I'm in Midland (north) as well. Drove through Sanford last night. Unbelievable devastation. Houses completely gone, many shoved off their foundations. Folks in the town are not exactly well off to begin with and most lost everything. Flood insurance it tough to get to begin with and I suspect most people were under-insured if insured at all.
I started in Albright Shores on Wednesday afternoon and worked my way down the east side of the lakes. Looking at what used to be Wixom Lake reduced to a not much more than a stream is something to see. I question whether anyone will be able to re-engineer the Edenville Dam to modern standards, get the required permits to reconstruct it, and be able to fund the project. Sanford looks like a straightforward repair process, but that's questionable as well.
