Summary
The dam stands at a height of 35 feet and has a storage capacity of 72 acre-feet, with a maximum discharge rate of 225 cubic feet per second. Despite its low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources and undergoes regular inspections, permitting, and enforcement.
Situated on the TR-MISSONot RatedI river or stream, Kroupa Dam serves as a vital water resource for the surrounding area, providing irrigation and flood control benefits. Although the primary purpose of the dam is not specified, its normal storage capacity of 60 acre-feet ensures a reliable water supply for agricultural and environmental needs. The dam's condition is currently rated as "Not Rated," indicating a need for further assessment and monitoring to ensure its ongoing safety and functionality.
Overall, Kroupa Dam represents a key piece of infrastructure in South Dakota's water management system, with a long history of service to the community. While its specific purposes and design details may require additional clarification, the dam's strategic location, low hazard potential, and state regulatory oversight make it a noteworthy asset for water resource and climate enthusiasts interested in sustainable infrastructure development and management.

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.
