Summary
Built in 1959, this dam stands at a height of 14 feet and has a length of 1050 feet, providing a storage capacity of 170 acre-feet. Situated on the TR-Bad River, this structure is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it is regularly inspected and maintained to meet safety standards.
With a low hazard potential, Roy Stout No.1 serves as a crucial water resource for the surrounding area, with a maximum discharge capability of 6000 cubic feet per second. Although its condition assessment is currently listed as 'Not Rated', the dam continues to fulfill its primary purpose of water storage and flood control. Despite being a privately owned structure, it benefits from the oversight and expertise of the Natural Resources Conservation Service in terms of design and construction.
As an essential part of the local water management infrastructure, Roy Stout No.1 plays a vital role in safeguarding the community from potential flooding events and ensuring a stable water supply. With its strategic location on the TR-Bad River and the backing of regulatory agencies, this dam stands as a testament to the importance of effective water resource management in the face of changing climate patterns.

Dam Data Reference
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.
