This project installed a dedicated lamprey passage tube at the hatchery diversion structure on Rowdy Creek — a tributary to the Smith River in Del Norte County — which had functioned as a complete barrier to Pacific lamprey at low flows. A video monitoring system was also installed to document passage events, and public educational signage developed for the hatchery visitor area. The passage facility opened an estimated 11.4 miles of upstream habitat and addresses a culturally significant species for the Tolowa Dee-ni’ Nation, who have traditionally harvested lamprey from the Smith River.
