Summary
Built in 1955, this earth dam stands at a height of 26 feet with a length of 396 feet, providing a storage capacity of 26 acre-feet. The dam is regulated and permitted by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections to ensure its structural integrity and compliance with state regulations.
Despite its low hazard potential and current "Not Rated" condition assessment, Eklund #3 plays a crucial role in managing water resources in the region. With a maximum discharge capacity of 115 cubic feet per second, the dam helps control water flow and mitigate flood risks in the area. While it does not have a designated emergency action plan (EAP) or inundation maps prepared, the dam's existence contributes to the overall water management efforts in South Dakota.
Eklund #3 is a significant infrastructure asset within the St. Paul District, providing essential water storage and flood control benefits to the local community. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like Eklund #3 are vital in ensuring the resilience and sustainability of water systems in the face of evolving climatic challenges.

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.
