EA-1374-SA-03: Supplement Analysis

Avian Predation on Juvenile Salmonids in the Lower Columbia River Research Project

The Bonneville Power Administration (BPA) is funding ongoing research on Caspian terns, double-crested cormorants, and several species of gulls (glaucous-winged, western, California, and ring-billed) begun in 1996. BPA analyzed environmental impacts of the research in an Environmental Assessment (EA) completed in 2001 (DOE/EA-1374). The purpose of this Supplement Analysis (SA) is to determine if a supplemental EA is needed to analyze additional research activities proposed as part of that project.
