Summary
Built in 1956, this earth dam stands at a height of 19 feet and has a storage capacity of 289 acre-feet, with a maximum discharge capability of 4200 cubic feet per second. The dam is situated on the TR-Grand River and is under the jurisdiction of the South Dakota Department of Environment and Natural Resources.
Managed by the Natural Resources Conservation Service, Beer Mug Dam plays a crucial role in regulating water flow and providing essential irrigation for agricultural activities in the area. Despite being classified as having a low hazard potential, the dam's condition is currently not rated, highlighting the need for regular inspections and maintenance to ensure its continued safety and effectiveness. With its strategic location and significant contribution to water resource management, Beer Mug Dam stands as a testament to human ingenuity in harnessing and preserving crucial natural resources.
As a key component in the water infrastructure of South Dakota, Beer Mug Dam underscores the importance of sustainable water management practices in the face of climate change challenges. With its history dating back to the mid-20th century, the dam continues to serve as a critical asset for water supply, flood control, and agricultural development in the region. As water resource and climate enthusiasts, understanding the role and significance of structures like Beer Mug Dam is essential in promoting resilience and sustainability in the face of evolving environmental 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.
