Sd Noname 124 dam
Sd Noname 124
Sd Noname 124 is a private earth dam located in Pennington, South Dakota, along the TR-RAPID CREEK. Constructed in 1950, this dam stands at a height of 9 feet and has a storage capacity of 72 acre-feet. With a low hazard potential and a "Not Rated" condition assessment, Sd Noname 124 is regulated and inspected by the South Dakota Department of Environment and Natural Resources.
Managed by the Natural Resources Conservation Service, Sd Noname 124 serves as a vital water resource in the region, providing a normal storage capacity of 36 acre-feet. Although the dam has not been rated for its condition, it meets state permitting and inspection requirements, ensuring its safety and functionality for the surrounding community. The dam's maximum discharge capacity is 360 cubic feet per second, helping to mitigate flood risks in the area.
Situated in a picturesque location with a latitude of 43.975 and longitude of -103.075, Sd Noname 124 plays a crucial role in water management and climate resilience in South Dakota. With Dusty Johnson (R) as the Congressional Representative for the region, this dam represents a collaborative effort between private owners, state regulators, and federal agencies to safeguard water resources and protect against potential hazards.
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 Sd Noname 124
Where does the data for Sd Noname 124 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.
