Summary
Built in 1950, this earth dam stands at a height of 13 feet and has a length of 700 feet, providing a storage capacity of 90 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
Despite its low hazard potential, Sd Noname 189 has not been rated for its condition assessment. Emergency action plans and risk management measures have not been documented, but the dam's structure and purpose indicate its significance for water resource management in the area. With Dusty Johnson as the representative for the St. Paul District overseeing the dam, enthusiasts of water resources and climate will find interest in monitoring the developments and maintenance of this essential infrastructure in South Dakota.
As a key part of the local water management system, Sd Noname 189 serves as a crucial structure for controlling water flow and providing storage in the region. With its location on the TR-White River and state-regulated status, this dam plays a vital role in maintaining water resources and protecting against potential hazards. Enthusiasts of water resource and climate issues will continue to track the condition and management of Sd Noname 189 to ensure its ongoing effectiveness and safety for the surrounding community and environment.

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.
