When most people think of searun cutthroat, they think of misty October mornings, colorful autumn leaves, and coastal rivers tumbling through forests of lush green pine. And while it’s true that fall weather brings with it the height of searun season, when fish are running upstream in dense pods in search of their natal grounds, these fish can actually be pursued throughout the entirety of Oregon’s general trout season.
In freshwater environments well upstream of any tidal influence, large searun cutthroat often become resident and remain in the river year-round. Once these fish reach a certain size, there’s no real need to return to the estuary for food. They’re big enough to prey on large crawdads and small fish. Finding these fish during the summer months, however, is a labor of love. It takes ample time on the water and a lot of exploration to find the fish you’re looking for. And don’t expect them to be in the same place from one year to the next.
You can also target sea runs in freshwater just after they spawn in the spring, as they make their way back downstream to the estuary. These fish are larger than the average cutthroat, but coming off a long winter and a labor-intensive spawn, they don’t fight with the same reckless gusto as a sea run fresh from the food-rich environments of our estuaries and bays. The window here is also short — from the time general trout season opens in late May, you might have a week or maybe three at most to effectively intercept sea runs as they head downstream.
By far the most effective and unique way to target sea runs between June and autumn’s first significant rainfall is in the estuary environments. These can be a bit intimidating to figure out as a first-timer. Walk and wade access is extremely limited and quite strenuous where you can. It’s hard on the gear, too — brackish water has a way of disintegrating boots and laces at a much faster rate. It’s a muddy business, too. That’s not to say it can’t be done, and many do. But it’s considerably easier to target these fish from a boat or watercraft.
Searun cutthroat are not like steelhead or salmon; they do not embark on some great migration in search of food with a few thousand of their friends and cousins. Their trip to the salt is about one thing only — food. They’re not interested in being small fish in a big ocean, and during the summer months these aggressive fish are the apex subsurface predators in the tidal reaches of our coastal rivers. They utilize the twice-daily influx of cold, well-oxygenated water brought in by the ocean’s tides to thrive while the upper reaches of their home rivers get low and hot.
Sea runs are ambush predators, like brook trout or bass, and the prevalent logjams and funky subsurface structure of Oregon’s tidal environments create an ideal habitat. Targeting these fish from a boat is fairly simple. You move along slowly, casting streamers in toward the bank and retrieving. We use floating and full intermediate lines with five- or six-weight rods. It’s extremely active fishing, and the rewards are usually quite visual. Most takes are within a foot of the surface and fully visible. Watching a 20-inch cutthroat dart out from beneath a cut bank to inhale your fly will get even the most even-keeled angler’s heart racing.Â
The tricky part of targeting cutthroat in the estuary is timing. Cutthroat are at their most active in low light, which means mornings are your best friend. But because our estuaries are tidally influenced, we need an incoming tide in the early morning that pushes us upstream. As a fresh-food buffet makes its way into the system with the tide, the fish activate. When the tide reverses, we fish our way back downstream, while the fish continue to feed on prey being sucked back out into the bay.
The finicky timing requirements of this fishery mean we have a fairly limited range of dates each month to effectively fish. It’s about ten days in August and ten in September, so slots fill up fast. Let us show you this unique, strange fishery firsthand and teach you how to successfully target sea runs in the estuary on your own. Book now.Â
