Summary

Built in 1962 by the Natural Resources Conservation Service, this earth dam stands at a height of 28 feet and spans a length of 420 feet, with a storage capacity of 150 acre-feet. Despite being rated as low hazard potential and not currently assessed for condition, the dam is regulated by the South Dakota Department of Agriculture and Natural Resources, ensuring its safety and effectiveness in water resource management.

The dam's primary purpose and associated structures are not specified, indicating a focus on flood control and water storage for agricultural and environmental needs. While the dam's last inspection dates back to 1985, it is reassuring to note that the state agency responsible for permitting, inspecting, and enforcing regulations is actively involved in its oversight. The dam's location within the St. Paul District of the US Army Corps of Engineers further highlights its importance in the region's water resource management and climate resilience efforts.

As climate change continues to affect water resources and weather patterns, Samuelson Dam serves as a critical infrastructure for mitigating flood risks and ensuring water availability in Meade, South Dakota. With a history of effective operation since its completion in 1962, the dam's low hazard potential and state regulation underscore its significance in maintaining water security for the surrounding communities. As water resource and climate enthusiasts, the functionality and regulatory oversight of Samuelson Dam are key aspects to monitor for sustainable water management practices in the region.

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. 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

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, 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.
