Indystorm Posted May 20, 2020 Share Posted May 20, 2020 I read that the main plant of Dow Chemical in Midland MI has activated its emergency operations center. Do not know how close it is to the river or expected area of flooding. Link to comment Share on other sites More sharing options...

chances14 Posted May 20, 2020 Share Posted May 20, 2020 Midland flood map https://cityofmidlandmi.maps.arcgis.com/apps/webappviewer/index.html?id=dce957dc48df43929d8afccbf47edd6a I guess silver lining is the major population centers should be somewhat spared. Still absolutely devastating though 1 Link to comment Share on other sites More sharing options...
OrdIowPitMsp Posted May 20, 2020 Share Posted May 20, 2020 Wow historic event happening in Michigan. That Dow chemical plant worries me. I’m sure they have a floodwall and emergency plan in place but dam failure is certainly the worst case scenario. Hope contaminates can be contained onsite. 1 Link to comment Share on other sites More sharing options...

It was built in the 1920's, it should have been updated but I doubt anything else would have held up against this flood. The only thing I can think of is the dams were far too small for the amount of water the Tittibawassee drains. After 4-7 inches of rain over the entire basin, there would be no way for the tiny spillways to let out water at a faster rate than was incoming. Why didn't they nearly drain the lakes before the event? It was always supposed to be a very large rain event - but not THIS big or pervasive. 1 Link to comment Share on other sites More sharing options...

Issue is that it sounds like normal year to year maintenance was lacking recently which is dangerous with an old earthen dam like that. They also own the Sanford Dam and its the same situation there. 1 Link to comment Share on other sites More sharing options...

chances14 Posted May 20, 2020 Share Posted May 20, 2020 Quote Water levels were still rising in Midland as of 1 p.m. Wednesday. Midland City Manager Brad Kaye said the Sanford Dam is about 60% to 80% overtopped, meaning water is flowing over the structure. Authorities aren't sure about the dam's condition because so much of it is underwater. Aerial crews are flying overhead regularly to determine how much of the Sanford Dam remains intact. Kaye said the flooding situation in Midland could worsen significantly if the Sanford Dam fails entirely. That would send a much higher surge of water into the city. https://www.abc12.com/content/news/Whitmer-working-with-FEMA-on-federal-aid-for-Midland-investigating-dam-failures-570629521.html Link to comment Share on other sites More sharing options...

It also was being neglected with the water level and not much thought was put to draining until it was too late. 1 Link to comment Share on other sites More sharing options...

This was a well advertised storm. Link to comment Share on other sites More sharing options...

This was a well advertised storm. More crumbling MI infrastructure. A century of growth followed by decades of decline. A ton of stuff was built without thought of what it might cost to maintain or restore when it reached it's life expectancy. Link to comment Share on other sites More sharing options...
