BAE Systems Battelle PNNL 2 Objectives
• Characterize juvenile chinook behavior and habitat use in urbanized Lake Washington Ship Canal, Lake Union System and Shilshole Bay 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
