Summary
This earth dam was completed in 1955 and has a storage capacity of 230 acre-feet, with a maximum discharge of 1000 cubic feet per second. The dam is situated on the TR-BAD RIVER and falls under the regulatory jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR).
Although Sd Noname 42 has not been rated for its condition assessment, it is regularly inspected, permitted, and enforced by the state regulatory agency. The dam plays a crucial role in water resource management in the region, providing essential storage for irrigation, flood control, and other purposes. With Dusty Johnson (R) as the congressional representative for the area, the dam is part of the St. Paul District under the US Army Corps of Engineers.
Water resource and climate enthusiasts will find Sd Noname 42 to be an interesting case study in dam infrastructure and management in South Dakota. The dam's historical significance, engineering details, and state oversight provide valuable insights into the complexities of maintaining water infrastructure for both human and environmental needs. As a vital component of the local water system, Sd Noname 42 exemplifies the importance of balancing water resource development with regulatory compliance and environmental stewardship in the face 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.
