Osborne Number 2 dam
Osborne Number 2
Osborne Number 2 is a privately-owned earth dam located in Jones, South Dakota, along the TR-BAD RIVER. Built in 1959 by the Natural Resources Conservation Service, this dam stands at a height of 19 feet and has a storage capacity of 118 acre-feet. With a low hazard potential and a "Not Rated" condition assessment, Osborne Number 2 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state inspection, enforcement, and permitting requirements.
Although the dam has not been inspected recently and lacks an Emergency Action Plan (EAP), it still plays a vital role in water resource management and flood control in the area. The dam's construction was funded by the federal government and is under the jurisdiction of the St. Paul District of the US Army Corps of Engineers. Additionally, Osborne Number 2 is situated in a region represented by Dusty Johnson, a Republican Congressman, showing the importance of this structure in the local community and its impact on water resource management in South Dakota.
Overall, Osborne Number 2 serves as a key piece of infrastructure in the region, providing water storage and flood protection along the TR-BAD RIVER. While it has not been recently assessed for condition or emergency preparedness, its low hazard potential and regulatory oversight by the state ensure that it continues to fulfill its purpose effectively. As water resource and climate enthusiasts, monitoring and maintaining structures like Osborne Number 2 is essential for sustainable water management and resilience to changing 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 Osborne Number 2
Where does the data for Osborne Number 2 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.
