the region, it is crucial for stakeholders to monitor and address any potential risks associated with the dam to ensure its long-term sustainability and resilience in the face of evolving 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 Nd No Name 290
Where does the data for Nd No Name 290 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.
