Summary
Bierman is a privately owned dam located in Ziebach, South Dakota, along the TR MOREAU river. This earth dam stands at a height of 17 feet and has a length of 600 feet, with a storage capacity of 99 acre-feet. Completed in 1948, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and current "Not Rated" condition assessment, R. Bierman plays a crucial role in managing water resources in the area. With a normal storage capacity of 50 acre-feet and a maximum discharge of 9000 cubic feet per second, the dam serves important purposes such as flood control, irrigation, and water supply. Although the dam has not been recently inspected or assessed for risk management, it remains a key infrastructure for water resource management in the region.
Owned by a private entity and situated within the St. Paul District of the US Army Corps of Engineers, R. Bierman represents a significant component of the local water infrastructure. With its strategic location and capacity to store and regulate water flow, the dam contributes to the overall resilience of the region in the face of changing climate conditions. Enthusiasts of water resources and climate management would find R. Bierman's history and operational details to be of interest in understanding the intersection of water resource management and climate resilience efforts.

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.
