So, to start off here are a few random pics I took while on a walk a few months back. They're not the ones I wanted but I can't find those, so these are the one's you're going to get. They're just to give you an idea as to the dimensions of the river bank and surrounding areas.
Pretty and cheery right? (Yes, that's a bride.)
So, here's today, the same general area. I can't get one that shows where the boat was as it's gone - that region is mostly underwater. The closest I can get is what was behind the boat - a little island with a playground. Click on it and you'll see you're looking at the top of a slide and the top of a swingset.
In the photo with the bride this little restaurant with the red roof is in the distant background. I was standing under the arches in the background when I took the pic of the newly married couple.
You can see some stairs that lead down - but that's just the first of three sections you take to get to the lower level.
The streetlamps aren't like sidewalk street lamps, these serve large boats that dock here so they're quite tall.
This is the top of a billboard.
Here you can see how they're keeping Kampa Island and parts of Mala Strana safe. You can't even see where the stairs down to the lower restaurant level start as they're completely underwater.
The city is pretty dry. There have been deaths but some of those are due to stupidity rather than an general threat (rafting, surfing, etc). Areas have lost power and water but it's being restored. Around the country about 7,000 have been evacuated. Other cities, towns, really, have been much harder hit than Prague has. The metro has been greatly impacted but there are supplemental buses and trams running in order to ensure the backup doesn't get too crazy. It's stopped raining for a bit - it had while I was taking the photos too - but we're expecting more... and they have to release water from a dam in order to ensure the dam doesn't break, so they expect the river to increase even more - but it's already receded a bit. Fortunately they don't expect it to get to the level of the last flood - but the city is prepared for that level of flooding, so even if it increases dramatically things should hold.
Hope you're warm and dry and having better weather than this.
