Feltman Dam 1 dam
Feltman Dam 1
Feltman Dam 1, located in Chamberlain, South Dakota, was completed in 1952 and stands at a height of 27 feet with a length of 250 feet. Managed by a private owner, the dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring proper permitting, inspection, and enforcement procedures are in place. With a storage capacity of 36 acre-feet, the dam plays a significant role in water resource management for the region.
Constructed primarily for flood control purposes, Feltman Dam 1 is classified as an earth dam, with a spillway capacity of 660 cubic feet per second. The dam's hazard potential is rated as significant, highlighting the importance of regular inspections and maintenance to ensure its structural integrity. While the condition assessment is currently listed as not rated, efforts are being made to assess and manage any potential risks associated with the dam to protect surrounding communities and the environment.
Managed by the Natural Resources Conservation Service, Feltman Dam 1 serves as a crucial infrastructure for water storage and flood protection in the Brule County area. As climate change continues to impact water resources, the proper regulation and management of dams like Feltman Dam 1 are essential in mitigating potential risks and ensuring the sustainability of water supplies for future generations.
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 Feltman Dam 1
Where does the data for Feltman Dam 1 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.
