Strait of Georgia/Puget Lowland

Chinook salmon are back in the lower Sammamish River. Over the past four weeks they have been seen along the slow, dredged reach that runs from Kenmore through Bothell toward Woodinville, with a scattering of other sightings toward Edmonds and across the Sound on the Kitsap side. These are adults on the last leg of a trip that began in the North Pacific and passed through the Ballard Locks sometime this summer.The Chinook (Oncorhynchus tshawytscha) is the largest of the Pacific salmon and the easiest to name with the fish in hand: black gums along the lower jaw where a coho's are white, and small dark spots across both lobes of the tail rather than just the upper one. In salt water they are silver with a blue-green back. By the time they reach a river like this one they are darkening to bronze and olive, the males growing the hooked snout and heavy teeth they will use to fight for position on the gravel. Lake Washington fish typically run ten to twenty-five pounds, three to five years old.What they are doing right now is mostly waiting. Adults enter Lake Washington through the locks from June into September and hold in the lake's cooler depths, then push up the Sammamish toward Bear Creek, Cottage Lake Creek and Issaquah Creek to spawn from mid-September into November. The Sammamish is the bottleneck. It was straightened and dredged in the 1960s, runs shallow and slow through open valley floor, and is one of the warmest salmon rivers in the region in late summer. Fish moving through it in August and early September are traveling in water that regularly sits near the twenty-degree mark where migrating salmon start to burn energy they cannot spare. Cooler nights and the first fall rains are what open the door upstream.Snohomish County's dry spell, described here two weeks ago, has not let up; a little over half the county has sat in moderate drought since the third week of August, and the past month at Paine Field ran about 2.7 degrees above normal for daily highs. Those numbers describe the air and the land, not the river, and no current gauge reading on the Sammamish was available to say how the water itself is running. The fish are in it regardless.Once they spawn, Chinook do the thing no other family of fish does at this scale: they die on the gravel and stay. A single carcass feeds bears, otters, eagles, gulls, dippers and the insects the next generation of fry will eat; the nitrogen from an ocean life ends up in streamside alders and cedars. The eggs overwinter in the gravel, the fry emerge in late winter, and most of this run's young will spend only a few months in fresh water before dropping down through the lake and out the locks, small enough to fit in a palm.Puget Sound Chinook have been listed as threatened under the Endangered Species Act since 1999, and the Lake Washington run is among the more heavily worked-on in the region. Adopt A Stream Foundation does its stream restoration from North Creek in Everett, a tributary that meets the Sammamish at Bothell, right in the stretch where these fish were seen.Anyone who wants to watch the run can do it without waders. The fish ladder windows at the Ballard Locks show Chinook passing into the lake through September, and by early October they will be on the gravel in Bear Creek and Issaquah Creek, where a footbridge is all the equipment needed.

Snohomish County has gone from essentially drought-free to fully dry in a single summer. As of late April, no part of the county registered even the lowest tier of the U.S. Drought Monitor's dryness scale. By the first two weeks of August, that lowest category, Abnormally Dry, covered the entire county wall to wall.A smaller slice, about 2.6 percent of the county's land area, tells a sharper story. That pocket first crossed into Moderate Drought in mid-July and has now held at or above that threshold for a full month straight, without tipping further into Severe Drought. This is a sustained trend tracked week over week on a consistent measure, not a one-off reading, which makes the month-long persistence more meaningful than the raw percentage suggests.The dryness lines up with what's been showing up on the ground all season in the Central Puget Lowland: vine maples were already coloring by mid-July, bunchberry fruited three weeks ahead of schedule, and goldenrod bloomed a full six weeks early. None of these phenology shifts can be attributed to drought specifically without more direct evidence, but a hot, moisture-starved summer is exactly the kind of stress that pushes plants toward early senescence and fruiting.No direct streamflow readings were available this cycle to confirm how the drought is affecting local waterways, but sustained dryness like this is worth watching for its potential effects on salmon habitat, the kind of condition Adopt A Stream Foundation tracks in local streams through the season. Separately, this cycle's regulatory water quality checks on discharge permits in the county, including the Everett Ship Repair facility's permit, haven't flagged any new impairments. The drought, not a discharge event, is the story to watch here this summer.

