Rae Number 1 dam
Rae Number 1
Rae Number 1 is a private earth dam located in South Dakota, specifically in Jones County, with a height of 25 feet and a length of 306 feet. Completed in 1953, this dam serves as a crucial infrastructure on the TRIB-BAD RIVER, regulated by the South Dakota Department of Environment and Natural Resources (DENR). With a storage capacity of 21 acre-feet and a maximum discharge of 1134 cubic feet per second, Rae Number 1 plays a significant role in water resource management in the region.
Despite being classified as a low hazard potential structure with a condition assessment of "Not Rated," Rae Number 1 has not been inspected in recent years. The dam's emergency action plan (EAP) status, risk assessment, and risk management measures are also not readily available, raising concerns about the readiness and preparedness in case of emergencies. With the involvement of the St. Paul District of the US Army Corps of Engineers (USACE) in the ownership and management of Rae Number 1, there is a need for updated information and measures to ensure the safety and sustainability of this critical water resource infrastructure.
As water resource and climate enthusiasts, it is essential to monitor and advocate for proper management and maintenance of dams like Rae Number 1 to prevent potential risks and ensure efficient water utilization. Collaboration between private owners, state regulatory agencies, and federal entities like the USACE is crucial in implementing necessary measures, conducting regular inspections, and updating emergency action plans to safeguard communities and ecosystems dependent on this vital water resource infrastructure. By staying informed and engaged, enthusiasts can contribute to the resilience and sustainability of water resources in the face of climate challenges.
Dam data reference
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 Rae Number 1
Where does the data for Rae Number 1 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.
