Blaine Drageset dam
Blaine Drageset
Blaine Drageset is a dam located in Corson, South Dakota, owned by the Tribal Government with a primary purpose of water supply. This earth dam, completed in 1950, stands at a height of 24 feet and has a length of 620 feet. With a maximum storage capacity of 69 acre-feet and a normal storage of 60 acre-feet, the dam serves multiple purposes including fire protection, stock, and small fish pond maintenance in addition to its primary function of water supply.
Managed by the Natural Resources Conservation Service, Blaine Drageset has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam has not been inspected recently, and its emergency action plan status, risk assessment, and risk management measures are currently unknown. With a maximum discharge capacity of 744 cubic feet per second, Blaine Drageset plays a crucial role in water resource management in the region, particularly for the TR-GRAND river or stream.
Although details on the dam's current condition and emergency preparedness are lacking, Blaine Drageset remains a significant water resource structure in South Dakota. With its historical significance dating back to 1950 and its multiple beneficial purposes, this dam stands as a key feature in the water supply infrastructure of the area. For water resource and climate enthusiasts, keeping an eye on the future assessments and maintenance plans for Blaine Drageset could provide valuable insights into the sustainable management of this vital water resource.

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 Blaine Drageset
Where does the data for Blaine Drageset 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.
