2005 Willow Creek Flood
In 2005, a less-than-20- year flood set loose cribbing, waste rock and other debris down the West branch of Willow Creek from the Commodore/Nelson Tunnel area. The flood caused the destruction of a drainage channel designed to prevent the release of contaminants into West Willow Creek. These events prompted the USEPA listing of the site on the National Priorities List (NPL) in 2008.
