Tewaukon Pool 7a Dam dam
Tewaukon Pool 7a Dam
Tewaukon Pool 7a Dam, located in Sargent County, North Dakota, is a federally-owned structure managed by the US Fish and Wildlife Service. Completed in 1960, this earth dam stands at a height of 7 feet and serves primarily as a fish and wildlife pond along the Wild Rice River. With a maximum storage capacity of 295 acre-feet and a normal storage level of 77 acre-feet, the dam covers a surface area of 52 acres and has a drainage area of 0.18 square miles.
The dam's spillway, with a controlled design and a width of 9 feet, helps regulate water flow and prevent overflow during heavy rains or high water levels. Despite its low hazard potential and satisfactory condition assessment as of October 2020, the dam is subject to regular inspections by the Fish and Wildlife Service to ensure its continued safety and functionality. With a very high risk assessment rating of 1, the dam's risk management measures are crucial in mitigating potential threats and safeguarding the surrounding environment and communities.
Overall, Tewaukon Pool 7a Dam plays a vital role in supporting fish and wildlife habitats in the area, while also serving as a key infrastructure for water resource management along the Wild Rice River. As climate change continues to impact water availability and quality, the importance of maintaining and monitoring dams like Tewaukon Pool 7a Dam becomes increasingly significant for ensuring sustainable water use and conservation practices in the region.

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 Tewaukon Pool 7a Dam
Where does the data for Tewaukon Pool 7a Dam 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.
