Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
