Check out these photos from the field! Lisa K Weiland (sitting) and Leah Tai from the U.S. Fish and Wildlife Service are shown above. This project is working to learn how larval lampreys use soft substrates for burrowing.

Toby Kock (right, in plaid shirt) listens to a question during the Fish Passage Tour while standing on the North Shore Collector in the forebay of Cowlitz Falls Dam. The group discussed various ways that migrating juvenile salmon approach and pass the dam.

Participants of the Fish Passage Tour view the North Shore Collector separator at Cowlitz Falls Dam, WA. Fish are collected here to allow staff to count, determine species, and sample fish as they migrate downstream.
