Summary

Built in 1958 by the Natural Resources Conservation Service, this earth dam stands at a height of 13 feet and has a length of 360 feet. With a storage capacity of 156 acre-feet, it serves the primary purpose of water storage and management in the region.

Despite being classified as having a low hazard potential, Sd Noname 33 is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place. The dam has not been rated for its condition assessment, and emergency action plans and risk assessment measures are yet to be completed or updated. However, with a maximum discharge capacity of 1680 cubic feet per second, the dam plays a crucial role in flood control and water resource management along the Bad River.

Overall, Sd Noname 33 serves as a vital infrastructure for water resource management in the region, providing storage and regulation of water flow along the TR-BAD RIVER. Despite its low hazard potential, ongoing monitoring and maintenance are essential to ensure the safety and effectiveness of this earth dam in the face of climate variability and changing hydrological patterns. Climate and water resource enthusiasts can appreciate the significance of Sd Noname 33 as a key component in the sustainable management of water resources in South Dakota.

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.
