Rosette Dam dam
Rosette Dam
Rosette Dam in South Dakota, completed in 1937, stands as a testament to the engineering prowess of the Works Progress Administration (WPA). This earthen dam on Snake Creek Tributary boasts a height of 17 feet and a storage capacity of 283 acre-feet, serving as a vital water resource for the region. While its primary purpose is not specified, the dam's low hazard potential and moderate risk assessment highlight its importance in mitigating potential flooding and ensuring water security for the local community.
Managed by the South Dakota Department of Agriculture and Natural Resources (DANR), Rosette Dam undergoes regular state inspections and enforcement to maintain its structural integrity. Despite being uncontrolled, the dam features a spillway width of 50 feet to manage excess water flow during heavy rainfall events. With Congressman Dusty Johnson overseeing the area, Rosette Dam plays a crucial role in water management and climate resilience efforts in the Edmunds County region. As a key infrastructure project, it serves as a critical component in the overall water resource management strategy for the area.
With its historic significance and practical utility, Rosette Dam serves as a vital water resource infrastructure in South Dakota. As climate change impacts intensify, the dam's role in ensuring water security and flood protection becomes increasingly crucial. As efforts to enhance its risk management measures continue, Rosette Dam stands as a testament to the intersection of engineering innovation, environmental stewardship, and community resilience in the face of evolving climate challenges.

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 Rosette Dam
Where does the data for Rosette 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.
