Summary
Constructed in 2000 by the USDA NRCS, the dam has a storage capacity of 306 acre-feet and serves the primary purpose of water resource management in the area. With a low hazard potential and a moderate risk assessment rating, the dam is regulated and inspected by the South Dakota Department of Agriculture and Natural Resources.
The dam features an uncontrolled spillway with a width of 75 feet and has a maximum discharge capacity of 1560 cubic feet per second. Although the condition assessment is not rated and the Emergency Action Plan status is unknown, the dam is considered to meet regulatory guidelines for safety measures. The risk management measures for Muth Dam are yet to be detailed, but with its storage capacity, the dam plays a vital role in water resource management for the region and contributes to climate resilience efforts.
In the event of an emergency, it is essential to ensure that the Emergency Action Plan is up to date and that the risk assessment and management measures are promptly implemented to mitigate any potential hazards associated with the dam. With its strategic location and design, Muth Dam stands as a significant infrastructure for water resource management in South Dakota and underscores the importance of sustainable practices in the face of changing climatic conditions and water availability challenges.

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.