Three of the largest permitted dischargers in the Fraser Lowland are currently listed in significant non-compliance with federal regulators, and in all three cases the problem is not a documented pollutant release but a failure to report at all. The Bellingham wastewater treatment plant, which discharges near Bellingham Bay, missed its required monitoring report entirely, the first time this plant has shown up flagged at this location. At the same time, the Bellingham City stormwater permit and the Port of Bellingham permit are both listed more than 30 days late on their compliance-schedule progress.The distinction matters. This is not three facilities caught discharging over their limits; it is three facilities whose self-reported data has gone missing at the same time, which means there is currently no way for anyone outside those facilities to check what is actually entering the bay. The federal impairment list covering roughly 50 nearby water bodies, including the Bellingham Bay segments near the plant, shows none officially impaired, but most carry a label of insufficient data to determine impairment, a designation left over from the 2018 assessment cycle. That is not the same as clean water. It is another version of the same gap: an absence of monitoring record rather than a finding either way.Late summer is exactly when a reporting blackout like this is worth watching closely. Warm, still water this time of year already carries elevated risk for dissolved oxygen stress and algal blooms in nutrient-loaded systems, and Bellingham Bay sits downstream of a treatment plant now sitting quiet on its reporting duty. None of this proves a discharge problem. It does mean that the paperwork which would let anyone confirm one way or the other is simply not there, across multiple permits, at the same time.

The Friday Harbor sewage treatment plant has exceeded its Clean Water Act discharge limits twice this year. Suspended solids in its effluent ran 381% over the permitted limit at the end of March and 296% over limit again on July 24, six days ago. Biochemical oxygen demand, a measure of how much a discharge will deplete oxygen in the water it enters, exceeded limits by 150% and 71% in those same two periods. Same outfall, four months apart: that pattern points to a persistent operating problem rather than a single bad day.The plant is not an outlier here. It is one of five wastewater facilities near the San Juan Islands currently flagged by the EPA for significant non-compliance, and among the 21 Clean Water Act permitted facilities within roughly 15 km of the islands, 14 have active violations right now and 17 have had at least one in the past year. Across all of them, the total penalties assessed to date add up to zero dollars. Violations are being logged; nothing is following from them.What isn't known matters here too. No dissolved oxygen, turbidity, or bacteria reading near this outfall was available to check whether the surrounding water is actually showing stress from these discharges. This is a paper record of exceedances, not a measurement of harm in the surrounding waters. But repeated overages at the same discharge point, with no enforcement response on record, are worth watching as the water warms into late summer, the season when oxygen demand in coastal waters is already at its highest.

Copper discharge from the Puget Sound Naval Shipyard in Bremerton has now exceeded its Clean Water Act permit limit for two consecutive quarters, and the trajectory is the notable part: 24% over limit in the quarter ending December 2025, then 101% over limit the following quarter, a roughly fourfold jump in a single reporting period. The outfall empties into Sinclair Inlet, a working embayment that drains directly into central Puget Sound.Copper is a slow, subtle poison rather than an acute one, which is exactly why it deserves attention at these levels. Research on juvenile coho and Chinook Salmon has shown that dissolved copper impairs their sense of smell at concentrations well below what would otherwise be considered dangerous. Salmon depend on olfaction to detect predators and to navigate home to spawn; a fish doesn't need to be poisoned outright to have its odds quietly worsened. That relationship between smell and survival is precisely why copper limits are set where they are, and it's why blowing past one by double is a materially different problem than nudging over it.The pattern isn't confined to one outfall. King County's West Point Treatment Plant, near Discovery Park on the same stretch of Puget Sound, logged a strikingly similar arc over the identical two quarters, exceeding its zinc limit by 95% and then 128%. Two of the largest permitted dischargers into central Puget Sound worsening on different metals over the same span is a signal worth taking seriously in its own right, even before any water-quality sampling confirms measurable effects on fish moving through these waters.

