B. Silverman Dam dam
B. Silverman Dam
B. Silverman Dam, located in Ziebach, South Dakota, along Pretty Creek, was completed in 1940 by Ducks Unlimited. This private dam, standing at a height of 21 feet and stretching 560 feet in length, serves as a crucial water resource infrastructure in the region. With a storage capacity of 490 acre-feet and a low hazard potential, this earth-type dam plays a significant role in regulating water flow and providing essential water supply for the surrounding area.
Managed by the South Dakota Department of Agriculture and Natural Resources, B. Silverman Dam is subject to state regulatory oversight, including regular inspections and enforcement measures. Despite being last inspected in 1986 and rated as "Not Rated" in terms of condition assessment, the dam is considered to have a moderate risk level, emphasizing the importance of ongoing monitoring and risk management practices. Additionally, the dam features an uncontrolled spillway with a width of 40 feet, capable of managing a maximum discharge of 1642 cubic feet per second.
While the primary purpose of B. Silverman Dam is not explicitly stated, its role in water storage and flood control is evident. As a key component of the local water infrastructure, this dam contributes to the overall water resource management efforts in the region. With its historical significance and ongoing importance in water regulation, B. Silverman Dam stands as a testament to the intersection of human engineering and environmental stewardship in ensuring sustainable water resource practices.

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 B. Silverman Dam
Where does the data for B. Silverman 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.
