Summary

Built in 1957 and managed by the Natural Resources Conservation Service, this earth dam stands at 14 feet high and spans 392 feet in length, with a storage capacity of 95 acre-feet. Despite its relatively small size, the dam plays a significant role in water resource management in the area, providing a normal storage capacity of 22 acre-feet and a maximum discharge of 610 cubic feet per second.

The dam is state-regulated and falls under the jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR), with permitting, inspection, and enforcement all carried out by the state agency. Classified as having a significant hazard potential, the condition assessment of Sd Noname 195 is currently listed as "Not Rated," indicating a need for further evaluation and potential risk management measures. While details on emergency action plans, inundation maps, and risk assessment are not available, the dam's presence underscores the importance of monitoring and maintaining infrastructure to mitigate potential hazards and ensure long-term resilience in the face of changing climate conditions.

With its proximity to the city of Philip and under the congressional representation of Dusty Johnson (R), Sd Noname 195 serves as a vital component of water resource management in the region. As water resource and climate enthusiasts, staying informed about the condition and regulatory oversight of dams like Sd Noname 195 is crucial for understanding the interconnectedness of water infrastructure, environmental sustainability, and community resilience in the face of evolving climatic challenges.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
