It’s been a bad few years for summer steelhead runs to areas upriver of Bonneville Dam in the Columbia and Snake River Basins. This year (2022) is expected to be the sixth consecutive year of poor runs, following last year’s record low run of just under 70,000 fish.

Last year’s run was the lowest since records began in 1938, raising alarm for wild summer steelhead and some concern regarding Snake River Basin hatcheries’ ability to meet hatchery broodstock needs. For the first time since 1978, the popular Deschutes River was closed to steelhead fishing.

Such closures lead to real economic and social costs for some Oregonians, including anglers, guides, and local communities. These stakeholders are also some of the most vocal supporters of steelhead and the need to conserve these iconic fish for future generations.

With restrictions and closures likely to continue in 2022 and beyond, ODFW fish biologists across the Columbia and Snake River Basins are more closely coordinating on regulations and management. ODFW is also seeking:

Greater public involvement in the process, so stakeholders have a more formal way to provide input.
More transparency on what management actions will be taken and when, so anglers, guides and local communities can prepare for restrictions.
Equitable sharing of necessary conservation to sustain steelhead for future generations.

Stakeholders are encouraged to sign up for this page to receive updates on steelhead runs and regulations.

About summer steelhead fisheries

Steelhead are rainbow or redband trout (O. mykiss) that migrate to the ocean during their first or second year, returning one to three years later to spawn. While in the ocean, steelhead grow significantly larger than trout who never leave fresh water. Summer-run steelhead return to freshwater between May and October and require several months to mature and spawn. Winter-run steelhead return to freshwater between November and April and spawn shortly thereafter. Coastal streams are dominated by winter-run steelhead, whereas inland steelhead of the Columbia River basin are almost exclusively summer-run steelhead.

Wild upriver summer Columbia River steelhead (those destined for areas upstream of Bonneville Dam) are protected under the Endangered Species Act (ESA) and have been listed as Threatened since the late 1990s.

Ocean conditions, predation, impacts from dams (including high water temperatures, low flows and passage difficulties), fishery impacts, degraded freshwater habitat, and hatchery production and/or practices all contribute to their Threatened status. ODFW staff and other natural resource agencies are fully engaged in addressing these factors through continued negotiation with hydropower operators via the U.S. V Oregon framework, Columbia River Biological Opinion, predator management (including sea lions and pikeminnow), habitat improvements, protections like thermal angling sanctuaries, fishery regulations, and careful hatchery fish management.

The B-Index upriver summer steelhead run is of most concern and currently the most constraining for fisheries. B-Index steelhead typically spend two years in the ocean before returning to freshwater and are defined as steelhead larger than 31 inches for management purposes. They pass Bonneville Dam beginning in August and peaking in October. While wild fish in this component primarily return to the Clearwater Basin in Idaho, B-index sized fish can return to tributaries throughout the Columbia River Basin to spawn. The A-Index run (fish smaller than 31 inches, generally one year in ocean) and Upriver Skamania Stock (primarily hatchery origin upstream of Bonneville Dam, returns to Columbia River tributaries between Bonneville Dam and the Klickitat River) are also management components in the aggregate run.

While recreational and commercial non-tribal fisheries do not directly harvest wild steelhead, some mortality occurs in all fisheries due to incidental handle and release mortality.

Due to this incidental mortality, fisheries authorized in the Columbia River and tributaries must stay within certain impacts on protected fish. Under the U.S. v Oregon Management Agreement (MA), the states are authorized to conduct fisheries occurring downstream of Hwy. 395 near Pasco, WA within an overall allowed impact of ≤4% for both wild A-Index and B-Index summer steelhead for the entire year (2% of that for the fall season).

The states of Oregon, Washington, and Idaho and the Columbia River tribes have a consistent track record of remaining within the federally approved harvest constraints (e.g., ESA impacts) that guide annual fishery management. Fisheries in the Snake River and upper Columbia River that impact upriver summer steelhead have separate ESA impact coverage and have also remained within those limits.

Regulations to protect steelhead

Since 2017 when steelhead forecasts downturned, Oregon and Washington fishery managers have implemented a number of fishery restrictions throughout the Columbia River and various tributaries to further reduce steelhead mortalities. Protective regulations have included broad area and time closures; time/area/gear considerations for commercial fisheries; one-steelhead bag limits when open; thermal angling sanctuaries to protect summer steelhead where they stage in the mid-Columbia and tributaries; and hoot-owl restrictions (closing fishing at 2 p.m. before temperatures are warmest). Collectively, these regulations have further reduced the take of ESA-listed wild fish and increased hatchery escapements.

