WSDOT created the Fish Passage Barrier Removal Program in 1991. The program finds and corrects barriers that restrict or block fish access.
The U.S. District Court in 2013 issued a permanent injunction. The permanent injunction requires the state to speed up barrier correction. Chico Creek is among those included in the federal injunction.
$57.6 million is set aside for this project. This includes environmental study, design engineering, and construction.
