Saville Number 1 dam
Saville Number 1
Saville Number 1, located in Jones, South Dakota, is a privately owned earth dam constructed in 1953 with a height of 25 feet and a length of 582 feet. This structure, managed by the Natural Resources Conservation Service, serves the purpose of water resource management along the TRIB-BAD RIVER. With a maximum storage capacity of 25 acre-feet and a normal storage of 15 acre-feet, the dam plays a crucial role in regulating water flow and mitigating flood risks in the region.
Despite being classified as having a low hazard potential and not yet rated for condition assessment, Saville Number 1 is subject to state regulations and inspections by the South Dakota Department of Environment and Natural Resources. The dam is equipped with state-permitted outlets and emergency action plans, ensuring that any potential risks are managed efficiently. With Dusty Johnson (R) representing the area in Congress, the dam's safety and functionality are under constant scrutiny and oversight to protect both the local community and the environment.
As a key infrastructure in the St. Paul District managed by the US Army Corps of Engineers, Saville Number 1 stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions. The dam's strategic location and design enable it to effectively control water flow and contribute to the overall sustainability of the region. With its vital role in flood control and water storage, Saville Number 1 exemplifies the intersection of engineering excellence and environmental stewardship in safeguarding our water resources for future generations.

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 Saville Number 1
Where does the data for Saville 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.
