BAE Systems Battelle PNNL 2 Objectives

• Characterize juvenile chinook behavior and habitat use in urbanized Lake Washington Ship Canal, System and nearshore marine areas • Determine residence time in selected areas of the Ship Canal: Montlake to Fremont; Fremont Cut to the Locks; Locks passage time to inner Shilshole Bay

BAE Systems Battelle PNNL 3 Objectives (cont.)

• Determine pathway selection as smolts migrate through the Locks • Estimate survival from release points to the Locks for groups released at either Montlake or Fremont
