Csah 30 Detention, located in Yellow Medicine County, Minnesota, is a crucial flood risk reduction structure designed by MNDOT in 1996. This earth dam stands at a height of 17 feet and spans 300 feet in length, with a storage capacity of 115 acre-feet. The primary purpose of this detention structure is to mitigate flooding in the area, particularly along the Canby Creek-OS river or stream.

With a low hazard potential and a satisfactory condition assessment as of May 2018, Csah 30 Detention serves as a reliable defense against potential flood events in the region. Managed by the local government and regulated by the Minnesota Department of Natural Resources (MNDNR EWR), this structure plays a vital role in protecting the surrounding communities from water-related disasters. Despite being uncontrolled, the spillway and outlet gates are designed to handle a maximum discharge of 320 cubic feet per second.

As water resource and climate enthusiasts, it is essential to recognize the significance of infrastructure like Csah 30 Detention in safeguarding communities and ecosystems from the impacts of extreme weather events. By understanding the design, purpose, and functionality of such structures, we can better appreciate the efforts made to manage water resources and enhance resilience in the face of changing climate patterns.
