Best Fishing in Oregon

Fishing the Santiam River system

The Santiam River system in Oregon’s mid-Willamette Valley offers a pleasant variety of salmon, steelhead and trout fishing options, especially during the spring and summer months.

The Santiam is most often fished in its two main forks, known as the North and South Forks, especially for salmon and steelhead runs below the reservoirs. A modest number of salmon and steelhead are landed in the mainstem, but this section is short, has somewhat limited access, and migrating fish pass through quickly. At the other end of the system, a good bit of the trout fishing is higher in the Cascade Mountains above the reservoirs.

The North Fork east of Salem feeds Detroit Lake and flows through towns including Mill City and Stayton.

The South Fork and Middle Fork and their tributaries east of Albany and Corvallis fill Green Peter Reservoir and Foster Reservoir before flowing through towns such as Sweet Home and Lebanon. The forks join into the mainstem just south of the town of Jefferson not far east of Interstate 5, for a relatively short trek to the Willamette River.

This article discusses the major fishing opportunities within the Santiam River system and provides links to more detailed articles about some of those fisheries.

Salmon Fishing

When we talk about salmon here, we’re mostly talking about hatchery-produced spring Chinook salmon, which are released as smolts to migrate to the ocean and then return as adults that are usually over 10 pounds and sometimes over 20 pounds.

These hard-fighting, unbelievably tasty fish start showing up in April, and catches build nicely to a peak in May or June and often continue strong for at least part of July. Catches tend to drop off in August.

Both forks can offer excellent spring Chinook fishing when the runs are strong. The South Fork has the hatchery had some huge runs some years back, but there are years when the North Fork is the more productive choice.

For more details, including some specific spots to try, read our Willamette Valley Spring Chinook Salmon Fishing article.

The Santiam system also has some open seasons for fall runs of coho salmon and hatchery Chinook, but neither produces catches good enough for us to recommend fishing here, although the coho run could produce an occasional exciting day. Still, better to check out Best Coho Salmon Fishing Near Portland for information about catching silvers in the Willamette Valley and nearby rivers. For fall Chinook, we recommend Oregon’s coastal bays and rivers or the Columbia River. Start your search on our Oregon Salmon Fishing index page.

Steelhead Fishing

Like spring Chinook, summer steelhead are a big draw in the Santiam system and overlap the salmon fishing. These also are reared to smolts in a hatchery before being released in both forks to migrate to the ocean and return as much larger fish.

Summer steelhead are often in the 5- to 15-pound range, with a rare fish even larger. They are excellent fighters, often leaping while trying to shake a hook, and also a very good to eat. The Santiam system is included in a generous three-hatchery steelhead limit in the upper Willamette River system.

Unlike Chinook, summer steelhead can live for many, many months in fresh water. Still, most of them will be caught soon after their arrival. The first fish will be seen in April, but later in May, June and July are often among the best months, especially in the upper areas below the dams, where the water is coolest. With summer steelhead, the catches continue into fall; in fact, sometimes fishing for summers is very good in about October, when most anglers are focused on catching fall salmon somewhere else.

Note that fishing for hatchery steelhead is open year-round in the primary sections and in the Little North Fork (where a few will stray). At this writing, ODFW also allows the harvest of wild steelhead during the months of July and August. We recommend using the links in the Resources section to study up on regulations before fishing.

We have more about this fishery, including good spots to try on both forks, in our Willamette Valley Summer Steelhead Fishing article.

Winter steelhead also call the Santiam River system home in pretty good numbers. However, unlike the summer run, this is primarily a wild run of steelhead. Any steelhead without a clipped and healed-over adipose fin is considered wild and must be released unharmed, but they are a thrill to catch. And there are enough hatchery steelhead straying into the river system from other places to pose the possibility of catching a keeper here, although typically fewer than 100 keepers are landed in either fork or the mainstem during a season.

Both the North Santiam and South Santiam forks will produce native winter steelhead and the occasional hatchery stray. The Little North Fork also is an option. The best , typically in late winter through spring. In fact, the majority of winter fish are caught in the spring, when most anglers on this river are starting to key in on newly arriving spring Chinook salmon and summer steelhead (or fishing for trout).

Trout Fishing

There are lots of places to fish for trout in the Santiam River system.

While much of the system is managed primarily for wild trout, several upper tributaries are stocked with hatchery rainbow trout and offer outstanding catch-and-keep fishing.

One area with planted trout is the North Fork Santiam above Detroit Lake. This is a fast-moving, gin-clear trout stream tumbling out of the high Cascades. The Oregon Department of Fish and Wildlife stocking trucks make weekly stops here during the season, typically from late May into about early August.

The upper river here is followed closely by Highway 22, with turnouts that offer stream access.

The primary area stocked is from Marion Forks downriver to Detroit Lake. Some of the areas that have been regularly stocked before include Idanha Bridge, Cooper’s Ridge Road, Riverside Campground, Straight Creek Road Bridge and Downing Creek.

Bait, lure and fly fishing techniques will catch these hatchery planters.

Two other tributary streams within the Santiam River system are currently also seasonally planted with hatchery rainbow trout and offer very good opportunities to bring trout home for dinner. See our separate articles on the Breitenbush River (North Santiam tributary) and Quartzville Creek (Middle Santiam tributary).

The forks above the reservoirs and many of the tributaries that are open to angling boast pretty good populations of native cutthroat and some wild rainbow trout. In some areas, wild trout can be harvested, while in others they are strictly catch-and-release. Also note that the use of bait is allowed in some areas but not in others. The best plan is always to closely read the regulations, which are in linked in the Resources section at the bottom of this article.

Some noteworthy areas to think about for wild trout in the Santiam system include the fishery below the dams on the North Fork, which is primarily fished for wild rainbow and cutthroat trout. Fin-clipped trout may be retained here, but since trout aren’t actually stocked in this section, hatchery fish here are likely to be steelhead smolts that haven’t migrated out of the river. The South Fork above Foster Reservoir has a good population of native cutthroat trout that may be fished catch-and-release. Both sections are popular with fly anglers, but there also are plenty of other waters for trout anglers to explore within this river system that get fairly little angling pressure compared to areas that are stocked.

Brook trout, an invasive species, have colonized some areas within the Santiam system, including the North Fork above Detroit Lake. These fish are most often found in high-mountain streams and lakes, preferring the coldest and clearest water. Brook trout can be kept in any size or number in much of Oregon, but always check regulations to be sure. And while you’re at it, make sure you know the differences between brook trout and protected native bull trout (ODFW has a comparison in its regulations).

Smallmouth Bass

This is another invasive species, but they are good fighters and fun to catch. In the Santiam River system, where this is a minor fishery, smallmouth bass are found in the lower mainstem and in the lowest several miles of the South Santiam.

Smallmouths will hit soft plastic and crank bait lures, or simply a drifted nightcrawler. Look for them behind rocks or other structure or in places where they can get out of the swift current and ambush prey.
