Silver Creek Watershed Dt #4 dam
Silver Creek Watershed Dt #4
Silver Creek Watershed Dt #4 is a local government-owned dam located in Minnehaha, South Dakota. Designed by USDA NRCS and completed in 1962, this earth dam stands at a height of 22 feet and has a storage capacity of 215 acre-feet. Situated on the Silver Creek river, the dam plays a crucial role in regulating water flow and managing flood risks in the area.
Managed by the South Dakota Department of Environment and Natural Resources, Silver Creek Watershed Dt #4 is state-regulated and undergoes regular inspections, enforcement, and permitting to ensure its safety and functionality. With a low hazard potential and a condition assessment of "Not Rated," the dam serves as a key infrastructure for water resource management in the region. Despite being non-rated, the dam's design and construction by the Natural Resources Conservation Service highlight the importance of sustainable water management practices in mitigating climate change impacts.
As a part of the St. Paul District, Silver Creek Watershed Dt #4 contributes to the overall water resource management efforts in the state. With a drainage area of 2 square miles and a maximum discharge capacity of 1350 cubic feet per second, the dam plays a crucial role in protecting downstream communities from potential flooding events. With its strategic location and design, this dam serves as a vital asset in maintaining water security and climate resilience in the Silver Creek watershed.

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 Silver Creek Watershed Dt #4
Where does the data for Silver Creek Watershed Dt #4 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.
