Sd Noname 32 dam
Sd Noname 32
Sd Noname 32 is a privately owned dam located in Haakon, South Dakota along the TR-Cheyenne River. Built in 1960, this earth dam stands at a height of 17 feet and has a length of 560 feet, providing a storage capacity of 238 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state jurisdiction, permitting, inspection, and enforcement.
Although Sd Noname 32 has a low hazard potential and is currently in a "Not Rated" condition assessment, it has not been inspected or assessed for its emergency action plan preparedness, risk assessment, or risk management measures. The dam's primary purpose and associated structures are not specified, but it is noted that the Natural Resources Conservation Service was involved in its design. The dam's location, proximity to the Cheyenne River, and limited discharge capacity of 6000 cubic feet per second indicate its importance in managing water resources and potential flood control in the region.
Overall, Sd Noname 32 serves as a crucial infrastructure for water resource management in Haakon County, South Dakota. While it has a relatively low hazard potential, its condition assessment and emergency preparedness should be evaluated to ensure the safety and effectiveness of the dam in the face of potential climate-related challenges. Enthusiasts of water resources and climate resilience will find interest in monitoring the regulatory oversight and maintenance efforts of Sd Noname 32 to protect the surrounding community and environment.

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 32
Where does the data for Sd Noname 32 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.
