Summary
2 is a privately owned earth dam located in Mellette, South Dakota, along the tributary of the White River. Completed in 1964, this dam stands at a height of 26 feet and has a storage capacity of 29 acre-feet. With a low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations.
Owned and operated by a private entity, Ecklund No. 2 plays a crucial role in water resource management in the region, providing flood control and water storage for agricultural purposes. Despite its age, the dam has not been rated for its current condition, indicating a need for further assessment and potentially an emergency action plan in the future. The dam's location in a remote area with no associated structures highlights its importance in maintaining the health and sustainability of the surrounding ecosystem.
As climate change continues to impact water resources and infrastructure, the importance of dams like Ecklund No. 2 in managing water supply and mitigating flood risks becomes increasingly evident. With proper maintenance, monitoring, and regulatory oversight, this earth dam serves as a vital component of the water management system in South Dakota, contributing to the resilience of the local community and environment in the face of changing climate patterns.

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.
