Etbauer Dam dam
Etbauer Dam
Etbauer Dam, located in Buffalo, South Dakota, was completed in 1952 and stands at a height of 28 feet with a length of 1020 feet. Managed by a private owner, the dam plays a crucial role in regulating water flow in the TR-MISSONot RatedI river or stream. With a maximum storage capacity of 119 acre-feet and a normal storage of 43 acre-feet, the dam helps in flood control and water supply management in the region.
This Earth-type dam, designed by the Natural Resources Conservation Service, has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. While the dam has not been inspected recently, it is under state regulation and inspection, ensuring its safety and compliance with standards. With a maximum discharge capacity of 660 cubic feet per second, Etbauer Dam continues to contribute to water resource management and climate resilience efforts in South Dakota.
Despite its modest size and limited associated structures, Etbauer Dam remains a critical infrastructure in the region, providing essential services for water supply, flood control, and environmental conservation. As climate change impacts water resources, the importance of well-maintained dams like Etbauer in ensuring water security and resilience to extreme weather events cannot be overstated. With ongoing state oversight and regulation, Etbauer Dam stands as a testament to the importance of sustainable water management practices in the face of a changing climate.

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 Etbauer Dam
Where does the data for Etbauer 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.
