What You'll Find in the Okanogan River

The Okanogan River flows 80 miles from the Canadian border south to the Columbia River near Brewers, and it holds three distinct fisheries that change by season and location. The upper river (above Okanogan town) is known for steelhead in fall and winter, with fish moving through from September through March. The middle and lower sections hold walleye year-round, concentrated in deeper pools and behind the three dams that segment the river. Smallmouth bass are present throughout but most active in summer and early fall.

Access is straightforward — Highway 97 runs the length of the valley and crosses the river multiple times, and several public boat launches exist between Okanogan town and the Columbia confluence. The river is cold and fast in spring from snowmelt, moderate in summer, and clearest in fall when steelhead fishing peaks. Winter water temperatures drop into the 30s Fahrenheit, which matters if you're wading.

Key Takeaways

  • Steelhead run the upper Okanogan from September through March, with peak fishing in October and November before water temperatures drop.
  • Walleye fishing is consistent year-round in pools below the three dams (Okanogan, Enloe, and Chief Joseph), with jigging and live bait most effective.
  • Smallmouth bass are present throughout the river but concentrate in rocky areas and current breaks during summer and early fall.
  • Washington State requires a current fishing license and a Puget Sound Steelhead Endorsement to keep steelhead; check current regulations for walleye and bass limits before you fish.
  • Public boat launches at Okanogan, Tonasket, and near the Columbia confluence provide vehicle access; wade fishing is possible but the river is cold and current is strong.

Steelhead Fishing in the Upper River

The upper Okanogan above Okanogan town receives a fall and winter steelhead run that peaks in October and November. Fish enter the river in September and move upstream through December, with a smaller spring run in March and April. The best holding water is in long, deep pools with moderate current — areas where the river slows after a rapid or where a tributary enters.

Drift fishing with roe or sand shrimp is the most common method, and you'll need to cover the water methodically from the head of a pool down. Spoons and plugs work in higher water or when visibility is poor. The river is open to steelhead fishing year-round in most sections, but check the current Washington Department of Fish and Wildlife (WDFW) regulations because some reaches close seasonally and daily catch limits vary. You must have a Puget Sound Steelhead Endorsement on your license to keep any steelhead.

Water temperature is critical — steelhead bite best when the river is between 45 and 55 degrees Fahrenheit. In November and December, early morning often means the coldest, clearest water. By January, the river is often too cold for consistent fishing, though fish are still present. Spring (March through April) brings warmer water and a second opportunity, though fewer fish return in spring than fall.

Walleye Fishing Below the Dams

Three dams segment the Okanogan: Okanogan Dam near town, Enloe Dam upstream, and Chief Joseph Dam at the top. Each dam creates a pool, and walleye concentrate in these deeper, slower sections year-round. The pools behind Okanogan and Enloe dams are the most accessible and most heavily fished.

Jigging with live minnows or soft plastics is the most reliable method. Fish the deeper edges of the pools, especially near structure like rock piles or submerged logs. Early morning and evening produce better than midday. Live bait — small shiners or crawfish — fished on the bottom near current breaks also works well. Walleye are most active in spring and fall, but they bite consistently through summer and winter if you find the right depth and structure.

The pools are accessible by boat from the public launches at Okanogan and Tonasket. If you're wading, the areas immediately below each dam can be productive but are dangerous — current is strong and the riverbed is uneven. Wear a life jacket if you wade, and stay out of the main current. Check WDFW regulations for current walleye limits and size restrictions, which can change year to year.

Smallmouth Bass in Summer and Early Fall

Smallmouth bass are present throughout the Okanogan but are most reliable from June through September. They prefer rocky habitat, current breaks, and areas with fallen trees or brush. The lower river (below Okanogan town) has more suitable habitat for bass than the upper sections, and the pools behind the dams also hold fish.

Casting small crankbaits, soft plastics, and topwater lures near structure produces best. Early morning and late evening are most active, though bass will bite throughout the day in summer if you fish shaded areas or deeper pools. The river warms to 70+ degrees Fahrenheit by July, which is ideal for bass but can slow steelhead fishing if you're targeting both species.

