Shyne 1 dam
Shyne 1
Shyne 1 is a privately owned dam in South Dakota that is regulated by the state's Department of Environment and Natural Resources. Built in 1953, this earth dam stands at a height of 25 feet and spans 700 feet across the TR-CHEYENNE river. With a storage capacity of 330 acre-feet, Shyne 1 plays a crucial role in managing water resources and flood control in the region.
Despite its low hazard potential and not being rated for condition assessment, Shyne 1 is equipped with state-permitting, inspection, and enforcement measures to ensure its safety and compliance with regulatory standards. The Natural Resources Conservation Service was responsible for designing this dam, highlighting the collaboration between private ownership and federal agencies in managing water infrastructure. With a maximum discharge capacity of 1500 cubic feet per second, Shyne 1 is a vital piece of infrastructure in the St. Paul District, providing essential water resource management in Pennington County, South Dakota.
Overall, Shyne 1 serves as a key component in the water resource management system of the region, showcasing the importance of public-private partnerships in maintaining and regulating essential infrastructure for climate resilience and water security. As water resource and climate enthusiasts, understanding the role of dams like Shyne 1 in mitigating flood risks and ensuring sustainable water supply is crucial for building a resilient and sustainable future for communities in South Dakota and beyond.
Dam data reference
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 Shyne 1
Where does the data for Shyne 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.
