It does'nt look that bad in the video. Are the waters down from their crest there?
In NY we got about that much flooding during Irene. The creeks and streams washed out roads and bridges deposited huge heaps of mud on side roads adjacent to them. In some places houses were undermined and fell into the waterways.
It's pretty bad around Boulder canyon. More rain today isn't going to help.
