i'm nowhere near a river. people in Boulder county got flooded out that werent even near the river. sewer mains filled up and took out entire blocks of neighborhoods, houses that wernt even in the flood plains or river basins. people in drake, glen haven, hygene, pinewood, lyons, and jamestown have been through this before and all the old timers knew this was coming. build on the river and down in narrow canyons, and you will lose everything. but some people werent even anywhere near the rivers.
also, all the natural flowing undamed rivers had minor flooding at best. i would still live up poudre canyon anyday of my life, but all the damned (pun intended) rivers are trouble and will continue to cause problems as long as we choose to fight nature and hold back all that water. just like the 76 flood, hwy 34 and the big thompson watershed were the hardest hit areas. cuz us humans keep fuking with the natural order of things. rivers flood naturally, but a 20ft wall of water rushing down lefthand canyon are not nature, they are man made dams that breached.
they say its a 1000 year event, i'm willing to bet it will happen again in 30 or 40 years.
