Sd Noname 265 dam
Sd Noname 265
Sd Noname 265 is a private dam located in Haakon, South Dakota, along the TR-Cheyenne River. Built in 1958, this earth dam stands at a height of 24 feet and has a storage capacity of 77 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources and undergoes regular inspections, enforcement, and permitting processes to ensure its safety and compliance with state regulations.
Despite its low hazard potential and current condition being rated as "Not Rated," Sd Noname 265 plays a crucial role in water resource management in the region. With a normal storage capacity of 33 acre-feet and a maximum discharge rate of 140 cubic feet per second, this dam serves as a vital infrastructure for flood control, irrigation, and water supply. The dam's location within the St. Paul District and under the oversight of the Natural Resources Conservation Service further emphasizes its significance in sustaining water resources for the community.
As a part of the larger water management system, Sd Noname 265 contributes to the overall resilience of the area against water-related challenges and fluctuations in climate. With its strategic position along the Cheyenne River, this dam not only helps mitigate flood risks but also supports agricultural activities and environmental sustainability in the region. Its history, design, and operational features make Sd Noname 265 a valuable asset for water resource and climate enthusiasts interested in understanding the intersection of infrastructure, regulation, and environmental stewardship.

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 265
Where does the data for Sd Noname 265 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.
