Summary
This dam, with a height of 23 feet and a length of 400 feet, serves the primary purpose of water storage on a tributary of the White River. With a maximum storage capacity of 129 acre-feet and a normal storage level of 95 acre-feet, the dam plays a crucial role in managing water resources in the area.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), the Little Trickle Tube Dam is regulated, permitted, inspected, and enforced by the state agency. Despite being classified as a low hazard potential structure, the dam's condition remains unrated. With a maximum discharge capacity of 2200 cubic feet per second, the dam is equipped to handle inflow during periods of high precipitation or snowmelt, ensuring the safety and stability of the surrounding area.
For water resource and climate enthusiasts, the Little Trickle Tube Dam serves as a valuable asset in water management and flood control efforts in South Dakota. Its location, design, and functionality contribute to the overall resilience of the region's water infrastructure, highlighting the importance of sustainable water resource management practices in mitigating the impacts of changing climate conditions.

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.
