What Makes Buoy 10 a Fishery You Can’t Pass Up?

Buoy 10 is one of the Pacific Northwest’s most productive salmon fisheries, where large runs of Chinook and coho funnel through the estuary each August (upwards of 1 million fish per season). When the run is on, the action speaks for itself.

The variety keeps things interesting, too. Chinook, coho, and sturgeon all in one place is a rare combination, and the shallow estuary makes sturgeon fishing especially adrenaline-inducing.

Then there’s the scenery. The Columbia River mouth is a wide-open stretch of water where the Pacific Ocean meets the Pacific Northwest’s largest river system. Clear mornings, the Coast Range at your back, birds working the surface, and fish rolling in the chop. It’s the kind of place that’s hard to describe until you’ve been out there and experienced it for yourself.

As your Portland fishing guide, our calendar is packed every summer season at Pacific Drifter Guide Service. Fishing Buoy 10 is a life-changing experience, and after one trip out here, we think you’ll feel the same way.

10 for 10: Ten Tips for Fishing Success at Buoy 10

#1: Let The Tide Lead the Way

Tide is everything at Buoy 10. If you’re not planning your day around the tides, you’re leaving fish in the water. At Pacific Drifter Guide Service, we keep a constant eye on tide charts to make sure you’re going out at prime fishing time. 

• Incoming tide (flood tide): 
  • Salt water pushes into the estuary, bringing salmon with it so they can begin their upstream migration. This movement concentrates fish in predictable transition zones. Many anglers hit Buoy 10 to grab salmon fresh from the ocean.
  • Sturgeon see incoming tides as a prime feeding window. Rising waters push forage fish and invertebrates back into the estuary, and hungry sturgeon are there waiting to chow down on their next meal.
• Outgoing tide (ebb tide):
  • When the tide begins to flow out back toward the ocean, current speeds increase and sweep baitfish along with them.  Salmon feed aggressively during this movement, holding in key zones to conserve energy before moving upstream.
  • Sturgeon are bottom feeders and tend to move to shallower feeding zones during the outgoing tide, rooting through the bottom as the current stirs up food and carries the scent of their favorite food.
• Slack tide (the transition):
  • As the current changes, salmon feed and hold in the current seams and may become less focused on their travels and more responsive to bait presentations. 
  • When the current changes, sturgeon like to hold their positions on the bottom without expending energy fighting against the flow, so they’re more likely to go after bait sitting in front of them.

#2: Hit Peak Bite Windows

Not all hours on the water are created equal at Buoy 10. Knowing when each species is most likely to bite helps you fish smarter and make the most of your time out there.

• Salmon: An hour or so before the bottom of the low tide, and then the incoming tides are favorable for salmon fishing. Also, the top of the tide and the beginning of the outgoing are great times to target salmon. 
• Sturgeon: Sturgeon aren’t as responsive to light as salmon. Since they’re bottom feeders relying mostly on scent and vibration, they’ll bite throughout the day as long as the conditions are right. That said, they’re still most active during tidal movement, so going during a tide change can give you the best luck.

#3: Match Your Gear to the Fish

Having the right setup for the right species makes a bigger difference than most anglers expect. 

• Salmon Gear: Medium-action rods, a line counter reel, and your choice of bait or spinners are simple and effective.
• Sturgeon Gear: Heavy-action rods, strong braid, and a reel built for a long fight. Sturgeon are powerful fish and will quickly expose cheap or weak gear. 
• Electronics: A fish finder and GPS are non-negotiable. The water moves, the fish move, and you need to know where to move with them.

If you don’t want to worry about any of this or spend money on expensive equipment, let us handle it. That’s exactly what we’re here for. We’ll show up with everything you need for whatever species you’re targeting.

#4: Don’t Skimp on Bait

Fresh bait isn’t just a preference at Buoy 10. The right bait can give you a competitive advantage. When you’re fishing up next to a fleet of boats, the details matter, and bait quality is one of the easiest ways to separate yourself from the pack. 

• Salmon are visual hunters, so presentation is everything. Fresh herring or anchovies are used with plastic helmets or run whole, and plug-cut herring are used. Fresh baits have better scent and better results. Poor bait presentations can easily be ignored, especially if there are better options from other boats.
• Sturgeon hunt almost entirely by smell, so scent is the whole game. Fresh smelt, shad, or sand shrimp will always outfish old freezer-burned bait. A strong scent trail is what gets them fighting after your hook.

Fish are smarter (and pickier) than people give them credit for, especially at Buoy 10, where they’ve already seen plenty of offerings from the fleet next to you. Going out with a team of experts who know what they prefer makes all the difference.

