Summary
Built in 1940, this earth dam stands at a height of 17 feet and stretches for 600 feet along the TR Moreau river. It has a storage capacity of 120 acre-feet and a maximum discharge of 2000 cubic feet per second, serving as a crucial component in managing water resources in the region.
Despite being classified as having a low hazard potential and not yet rated for its condition, Glen Bringman plays a vital role in flood control and water storage for the area. It is subject to state permitting, inspection, and enforcement, ensuring its operational compliance and safety. With Dusty Johnson (R) serving as the Congressional Representative for the district, the dam remains a significant infrastructure for both water resource management and climate resilience efforts in South Dakota.
As water resource and climate enthusiasts, the data on Glen Bringman presents a valuable insight into the infrastructure that supports the region's water management strategies. With its historical significance and state-regulated status, this dam exemplifies the importance of maintaining and monitoring such structures to ensure the sustainable use of water resources and resilience to changing climate conditions. As efforts to address water security and climate adaptation continue, understanding the role of dams like Glen Bringman becomes crucial for developing effective strategies for a more sustainable future.

Dam Data Reference
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.
