Marshall Barrows

Marshall biosampling chum salmon.After receiving a B. S. in Wildlife Biology with an Aquatic Emphasis from The University of Montana in 1998, Marshall worked for the Chase Lake Prairie Project (USFWS) near Woodworth, ND. He was involved in restoring drained wetlands, conducting waterfowl surveys, native grassland evaluations, and banding ducks and white pelicans.

In 1999, Marshall worked for the Juvenile Fish Transportation Program (Army Corps of Engineers), monitoring out-migrant pacific salmonid smolts as they were transported by barge past eight mainstem dams on the Snake and Columbia Rivers.  Also in 1999, he conducted a steelhead spawning ground substrate analysis on seven tributaries to the Wind River in the Gifford Pinchot National Forest (US Forest Service) near Carson, WA.  In addition, he assisted with stream restoration activities, habitat evaluations, and snorkel surveys.

Marshall began working at the Columbia River Fisheries Program Office in 2000, where he primarily worked with a project that examined the factors limiting Columbia River Gorge chum salmon populations below Bonneville Dam.  Since 2003, Marshall’s work has been focused on monitoring migratory bull trout movement patterns and assessing habitat use in the Walla Walla River and the mainstem Columbia River.  Currently, Marshall is a member of the CRFPO’s Population and Habitat Assessment Group.  Recently, his work has focused on bull trout use of the Mainstem Columbia and Snake rivers, various bull trout habitat assessments and he also contributes to the Clackamas River Bull Trout Reintroduction Project.

Marshall, his wife, Nora, and their daughters, Cassidy and Darby, live in Vancouver where they enjoy fishing, gardening and many other recreational activities.  Marshall regularly returns to Montana to fish, hunt and watch some “Griz” football with friends and family.
