Summary
With a height of 13 feet and a length of 590 feet, the dam has a storage capacity of 198 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state jurisdiction, permitting, inspection, and enforcement.
While Henry Siebrasse has a low hazard potential and is not currently rated for condition assessment, it serves as a vital structure for water resource management in the region. The dam plays a crucial role in mitigating floods, providing irrigation water, and maintaining water supply for various purposes. Situated in a picturesque landscape, the dam is a significant feature in the local ecosystem and contributes to the overall resilience of the area in the face of climate variability.
Although lacking in detailed risk assessment and emergency preparedness measures, Henry Siebrasse stands as a testament to historical infrastructure development in South Dakota. As climate change continues to impact water resources, the importance of maintaining and improving such structures becomes increasingly evident. Water resource and climate enthusiasts can appreciate the role of Henry Siebrasse in sustaining the region's water security and resilience in the face of a changing climate.

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.
