Summary
Standing at a height of 13 feet with a length of 650 feet, the dam has a storage capacity of 109 acre-feet and a maximum discharge of 3150 cubic feet per second. Despite its low hazard potential and the absence of a condition assessment, Ruben Larosh is regulated by the South Dakota Department of Environment and Natural Resources, with state jurisdiction, permitting, inspection, and enforcement in place.
Situated along the TR-MISSONot RatedI river or stream, Ruben Larosh falls under the purview of the St. Paul District of the US Army Corps of Engineers. While it lacks specific details on purposes or primary agencies involved, the dam remains an integral part of the water resource infrastructure in the region. With its historical significance dating back over 80 years, the dam serves as a vital component for managing water resources in the area, despite not having a designated emergency action plan or a comprehensive risk assessment in place.
As a structure with a rich history and ongoing regulatory oversight, Ruben Larosh presents a compelling case study for water resource and climate enthusiasts. Its location, design features, and operational capacity highlight the intersection of human engineering with natural landscapes, showcasing the importance of sustainable water management practices in safeguarding communities against potential hazards and ensuring the long-term resilience of critical infrastructure.

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.
