Where in the canal...big area. North end by the bridge you can do good casting off the beach or just out of a boat in 20-30 feet of water. Buzz bombs, point Wilson darts and whole herring are best.
Mid point of the canal same type of thing, as well as some good mooching areas. Mooching is tricky and takes a lot of practice to get good. Browns Point and Hazel Pt are good... Quilecene Bay will be loaded with silvers by then, and there a bunch of pinks running down the western shorelines.
Good luck.
