Sd Noname 205 dam
Sd Noname 205
Sd Noname 205, a privately owned dam located in Midland, South Dakota, was completed in 1956 and stands at a height of 26 feet. The dam, constructed for the primary purpose of water resource management along the TR Bad River, has a storage capacity of 310 acre-feet and a maximum discharge rate of 550 cubic feet per second. Despite being of Earth dam type and having uncontrolled spillways, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR) to ensure its safety and compliance with state regulations.
With a significant hazard potential and a moderate risk assessment rating, Sd Noname 205 is closely monitored for any potential safety concerns. Although its condition assessment is currently listed as "Not Rated," the dam's risk management measures and emergency action plan readiness remain undisclosed. As one of the many structures under the jurisdiction of the St. Paul District of the US Army Corps of Engineers, Sd Noname 205 plays a vital role in water resource management in the Haakon County area, serving as a critical infrastructure for flood control and water supply purposes.
As water resource and climate enthusiasts, it is essential to recognize the importance of dams like Sd Noname 205 in ensuring water security and mitigating risks associated with extreme weather events. By understanding the regulatory oversight, storage capacity, and risk assessment of such structures, we can better appreciate their role in safeguarding communities and ecosystems against potential water-related hazards. The data on Sd Noname 205 serves as a reminder of the ongoing efforts to manage and maintain our water infrastructure for a sustainable and resilient future.

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 Sd Noname 205
Where does the data for Sd Noname 205 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 Significant 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.
