Summary
Built in 1935, this earth dam stands at 15 feet in height and stretches 950 feet in length, with a storage capacity of 170 acre-feet. The dam is state-regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring that it undergoes regular inspections, permitting, and enforcement measures to maintain its safety and integrity.
Despite its low hazard potential and ungraded condition assessment, Sd Noname 143 plays a crucial role in managing water resources and protecting against potential flooding along the TR-BAD River. With a maximum discharge capacity of 6500 cubic feet per second, this dam helps to control water flow and provides vital water storage for the surrounding area. Although specific purposes and associated structures are not listed, the dam serves as an important infrastructure element in the region, contributing to water resource management and climate resilience efforts.
As a part of the St. Paul District, Sd Noname 143 is overseen by the U.S. Army Corps of Engineers (USACE) and is situated within the congressional district represented by Dusty Johnson (R). While the dam's emergency action plan (EAP) status and risk assessment details are not provided, the dam's presence and operational features demonstrate its significance in safeguarding the local community and environment from potential water-related risks.

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.