ESA impacts will vary depending on where and when a fishery is occurring. While the Columbia River’s summer steelhead run can include populations originating from both lower and upper river systems, steelhead destined for the lower river tend to enter earlier. Lower river winter steelhead fishing targets fish which enter from November to April and do not pass above The Dalles Dam (e.g. upriver summer steelhead are generally not encountered in this fishery).

Steelhead fishing happening in the lower river in early summer (May and June) targets Skamania Stock, which is primarily hatchery origin fish that return to tributaries above and below Bonneville Dam. Beginning in July, the recreational fishery in the lower Columbia River begins to handle upriver A/B-Index summer steelhead, which have been the focus of recent concern.

Besides bag reductions, a series of rolling steelhead retention closures have been used in recent years throughout the mainstem Columbia River to limit the handle of A/B Index summer steelhead.

Impacts of fishing on upriver summer steelhead have been higher in the mid-Columbia and tributaries like the Deschutes, John Day and Umatilla rivers, where upriver summer steelhead stage before migrating to spawning areas throughout the Basin. Substantial angling effort focuses on hatchery summer steelhead, but encounter rates of wild summer steelhead can be high in these fisheries. Fishing was very restricted in this area last year as managers took drastic steps to conserve wild steelhead in these mixed stock fisheries.

Anglers further up the system (including on the Snake River in Idaho and in the Grande Ronde and Imnaha in NE Oregon) were able to target hatchery summer steelhead last year because these fisheries occur later in the year, the fish are closer to their destination, and more information on tributary-specific returns is available.

While similar restrictions are likely in 2022 and whenever there are low runs, few additional fishery-restricting actions remain available to provide additional substantive reductions in steelhead impacts. Remaining non-treaty salmon fisheries are not targeting steelhead, so closing salmon-directed fishing will not result in dramatic additional savings. For example, last year (2021), wild steelhead impacts expected to accrue from fisheries were very low and well-below ESA impact limits: Fall season: 0.59% or 161 mortalities for A-index; 1.03% or 10 mortalities for B-index.

Forecasting, season-setting to reduce impacts on upriver fish

Columbia River fisheries are likely the most intensively managed in the world. Fishery managers from both Oregon and Washington use near real-time information on not only fishery performance but also on stock abundance by closely monitoring runs via dam passage counts, long-standing collaborative creel programs, catch-sampling and fish ticket data for commercial fisheries, and other methods. Seasons are planned with consideration of preseason forecasts but managed as closely as possible to actual abundance, with the goal of completing the season having conducted fisheries that are consistent with the realized actual abundance.

Forecasts for these runs are produced annually by the U.S. v Oregon Technical Advisory Committee (TAC) Committee in February. In March, state, federal and tribal fishery managers gather to plan salmon fisheries in the “North of Falcon” process (named after the southern border of active management for Washington salmon stocks which is Oregon’s Cape Falcon). The North of Falcon process coincides with meetings of the Pacific Fishery Management Council, the federal authority responsible for setting ocean salmon seasons 3 to 200 miles off the Pacific coast. North of Falcon also functions in tandem with the Pacific Salmon Commission's Pacific Salmon Treaty agreements, which guide the conservation and management of salmon fisheries for the U.S. and Canada.

The TAC is generally able to begin updating the various upriver steelhead runs that pass Bonneville after the point where about 50 percent passage is normally expected—or around mid-June for upriver Skamania stock, mid-August for A-Index steelhead, and mid/late-September for B-Index steelhead. Over the years, the TAC has observed that forecasts attempted prior to this timeframe are far less accurate than those made later. Reviews, assessments and actions are frequent during this time period, particularly August and September, which are the most intensively managed portion of the fishing year for managers. Due to differential run timing for wild and hatchery components, predicting the sub-components of each stock is more challenging.

While summer steelhead forecasts remain poor for 2022, there are hopeful signs that conditions for salmon and steelhead may improve in the Columbia Basin in coming years. NOAA estimates that ocean conditions off Oregon in 2021 were the second-best since sampling of ecosystem indicators started in 1998. These improved conditions may result in better ocean survival and subsequent adult returns in the future.
