Summary
Standing at a height of 32 feet and with a length of 740 feet, this earth dam has a maximum storage capacity of 553 acre-feet, making it a crucial water resource infrastructure in the region. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is regularly inspected, enforced, and permitted by state authorities to ensure its safety and functionality.
Although considered to have a low hazard potential, the condition of Stanley Smeenk Dam No.1 is currently not rated. The dam serves various purposes such as water storage and flood control, and its maximum discharge capacity is 1,920 cubic feet per second. Despite lacking certain detailed data points such as spillway type and surface area, the dam plays a vital role in managing water resources in the Butte County area. With its strategic location and design, Stanley Smeenk Dam No.1 is an essential structure for water management and climate resilience efforts in the region, supported by the Natural Resources Conservation Service as its primary designer.

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.
