This document summarizes a study on Pacific lamprey in the Willamette River basin. It discusses the project objectives of determining lamprey migration patterns, overwintering locations, and use of tributaries for spawning. It provides data on the number of lamprey tagged from 2008-2012 and the number of fixed monitoring sites. It also lists additional future study objectives such as determining if lamprey spawn in the mainstem river, quantifying juvenile rearing habitat, and incorporating lamprey needs into floodplain restoration.
