Engineering With Nature® initiative captures sustainability award for the Corps
In one Engineering With Nature® project located on Washington’s Skagit River, USACE Seattle District incorporated salmon habitat features into levee repairs made from 2007 to 2011. Installation of large logs with rootwads at the toe of the levee provides low-velocity refuge habitat for juvenile salmon on their migratory route to the estuary. Since installation in 2011, additional woody debris has recruited to create a longer and wider area of habitat benefits. Skagit River has been designated as a critical habitat for three salmonid species listed under the Endangered Species Act.
