Reaser Stock Dam dam
Reaser Stock Dam
Reaser Stock Dam, located in Fall River, South Dakota, is a privately owned structure that serves multiple purposes in managing water resources in the region. Constructed in 1945, this earth dam stands at a height of 12 feet and has a storage capacity of 106 acre-feet, with a normal storage of 64 acre-feet. It is situated on the tributary of Horsehead Creek and is regulated by the South Dakota Department of Environment and Natural Resources.
Despite its low hazard potential, the condition of Reaser Stock Dam is currently not rated, indicating a need for further assessment and maintenance. The dam has a maximum discharge capacity of 390 cubic feet per second, ensuring effective flood control measures for the surrounding area. Managed by the Natural Resources Conservation Service, this dam plays a crucial role in water resource management and climate resilience efforts in the region.
Reaser Stock Dam stands as a testament to the importance of private infrastructure in supporting sustainable water resource management. With its strategic location and regulated operations, this earth dam continues to contribute to the overall environmental health and safety of Fall River, South Dakota, under the supervision of the state regulatory agency. For water resource and climate enthusiasts, Reaser Stock Dam serves as a fascinating example of how private ownership can play a significant role in maintaining critical water infrastructure for the benefit of the community and the 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 Reaser Stock Dam
Where does the data for Reaser Stock Dam 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.
