Summary
Constructed in 1952, this earth dam stands at a height of 27 feet with a length of 1160 feet, providing storage capacity of 81 acre-feet. Managed and regulated by the South Dakota Department of Environment and Natural Resources (DENR), Robert Kressly is subject to state jurisdiction, permitting, inspection, and enforcement measures to ensure its safety and compliance with regulations.
Despite being classified as having a low hazard potential and not yet rated for its condition assessment, Robert Kressly serves as a vital structure for water resource management in the region. With a maximum discharge capacity of 9000 cubic feet per second, this dam plays a crucial role in flood control and water storage, contributing to the overall resilience of the local ecosystem and communities. As a designated state-regulated facility, Robert Kressly represents a key component of South Dakota's water infrastructure, highlighting the importance of sustainable management practices in the face of changing climate patterns and water resource challenges.
Managed by the Natural Resources Conservation Service and situated within the St. Paul District of the US Army Corps of Engineers, Robert Kressly stands as a testament to the collaborative efforts in safeguarding water resources in South Dakota. As climate enthusiasts and water resource advocates continue to monitor and address the impacts of climate change on water availability and quality, structures like Robert Kressly play a critical role in ensuring long-term water security for both human and ecological needs. With ongoing regulatory oversight and potential modifications to enhance its safety and effectiveness, Robert Kressly remains a significant asset for water management in the region.

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.
