Project: Sarah Creek habitat restoration Client: Cowlitz Indian Tribe Washington’s natural salmon runs are critical to the health of the Puget Sound ecosystem, as well as to the sustenance of the Cowlitz Indian Tribe. The Sarah Creek habitat enhancement is one of 10 projects that have been implemented by the tribe in the Abernathy Creek Watershed, which is part of the Lower Columbia Intensively Monitored Watershed. A unique combination of stream restoration approaches was the ultimate solution to overcome many site and regulatory barriers to transform this section of Sarah Creek from a fish barrier to nurturing fish habitat. The project included an innovative application of boulder ballast for large wood structures placed over bedrock.
