What the Lewis and Clark River offers anglers

The Lewis and Clark River is a small, clear coastal stream in northwestern Oregon that holds cutthroat trout and coho salmon. It drains into the Skipanon River near Warrenton, about 10 miles south of Astoria. The river itself is roughly 15 miles long and rarely more than 40 feet wide, making it manageable for wading and small-boat access. Most of the productive water lies in the lower half, where tidal influence reaches several miles upstream and creates holding pools for both resident and migratory fish.

The Lewis and Clark is not a destination river for most anglers — it lacks the size and reputation of the Rogue or Umpqua — but it rewards local knowledge and off-season timing. Winter steelhead pass through, though in modest numbers. The real draw is fall coho, which stack up in the lower pools from September through November when conditions are right. Cutthroat fishing is steady year-round in the upper reaches, where the river narrows and current picks up.

Key Takeaways

  • Fall coho arrive in September and concentrate in the lower river pools through November, with peak fishing typically in October.
  • Cutthroat trout are present year-round in the upper river, especially in pocket water and behind woody debris.
  • Winter steelhead move through from December to February, but runs are smaller than on larger coastal rivers.
  • Most access is from the Warrenton area via boat ramps and road crossings; wading is possible but the river bottom is slick and current can be swift.
  • Oregon Department of Fish and Wildlife regulations require a current fishing license and set specific season dates and bag limits that change annually.

Seasons and what fish are present when

Fall coho salmon are the signature fishery. They enter the river in early September and remain through November, with the heaviest concentration usually in mid-October. Coho average 8 to 12 pounds and will take spinners, spoons, and small plugs. The lower river from the Skipanon confluence upstream about 3 miles holds most of the fish; they stage in deeper pools before moving further upstream to spawn. Water level and clarity matter — coho bite best when the river is dropping after a rain and visibility is 2 to 3 feet.

Cutthroat trout are present year-round and are the most reliable catch. They range from 8 to 14 inches in the main river, with occasional fish to 16 inches in less-pressured sections. Spring (March to May) and fall (September to October) are most productive, though summer fishing is possible in the upper reaches where cooler water holds fish. Small spinners, spoons, and dry flies all work; cutthroat in small rivers are aggressive but not selective.

Winter steelhead arrive in December and run through February, but the Lewis and Clark receives only a fraction of the steelhead that enter larger coastal systems. Runs vary year to year. When they do show, they concentrate in the lower pools and respond to drift fishing with roe or sand shrimp, or to small plugs and spinners. Check current ODFW regulations before targeting steelhead, as seasons and bag limits shift annually.

Access points and how to reach them

The primary access is from Warrenton, where the river is closest to Highway 101. The Warrenton boat ramp provides the easiest entry for small boats and drift boats; it sits on the Skipanon River just below the Lewis and Clark confluence. From there, you can motor or row upstream into the Lewis and Clark. The ramp has parking and is open year-round, though winter storms can make the Skipanon rough and dangerous for small craft.

Road access exists at several points along Highway 101 as it parallels the river. Turnouts and informal pull-offs allow wading access to the upper river, particularly between Warrenton and the small community of Olney. These sections are shallower and faster than the lower pools, making them better for cutthroat than for coho. Parking is limited and sometimes unclear; scout the area before you plan to fish.

Private land borders much of the river. Always ask permission before crossing property to reach the water. Some local landowners allow access informally; others do not. Respect posted signs and closed gates. The river is small enough that word travels, and access can be lost if anglers trespass or leave gates open.

Regulations and licensing requirements

Oregon requires a current fishing license for anyone 14 and older. Licenses are available online through the Oregon Department of Fish and Wildlife website, at sporting goods stores, and at some gas stations. A one-day license costs less than a full-year license and is useful if you are visiting from out of state.

Coho and steelhead seasons, bag limits, and size restrictions change annually and sometimes mid-season. ODFW publishes a detailed Oregon Sport Fishing Regulations pamphlet each year; the Lewis and Clark falls under the Northwest Zone regulations. Before you fish, check the current rules for the specific species and dates. Cutthroat regulations are generally more open, but minimums and daily limits still apply.