Forked Globetail hover flies (Sphaerophoria sulphuripes) are not common sightings these days, but one turned up nectaring on low-growing composites on July 28 — late July is when adults are most active and visible. These hover flies are genuine pollinators of open-ground wildflowers, and their presence signals something ecologically valuable: unimproved meadow edges and grasslands that have been steadily lost across the lowlands to development and invasive plant encroachment. iNaturalist flags this species as threatened.Two other invertebrates that iNaturalist flags as threatened appeared within the same month: a Purple-backed Cabbageworm Moth (Evergestis pallidata) and a California Pyrausta Moth (Pyrausta californicalis). Three records in a midsummer window is not enough to claim anything definitive about population status, but it is an unusual cluster of iNaturalist-flagged sensitive invertebrates in a single month, and worth attention as the meadow edges they depend on continue to narrow.

Vine maple (Acer circinatum) has begun turning color by mid-July — a shift that typically doesn't occur until September or October when fall rains return and the light angles lower. This is not an isolated quirk. Beaked hazelnut (Corylus cornuta) is coloring, Canada goldenrod (Solidago canadensis) bloomed six weeks ahead of schedule, and bunchberry dogwood (Cornus canadensis) has already completed its fruit cycle by mid-month. These events are moving through the understory in tandem, a pattern of heat stress rather than scattered phenological variation.Vine maple is one of the most structurally important trees in the Pacific Northwest understory, forming the mid-canopy shade that keeps stream banks cool and shelters the shallow pools where juvenile coho and cutthroat spend their first summers. Early senescence now means that canopy shade — already weakened by a warm July — begins to fail months before fall rains arrive to replace it. The consequence reaches deeper than the forest floor: young fish in streams across the region are losing thermal refuge precisely when they need it most.

Indian plum is already yellowing and dropping its leaves in mid-July—a full two months ahead of its typical fall senescence. For a shrub that leafs out first each February, this precocious collapse reads as a clear signal: the San Juan Islands are gripped by summer drought stress. The region sits in one of the driest rain shadows in the Pacific Northwest, catching barely half the rainfall of Seattle less than 90 miles away.Oceanspray is showing the same compressed urgency—flowers and ripening fruit visible at once this week, as though the plant is racing to complete its reproductive calendar before soil moisture runs out entirely. Both species are reading the same ecological cue: a dry July is telling the understory that summer is already over.As temperatures climb through the week, air quality is expected to worsen as well, likely from smoke drifting in from inland fires. This seasonal combination of heat, drought, and smoke has become the defining summer signature for these inland waters.

Dot-tailed Whitefaces (Leucorrhinia hudsonica) emerged at Sunset Pond on June 20—small dragonflies marked by a single yellow spot at the tail tip of the males, now winging across the emergent vegetation. These odonate are meticulous about their habitat: they breed only in clean, still wetlands with adequate dissolved oxygen and dense emergent growth. Their arrival carries ecological weight, because the seasonal window tightens fast. By mid-July, shallow ponds like this one face peak thermal and oxygen stress, as warm water becomes hostile to aquatic larvae and decomposition loads spike. The Dot-tailed Whiteface is sensitive enough to that shift that their successful emergence reads as a reliable water-quality pass for early summer.In the Fraser Lowland, this species is tethered to sphagnum-edged pond habitat that was far more abundant before agricultural drainage remade the coastal flats over the past century. Seeing them here alongside Cardinal Meadowhawks and Pacific Forktails—with seven dragonfly and damselfly species recorded across the lowlands over the past sixty days—suggests that enough of those wetland remnants remain intact to sustain a full emergence season. The resilience is real, but fragile.

Canadian bunchberry (Cornus canadensis) has ripened to red fruit in just three weeks — completed July 12 — while kinnikinnick berries are coming in alongside it. The acceleration is matched by Canada goldenrod, which opened July 13, nearly six weeks ahead of its typical late-August bloom.Mid-July here is a narrow fruiting window—thrushes and cedar waxwings have only days to exploit this brief pulse of seed and sugar before the resource passes. Earlier phenology is compressing the timeline for migrants and residents alike, testing whether their movements stay synchronized with the plants they depend on.
