Summary
This earth-type dam stands at a height of 24 feet and stretches 753 feet in length, with a storage capacity of 192 acre-feet. While the dam is primarily used for flood control and water storage purposes, it is also regulated by the South Dakota Department of Environment and Natural Resources to ensure its safety and compliance with state guidelines.
Despite being classified as having a low hazard potential and not being rated for its condition assessment, Ogren Dam plays a crucial role in managing the water resources of the area. With a maximum discharge capacity of 640 cubic feet per second and the ability to store up to 135 acre-feet of water under normal conditions, the dam serves as a key infrastructure in protecting communities from potential flooding events. Additionally, the dam's location within the St. Paul District adds to its significance in the overall water management system of the region.
As climate change continues to impact water resources and weather patterns, structures like Ogren Dam become even more essential in safeguarding against extreme conditions. With its regulated state jurisdiction, inspection, and enforcement processes in place, Ogren Dam stands as a testament to the ongoing efforts to manage and protect our water resources for the future.

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.
