Summary
Grueb, a privately owned earth dam located in Meade, South Dakota, serves as a vital water resource on the TR MOREAU river. Completed in 1951, this dam stands at a height of 21 feet and has a storage capacity of 126 acre-feet, with a maximum discharge capacity of 2800 cubic feet per second. Despite its low hazard potential and current "Not Rated" condition assessment, W. Grueb is regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring that it meets state permitting, inspection, and enforcement standards.
Managed by the St. Paul District of the US Army Corps of Engineers, W. Grueb plays a crucial role in the water management infrastructure of the region. With a primary purpose that is not explicitly defined, this dam serves various purposes that contribute to the overall water security and environmental sustainability of the area. While the dam itself has not undergone significant modifications in recent years and lacks detailed risk assessment and emergency action planning, its strategic location and operational capacity make it a key asset for water resource management in South Dakota.
The presence of W. Grueb, under the representation of Congressman Dusty Johnson, underscores the importance of maintaining and monitoring our water resources in the face of climate change challenges. As water resource and climate enthusiasts, it is essential to recognize the role of structures like W. Grueb in sustaining the ecological balance and ensuring water availability for both present and future generations. By understanding and supporting initiatives to assess and enhance the resilience of dams like W. Grueb, we can work towards a more sustainable and secure water future in South Dakota and beyond.

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.
