I can elaborate on this: Under Bonniville to maybe about two miles down is your best bet. Around Beacon rock is really popular. Look for the deep spots and anchor above them. Backbounce your bait back into the holes. When the Shad move in the fishen gets good. May to Augest is best. All the guide boats will show you the best holes. So the first day is uasaully a learner. Catch the fresh Shad in the morning and move to the Sturgy's after you have a few baits. The launches are the Fishery on the Oregon side and Beacon rock State park on the Wash side. You will need up to 84 oz weights up here as the currents are strong. You probably already have the anchor system but unless you have the big 4 prong you probably wont hold under the dam, Youll probably be down by Beacon rock before you get a good solid anchorage. Both the Fishery and Skamania store can help with anything else...Also Braids and super lines are a must. 60 lb Mono wont cut it...Ive personally landed many of these monsters and I know It would be way to much strain on the fish if you use a light 60lb Mono! Plus they could drag you through other peoples anchors if you cant control them. Ive landed my biggest 2 years ago in Aug. 12.5 feet 550 to 600 estimated weight. It took 1.75 hours and went through all of us numeorous times. We were done after that! And it was only 1:00p.m. If ya need more dont hesitate to ask.