#5: Read the Water Right

Knowing where to drop your line is just as important as what’s on the end of it. Buoy 10 is a large, dynamic fishery, and the anglers who are putting fish in the boat are the ones who know how to read what the water is telling them.

• Water color: Cleaner, greener water is where salmon want to be. Murkier water can still hold fish, but when visibility is low, you should shift your focus to scent over presentation.
• Current seams: Fish stack up where fast water meets slow water. These edges are natural feeding lanes where baitfish get disoriented, and predators capitalize on this frenzy. 
• Temperature: Salmon are most active in water between 55 and 65 degrees. When temperatures climb above that range, they become sluggish and less likely to bite. Sturgeon tolerate a wider range of temperatures, but feed most aggressively in cooler water. If surface temperatures are running warm, fish deeper where the water stays cooler.

#6: Troll or Anchor With Purpose

How you fish matters just as much as where you fish. At Buoy 10, trolling and anchoring aren’t interchangeable, and knowing when to do each is one of the experienced Columbia River angler.

• Troll for salmon. Salmon are active, roaming fish that cover a lot of water, so you need to move with them. Trolling lets you put bait in front of moving fish and adjust depth as conditions change. When salmon are feeding, a well-presented troll at the right speed and depth will find them.
• Anchor for sturgeon. Sturgeon fishing is a waiting game, and anchoring is how you play it. Once you’ve found a productive hole or soft bottom area, drop fresh bait, and let the scent trail do the work. Pulling the anchor and repositioning every few minutes lowers your chances. Commit to a spot, give it time, and trust the setup.

#7: Target Structures and Travel Lanes

It may seem like fish just swim around all day, which they do, but they don’t wander randomly. Their paths and holding spots are predictable.

One of the best Buoy 10 salmon fishing tips is knowing that shipping channels and their edges are major salmon highways. Fish moving in from the ocean follow deeper water and use these travel lanes to navigate upriver. Work the edges, not just the middle.

When the bottom changes depth, fish pause. Salmon use drop-offs as staging areas, and sturgeon park themselves along the deeper side to snag up food moving with the current.

Any spot where current slows or deflects, behind a point, along a sandbar edge, or near structure, is where baitfish congregate, and predators are not far behind. These are ambush spots, and they produce consistently throughout the season.

#8: Chase Action, Not Reports

Fishing reports have their place, but at Buoy 10, conditions can flip in a matter of hours. A report from yesterday morning might as well be from last week by the time you’re on the water.

• Tides shift, bait moves, and fish follow. A school that was stacked in a channel at first light could be three miles upriver by afternoon. Water clarity can change with a single tide push. What was hot yesterday is not a guarantee of anything today.
• Watch bird activity, bait balls on the surface, and boat clusters. These are all real-time signals that fish are present. If you see birds working, something is pushing bait up from below. Get there. If boats are leaving the area in droves, there’s usually a reason.

Reading live conditions quickly and making smart decisions on the fly is a skill that takes time to develop. At Pacific Drifter Guide Service, we adjust to the water conditions in real time on every trip. We’re not relying on yesterday’s report; we’re reading today’s water and getting you fish.

#9: Know the Rules & Regulations Before You Go

Oregon’s fishing regulations are unique in that they’re constantly changing. Oregon’s Department of Fish & Wildlife actively monitors fish populations throughout the season and will adjust rules mid-season when they need to, sometimes with little notice.

Season dates, daily bag limits, retention rules, and even which species you can keep can all shift based on run counts and resource management decisions. What was legal on Monday may not be legal on Friday.

Check ODFW’s website and the MyODFW app before every trip, not just when the season opens. Regulations for Buoy 10 are updated in real time, and ignoring a mid-season change is not a defense when you’re on the water.

Even better, choose a guide who consistently stays up to date with the latest regulations to ensure you’re in compliance with the law.

#10: Stay Sharp, Stay Safe

Buoy 10 is a fun fishery, but it’s also one of the most demanding. The Columbia River mouth is a high-traffic, fast-current, open-water environment that deserves your full attention from the moment you board the boat.

Weather conditions can change fast. Fog rolls in, wind picks up, and chop builds faster than most people expect. 

Boat traffic during peak season can be one of the most congested stretches of water in Oregon. Stay aware of your surroundings, know the right-of-way rules, and give commercial vessels and larger boats plenty of room.

Some other safety tips we always recommend:

• Wear your life jacket
• File a float plan and let someone onshore know where you’re going
• Carry a VHF radio (and know how to use it)
• Keep a first aid kit and emergency signaling gear on board
• Make sure your navigation lights are working
• Don’t fish alone if you can help it
