Pasture 6en Du Swsw dam
Pasture 6en Du Swsw
Pasture 6en Du SWSw, located in Shadehill, South Dakota, is a Federal-owned Earth dam completed in 1985 for the primary purpose of serving as a Fish and Wildlife Pond. The dam stands at a height of 24 feet with a hydraulic height of 18 feet, and a length of 650 feet. It has a normal storage capacity of 175 acre-feet and covers a surface area of 16 acres, with a drainage area of 8 acres. The dam has a low hazard potential and has not been rated for its condition assessment.
Managed by the Forest Service, Pasture 6en Du SWSw is utilized for fire protection, stock, small fish pond, and recreational purposes in addition to its primary function for fish and wildlife. The dam's spillway type is uncontrolled, with a spillway width of 150 feet. The maximum discharge capacity of the dam is 1174 cubic feet per second. Despite being moderate risk-rated, the dam does not have an Emergency Action Plan prepared, and its last inspection was conducted in October 2017 with a frequency of every 10 years.
Water resource enthusiasts will be intrigued by the unique design and purpose of Pasture 6en Du SWSw, which serves as a vital habitat for fish and wildlife in the region. The dam's construction by the Forest Service showcases the importance of sustainable water management practices in maintaining biodiversity and supporting recreational activities. As a significant feature in the landscape of Shadehill, South Dakota, this dam offers a glimpse into the intricate balance between human needs and environmental conservation efforts in the area.

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 Pasture 6en Du Swsw
Where does the data for Pasture 6en Du Swsw 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.
