The 2013 Colorado Floods


Floods are acts of God, but flood losses are largely acts of man.

-- Gilbert F. White

In September 2013, Colorado experienced unprecedented rainfall and massive, widespread flooding across the northern portion of the state.

This site is the Natural Hazards Center's revised version of the Gilbert White Boulder Creek Flood Notebook. The site contains contributions from leading scholars as well as practicioners involved with the response and preparation to the flood event.

Make sure to also look at BoCo Strong, Boulder County's Flood 2013 page, and The Daily Camera's One Year Stronger coverage of the floods for more information and first-hand accounts on the floods.

The recovery from the floods is ongoing, and as such so is this site. It will be updated with new essays, new media, and more information, so check back often. If you would like to contribute information or feedback, please contact us at or find us on Twitter and Facebook.
