Summary
is a privately owned dam located on the TR MOREAU RIVER in Perkins, South Dakota. Built in 1951, this earth dam stands at a height of 20 feet and spans 300 feet in length, with a storage capacity of 62 acre-feet. Managed by the Natural Resources Conservation Service, Smaltz Bros. is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state permitting, inspection, and enforcement standards.
Despite its low hazard potential and current "Not Rated" condition assessment, Smaltz Bros. plays a crucial role in water resource management in the region. With a normal storage capacity of 48 acre-feet and a maximum discharge of 200 cubic feet per second, this dam helps regulate water flow and prevent flooding in the area. Its strategic location on the TR MOREAU RIVER underscores its importance in maintaining water quality and availability for both environmental and agricultural purposes.
As climate change continues to impact water resources and infrastructure, the monitoring and maintenance of dams like Smaltz Bros. become increasingly vital. While currently not assigned a Dam Safety Action Classification, ongoing risk assessments and management measures are essential to ensure the long-term safety and effectiveness of this structure. Water resource and climate enthusiasts will find Smaltz Bros. to be an intriguing case study in the intersection of conservation, regulation, and sustainable water management practices.

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.
