Flood Preparedness and Response
The National Weather Service has updated their outlook for spring flooding in the Mississippi River Basin. As always, the threat of seeing major flooding will depend on what kind of rainfall/temperature patterns we get later in March and April.
In Cottage Grove, the most at-risk neighborhoods are Grey Cloud Island and River Acres. See the maps below to see which properties in those neighborhoods could be most affected by flooding.

As of April 20 at 1 p.m., Cottage Grove Public Works has closed Grey Cloud Trail bridge and is detouring traffic through Grey Cloud Island Township. The school district transportation office has been informed of this road closure. With the addition of recent rain, a long crest is predicted by the National Weather Service, so the closure will extend into next week.
The detour route is mapped in the document below.

If flooding happens in your area, your electric and/or gas service may be disconnected to ensure the safety of your home and the people in it. You should not attempt to disconnect electricity or natural gas service yourself.
