Columbia River transitions to summer Chinook as high flows persist

What's Biting

What's Next

With the Columbia running at 208,000 cfs, the river is carrying substantial volume into this mid-June period. Elevated flows push fish tighter to the banks, back eddies, and slower water on inside bends where salmon can hold without burning energy against the main current. Anglers targeting Chinook in these conditions generally do best anchoring or back-trolling in the 20-to-40-foot depth range, working spinners and herring rigs through productive inside seams rather than fighting the central channel.

The new moon on June 14 sets up a solunar window worth planning around. In the lower and mid-Columbia, new moon phases tend to increase tidal exchange and bottom-current activity, nudging white sturgeon into more active feeding postures. The first few hours after a tide change, paired with low-light periods at dawn and dusk, typically produces the best action near structure. If you can get on the water during early-morning windows this weekend, the new moon timing lines up favorably.

Summer Chinook, the so-called summer run, typically begin showing in meaningful numbers by mid-to-late June. If current flow trends hold and water temps stay in the low 60s, expect the front edge of that run to become more accessible over the next 7-to-10 days. These fish tend to move more aggressively through the water column than springers and often respond well to trolled plugs or side-drifted cured roe as they stage below the dams.

For white sturgeon, the combination of high water and new moon is worth a dedicated trip. Sturgeon feed best in heavy current seams near the bottom, and elevated flow concentrates food naturally. Smelt, sand shrimp, and lamprey are reliable baits at this time of year; targeting 25-to-60-foot holes below tailouts and in main-channel bends gives the best odds. Check Oregon Department of Fish and Wildlife regulations before heading out, as retention rules for both Chinook and sturgeon on the Columbia mainstem are typically subject to in-season adjustment.

Context

For the Columbia River at mid-June, a flow reading in the 200,000-plus cfs range runs on the higher end of what this reach typically sees at this calendar date. During drier years, the mainstem often settles into the 100,000-to-150,000 cfs band by now, making fish more concentrated and predictable in their holding locations. The higher current volume this year means fish are likely distributed across a wider cross-section and can be harder to pattern from one tide cycle to the next.

The spring Chinook fishery on the lower and mid-Columbia typically peaks in April and May, with harvest opportunity narrowing through June as those fish push further upriver toward their natal streams. By mid-June, most of the springer window is behind us on the mainstem, and the season shifts to summer-run Chinook, which historically arrive in fishable numbers in late June through July.

Water temperatures at 62°F are holding in a favorable band. Columbia salmon begin to show stress when temps climb above 65°F for extended periods, and steelhead are more sensitive still. A prolonged warm spell in late July could trigger flow-adjusted restrictions on some tributaries, though the mainstem Columbia's thermal mass buffers against rapid swings.

None of the angler-intel feeds consulted for this cycle provided direct Columbia River salmon or sturgeon reports, so a first-hand comparison of how this year stacks up against recent seasons is not available from cited sources. The gauge data from USGS 14105700 is the strongest signal in hand, and it paints a river in active spring-to-summer transition, which aligns with what anglers on this system typically see in the second week of June.
