Ah my story isn't that interesting but I'll tell it anyway.
When I was growing up, I lived in a town surrounding a river. Maybe about 5,000 residents. Every year when it rained, the river would rise and threaten to flood the town, nobody took the flash flood warnings too seriously. It wasn't going to flood more than their basements and backyards. Until one year, it did.
I think it was 2008? I was coming back from a scout trip in the next state over and to our surprise everything was flooded. I lived on a hill on the third floor of an apartment so we were actually able to go home safetly.
It had rained nearly everyday for a week or two, and the river had risen over the streets and rushed into the town, which generally sat at a lower level. When I walked down the street, I could see two story houses submerged to their second floors. The brown water seemed to go on forever, but I was probably just short. I saw people in boats, one family with their dog in tow, padling back over here.
I don't think anyone died, I would've remembered. The problem is that many of the houses had been destroyed, and people had to find somewhere to live. The river was also quite polluted then, so if you went in it, you could get sick. I heard they cleaned it up, though, so maybe that's changed.
The renovations continued for years, until we moved to the city. I can't find the news report anywhere online or I'd link it. I guess nobody bothered to care too much about some random town's flood.
