Summary
Completed in 1953, this earth-type dam stands at a height of 12 feet and stretches 650 feet in length, with a maximum storage capacity of 90 acre-feet. Despite its low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), which oversees its permitting, inspection, and enforcement processes.
Owned and operated by a private entity, Sd Noname 106 falls under the jurisdiction of the state of South Dakota and is situated along the TR LITTLE MISSONot RatedI RIVER. Although its condition assessment is listed as "Not Rated," the dam remains in a relatively stable condition. Managed by the Natural Resources Conservation Service, the dam has not been modified in recent years and lacks detailed risk assessment and emergency preparedness measures. With a maximum discharge capacity of 250 cubic feet per second, Sd Noname 106 serves as a crucial infrastructure for water resource management in the region.
For water resource and climate enthusiasts, Sd Noname 106 represents a unique case study of a privately-owned dam in a rural setting. With its historical significance dating back to the early 1950s, the dam stands as a testament to the importance of proper regulation and maintenance practices in ensuring the safety and integrity of water infrastructure. As climate change continues to impact water resources, the need for comprehensive risk assessment, emergency preparedness, and sustainable management measures for dams like Sd Noname 106 becomes increasingly evident.

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.
