Summary
Completed in 1995, this earth dam stands at a height of 17 feet and has a storage capacity of 153 acre-feet, providing essential water storage for irrigation and other purposes. The dam is situated on the tributary of Spring Creek, within the St. Paul District of the US Army Corps of Engineers.
Despite its low hazard potential, Dohn Dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring its safety and compliance with state guidelines. While the dam's condition is currently not rated, regular inspections and enforcement measures are in place to mitigate any potential risks. The dam's moderate risk assessment highlights the importance of continued monitoring and management to ensure the safety and longevity of this vital water infrastructure.
Overall, Dohn Dam is a significant component of the water management system in McPherson County, providing essential water storage and flood control capabilities. With its relatively low hazard potential and moderate risk assessment, the dam represents a key asset for the community and underscores the importance of responsible water resource management in the face of changing climate conditions.

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.
