Livermore and Staff – USAE Locks 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 BAE Systems Battelle PNNL 4 Study Sites Shilshole Bay Fremont Cut Locks BAE Systems Battelle PNNL 5 Fremont Cut Array King County Metro Dock 2 1 4 3 BAE Systems Battelle PNNL 6 Locks Array 6 5 3 1 7 8 4 2 BAE Systems Battelle PNNL 7 Error Estimation Depth 10 ft Depth 2 ft Horizontal Horizontal Vertical Vertical Geometric Geometric 0 5 10 15 20 Dilution of Precision (ft) BAE Systems Battelle PNNL 8 Shilshole Array Ray’s Boathouse 4 Dock 3 1 2 BAE Systems Battelle PNNL 9 Hydrophone Deployment Hydrophone BAE Systems Battelle PNNL 10 Hydrophone Deployment BAE Systems Battelle PNNL 11 Tagging and Release Release # Tagged # Released Release Release Group Chinook Coho Chinook Coho Date Loc. 1 8 9 1 2 6-Jun Fremont Br. 2 14 8 2 7 13-Jun Fremont Br. 3 8 0 6 0 23-Jun Fremont Cut Total 30 17 9 9 BAE Systems Battelle PNNL 12 Results – Residence Times Residence Time or Time within Array (hr) Site Species N Mean Max StDev Fremont Chinook 9 5.1 14 3.9 Coho 5 2.0 4 1.4 Locks Chinook 7 21.9 92 31.2 Coho 4 24.0 47 16.4 Shilshole Chinook 5 5.6 14 5.2 Coho 3 1.7 3 1.2 BAE Systems Battelle PNNL 13 Lateral Distribution - Fremont BAE Systems Battelle PNNL 14 Locks – Chinook Positions BAE Systems Battelle PNNL 15 Locks – 3D Chinook Positions BAE Systems Battelle PNNL 16 Locks – Mean Elevations (Chinook) BAE Systems Battelle PNNL 17 Locks – Vertical Dist.
