You have to expect flooding when you live by a RIVER

I have a little bit more sympathy for these folks than I normally would in a situation like this, because odds are this was unfathomable when they built:

The Mendenhall River drainage is extremely short, and the land is rising, such that the river has incised itself into ground, making flooding surprisingly unlikely for such a rainy place. These Suicide Basin releases only started in 2011, and prior to the first one were completely unforeseen.

Prior to 2011, a 100 yr flood was predicted to raise Mendenhall Lake to approximately 65.5 ft AMSL, and the highest recorded flood (also prior to 2011) was 61 ft AMSL. This thing jacked the whole lake up to 74.97 ft in something like 12 hours.

You can see from the footage that the house wasn't flooded, just fell in due to bank erosion. That house's foundation was probably 20 ft above the highest ever recorded crest on the river, and a good 15 ft above the 100 yr flood (prior to 2011). Pretty rotten luck, if you ask me.

Probably an ice dam breaking.
They had to come up with a scary globull warming name for it.
