Summary
This earth dam, completed in 1996, stands at a height of 37 feet and stretches 900 feet in length, providing a storage capacity of 434 acre-feet. Despite its low hazard potential, the dam serves an important purpose in safeguarding the surrounding area from potential flooding events.
With a moderate risk rating, Csah 5 Detention is regulated and inspected by the Minnesota Department of Natural Resources, ensuring its structural integrity and functionality over time. While it currently operates with uncontrolled spillways and outlet gates, this flood risk reduction structure has not been rated for its condition assessment. The nearby community of Milroy benefits from the protection provided by this dam, highlighting the importance of proactive water resource management in mitigating the impacts of climate change on local ecosystems and infrastructure.
As climate change continues to impact rainfall patterns and increase the frequency of extreme weather events, the role of structures like Csah 5 Detention in managing water resources becomes increasingly crucial. By monitoring and maintaining these flood risk reduction systems, local governments can better protect communities and ecosystems from the devastating effects of flooding, ensuring a more resilient future in the face of a changing climate.

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.
