Summary
Completed in 1956, this earth dam stands at a height of 20 feet and spans a length of 78 feet, with a storage capacity of 56 acre-feet. Situated on the TR BAD RIVER, it is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
With a significant hazard potential, Sd Noname 211 has not been rated for its condition assessment. Despite lacking specific details on its emergency action plan (EAP), risk assessment, and other management measures, the dam remains under state jurisdiction and is subject to regular monitoring. The dam's maximum discharge capacity is recorded at 918 cubic feet per second, highlighting the importance of its role in water resource management in the area.
As a point of interest for water resource and climate enthusiasts, Sd Noname 211 serves as a vital structure in the St. Paul District managed by the US Army Corps of Engineers. While lacking some details on its operational aspects, the dam's presence on the TR BAD RIVER underscores its importance in regulating water flow and ensuring the safety of surrounding communities.

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.
