Summary
Constructed in 1961 by the Natural Resources Conservation Service, this earth-type dam stands at a height of 27 feet and has a length of 531 feet. With a storage capacity of 44 acre-feet and a maximum discharge of 2040 cubic feet per second, Dale Swedland 1 serves various regulatory purposes in the state, including state permitting, inspection, and enforcement.
Despite being rated as having a low hazard potential and not having a condition assessment, Dale Swedland 1 plays a crucial role in water resource management in the region. The dam's primary purpose and associated structures are not explicitly mentioned, but its presence is vital in maintaining water levels and controlling the flow along the White River. With its location in a remote area and lack of detailed emergency response plans, there may be room for improvement in terms of ensuring the safety and resilience of this essential infrastructure.
As climate change continues to impact water resources and weather patterns, it is essential for enthusiasts and stakeholders to monitor and assess the condition of dams like Dale Swedland 1. With its historical significance and ongoing operational importance, understanding the risk management measures and emergency preparedness for this dam is crucial for ensuring the sustainability and efficiency of water resource management in South Dakota.

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.
