Summary
This earthen dam stands at a height of 21 feet and has a storage capacity of 118 acre-feet, primarily serving as a crucial water resource for the surrounding area. Situated on the TR-Bad River Offstream, this dam plays a vital role in regulating water flow and providing essential irrigation for local agriculture.
Managed by the Natural Resources Conservation Service, Sd Noname 242 is subject to state regulations and inspections to ensure its structural integrity and safety. Despite being classified as low hazard potential, the dam's condition assessment remains unrated, highlighting the need for ongoing monitoring and maintenance. With a maximum discharge capacity of 660 cubic feet per second, this dam plays a crucial role in flood control and water management within the region, showcasing its significance for climate and water resource enthusiasts.
As part of the St. Paul District of the US Army Corps of Engineers, Sd Noname 242 stands as a testament to human ingenuity in harnessing and managing water resources for the benefit of local communities. Its presence along the Bad River Offstream not only supports agricultural activities but also contributes to the overall ecological balance of the area. With its rich history and ongoing regulatory oversight, this dam serves as a valuable asset in South Dakota's water infrastructure and a focal point for those passionate about sustainable water resource management in the face of changing climate patterns.

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.