Barbless hooks are required for catch-and-release fishing in some areas and seasons. Check the regulations for the specific water you plan to fish. Bait restrictions also vary — some sections allow only artificial lures, while others permit bait. The regulations pamphlet spells this out by river section.

Gear and tactics that work

For coho, a 6- to 7-foot medium-action spinning rod with 10- to 12-pound line is standard. Spoons in silver or gold (1/4 to 3/8 ounce) are reliable; small spinners like Mepps or Panther Martins also produce. Some anglers use small plugs (2 to 3 inches) cast and retrieved slowly near the bottom. Drift fishing with roe in a mesh bag works when the river is high and visibility is poor. Fish the deeper pools and behind large rocks where current breaks.

Cutthroat respond to the same small spoons and spinners, but also to dry flies and small nymphs if you have a fly rod. A 5-weight fly rod is ideal for the narrow upper river. Cutthroat are not leader-shy; 4X to 5X tippet is fine. Fish pocket water, behind logs, and in the slower water along the banks. They often hold in water only 2 to 3 feet deep.

Steelhead require heavier tackle and patience. A 7- to 8-foot rod with 12- to 15-pound line allows you to hold bottom in current and feel strikes. Drift roe in a mesh bag, or use sand shrimp under a float. Some anglers swing small plugs or spoons. Steelhead fishing is slower than coho fishing; expect to cover a lot of water and fish for hours between takes.

Water conditions and timing your visit

The Lewis and Clark responds quickly to rain. A heavy storm can raise the river 2 to 3 feet in a few hours, turning the water from clear to tan or brown. Coho and steelhead bite best when the river is dropping from a rise and clarity is returning — typically 24 to 48 hours after rain stops. Cutthroat will bite in higher, dirtier water, but visibility of 2 feet or better is ideal.

Tidal influence reaches several miles up the river, so water level fluctuates with ocean tides as well as rainfall. Low tide in the lower sections can expose gravel bars and make wading easier, but it also concentrates fish in deeper pools. High tide pushes water upstream and can slow fishing. Check tide tables if you are planning a trip to the lower river.

Fall is the most reliable season. October typically offers the best combination of coho presence, stable water levels, and comfortable weather. Winter brings steelhead but also storms, high water, and cold. Spring cutthroat fishing can be excellent, but the river is often high from snowmelt and rain. Summer is warm and clear but slow for all species except cutthroat in the upper reaches.

Nearby rivers and alternative options

If the Lewis and Clark is not fishing well or access is limited, the Skipanon River is just downstream and offers similar species and seasons. The Skipanon is slightly larger and receives more pressure, but it also holds more fish. The Nehalem River, about 20 miles south, is a larger coastal stream with stronger runs of coho and steelhead and more developed access.

The Tillamook Bay system — which includes the Tillamook, Kilchis, Wilson, and Tillamook rivers — is 30 miles south and offers more water and better infrastructure. These rivers are more crowded but more reliable for coho and steelhead. If you want to stay in the Astoria area but explore options, the Youngs River (a tributary of the Skipanon) is small and lightly fished.

Frequently Asked Questions

Do I need a boat to fish the Lewis and Clark?

No. Wading access is available from road pullouts along Highway 101, especially in the upper river. A boat gives you access to the lower pools where coho concentrate, but it is not required. Many anglers wade the upper sections for cutthroat and do well without ever launching a boat.

What is the best time to catch coho on the Lewis and Clark?

October is typically the peak month. Coho arrive in early September and remain through November, but mid-October usually offers the heaviest concentration and the most reliable fishing. Fish the lower pools, especially after the river has dropped from a recent rain.

Are there steelhead in the Lewis and Clark?

Yes, but in smaller numbers than on larger coastal rivers. Winter steelhead run from December through February. Runs vary year to year, and some seasons are better than others. Check current ODFW reports before planning a steelhead trip.

Can I fish for cutthroat year-round?

Cutthroat are present year-round, but spring and fall are most productive. Summer fishing is possible in the upper, cooler sections. Check current ODFW regulations for any seasonal closures or restrictions in specific areas.

What should I do if I see posted land?

Respect the signs and do not cross. The Lewis and Clark has limited public access, and trespassing can close off areas for all anglers. Stick to road pullouts and the boat ramp, or ask local landowners for permission before fishing their property.
