August is a great time to be fishing in Astoria. From the Mouth of the Columbia River and the famed Buoy 10 and all the way up to the Astoria Bridge you can easily catch limits of salmon in a short time. Both big fall Chinook (King) salmon and Coho (Silver) salmon are open. Both wild and hatchery born Chinook salmon are legal to keep while the Coho’s must be fin-clipped hatchery fish.
When I fish the lower Columbia River for salmon I like to troll Herring using a diver or lead to get the bait deep in the water. We usually always troll with the current so sometimes you are covering lots of river in a little time. I can tell you this when you get a strike trolling down river you will know it because they will slam the rod tip to the water. If you are looking to put some fresh Salmon in the freezer you won’t want to miss out on Buoy 10 fishing in August.
