Summary

Constructed in 1954 by the Natural Resources Conservation Service, this dam stands at a height of 20 feet and has a length of 565 feet. With a storage capacity of 53 acre-feet, it serves as a vital water resource for the surrounding area, providing a normal storage capacity of 34 acre-feet.

Managed by the South Dakota Department of Environment and Natural Resources, Konrad Kjerstad is regulated, permitted, inspected, and enforced to ensure its safety and compliance with state regulations. Despite being rated as having a low hazard potential and not yet assessed for its condition, this dam plays a crucial role in flood control and water management in the region. With a maximum discharge capacity of 560 cubic feet per second, Konrad Kjerstad remains a key infrastructure for water resource and climate enthusiasts to monitor and study for its impact on the local ecosystem.

While lacking detailed information on its emergency action plan and risk assessment measures, Konrad Kjerstad stands as a testament to the importance of maintaining and monitoring dams for sustainable water resource management. As a part of the St. Paul District under the US Army Corps of Engineers, this dam serves as a critical piece of infrastructure in the region, ensuring water security and environmental protection for the community. With ongoing inspections and regulatory oversight, Konrad Kjerstad continues to be a focal point for water resource and climate enthusiasts seeking to understand the intersection of human infrastructure and natural ecosystems.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