Bass fishing requires only a standard Washington fishing license — no endorsement. Check current size and bag limits on the WDFW website, as these vary by water body and can change. The Okanogan is not known as a trophy bass river, but 12- to 16-inch fish are common, and larger fish are possible in the deeper pools.

Access Points and Boat Launches

The Okanogan River has three main public boat launches that provide vehicle access. Okanogan City Park Launch is in downtown Okanogan and provides access to the middle river and the pool below Okanogan Dam. Tonasket City Park Launch is upstream near Tonasket and accesses the upper river and the pool below Enloe Dam. A third launch near the Columbia confluence (check with local marinas for exact location and current status) provides access to the lower river.

All three launches have parking and are free or charge a small day-use fee. The river is navigable by small motorboats and drift boats, though the current is strong in spring and summer. Jet sleds are common for reaching upper sections quickly. Wade fishing is possible in many areas, but the river is cold year-round and current is strong — wear a life jacket and felt-soled waders with good grip.

Highway 97 runs the entire length of the valley and provides numerous pullouts and informal access points. Some sections cross private land, so ask permission before crossing fences. The river is public below the high-water mark, but access to the bank may require crossing private property.

Seasons and Water Conditions

Spring (March through May) brings high, cold water from snowmelt. The river is often too turbid for sight fishing, but steelhead and walleye bite well in the pools. Boat traffic increases as the season progresses. By late May, water levels drop and clarity improves.

Summer (June through August) means warm water, low flows, and clear conditions. Smallmouth bass fishing peaks, and walleye move to deeper, cooler pools. Steelhead are absent or rare. The river is most crowded in July and August, especially on weekends.

Fall (September through November) is peak season for steelhead. Water temperatures drop, clarity improves, and fish move through the river steadily. Walleye fishing remains consistent. This is the best time to visit if you want multiple species and fewer crowds than summer.

Winter (December through February) brings cold water and short days. Steelhead are present but bite is inconsistent. Walleye fishing continues but requires patience. The river rarely freezes solid, but ice can form on the banks and wading becomes dangerous.

Regulations and Licensing

You must have a current Washington State fishing license to fish the Okanogan. A Puget Sound Steelhead Endorsement is required to keep steelhead — this is separate from the base license and costs extra. Walleye and smallmouth bass require only the base license.

Catch limits and size restrictions vary by species and can change year to year. Check the current WDFW regulations before you fish — the agency publishes a detailed guide for each water body. Some sections of the river may have special rules (catch-and-release only, for example) or seasonal closures. The WDFW website has a searchable database of current rules by location.

The Okanogan is open to fishing year-round in most sections, but some tributary streams and specific reaches close seasonally to protect spawning fish. If you're fishing a tributary or an unfamiliar section, verify the current status before you go.

Frequently Asked Questions

What's the best time of year to fish the Okanogan?

Fall (September through November) is best overall — steelhead are moving through, water is clear and cool, walleye bite consistently, and crowds are smaller than summer. If you target only walleye, fishing is consistent year-round, though spring and fall are most productive.

Do I need a boat to fish the Okanogan?

No. Wade fishing is possible in many sections, especially in the pools behind the dams and in the upper river. The river is cold and current is strong, so wear a life jacket and felt-soled waders. A boat gives you access to more water and is easier for covering distance, but it's not required.

Can I keep steelhead I catch in the Okanogan?

Yes, if you have a Puget Sound Steelhead Endorsement on your license and the fish meets current size and bag limits. Check WDFW regulations before you fish — limits vary by season and can change year to year. Some sections may be catch-and-release only.

What's the closest town with lodging and supplies?

Okanogan is the main hub, with hotels, restaurants, and tackle shops. Tonasket is smaller but also has lodging and basic supplies. Both towns are on Highway 97 and are within an hour of the Columbia River confluence.

Is the Okanogan River good for beginners?

Walleye fishing in the pools below the dams is beginner-friendly — jigging with live bait is straightforward and productive. Steelhead fishing requires more technique and patience. Smallmouth bass fishing is accessible if you have basic casting skills. Start in the pools near the public launches where you can fish from shore or a boat without navigating fast current.
