A Pacific lamprey dipped out of the Eel River in Van Arsdale Fisheries Station

A Pacific lamprey dipped out of the Eel River in Van Arsdale Fisheries Station in Potter Valley, California. "The Eel River is named after lampreys and I think it is pretty cool that we have had a two-year success of giant runs of the river’s namesake,” said Scott Harris, fisheries biologist for CDFW.
