The logger was where he'd left it in April, zip-tied to a length of rebar he'd driven into the cobble under the basalt ledge where Catherine Creek came out of the shade. Six months of silt had packed in around the housing. He knelt in the water and thumbed the cap clean until the serial number came up.
The optical shuttle took on the second try. Six months of readings at fifteen-minute intervals, somewhere north of seventeen thousand numbers, and the transfer bar crawled across a screen that had been cracked since the Minam trail in July, when he'd set his pack down on it without looking. He stayed squatting in the creek with his pants soaking through and let it crawl.
While it ran he held the handheld in the current and counted off a full minute, because the handheld lied if you rushed it. 11.8°C. He wrote it in the field book with the time, 05:47, and the sky condition, which was smoke. It had been smoke for eleven days. The canyon smelled like a woodstove with the damper shut wrong, and the light came through it yellow and flat, nothing in it casting a shadow.
The shuttle beeped. He disconnected, capped the logger, checked the tie, and waded back to the gravel bar where he'd left his boots.
He sat on a rock and scrolled. The spring pulse peaked in late April and fell off through May faster than last year. June's daily maximum went past 18 on the twelfth, eleven days earlier than the year before and nineteen days earlier than the year before that. Seven years on this site. You could read the acceleration from across a room.
The overnight minimum was what he'd come for. He scrolled to August, then September. It hadn't breached 9 until the twenty-third of August. After that it sat between 9 and 11 through the first week of September, then started up. Last night, the most recent reading in the file, was 12.4.
He wrote the number down. 12.4 was cold enough. A fish could spend a night at 12.4 and be fine in the morning. Whether 12.4 was a floor or a step on the way to 14 depended on which years you weighted and on whether you thought eleven days of smoke holding heat in after dark was weather or was September.
He pulled his boots on and got the pack up. Two more loggers today, Fly Creek and the upper reach above Vey Meadows, and then back to Fern's draw before dark.
The cache was forty minutes upstream, a steel ammunition box bolted under a bridge abutment that no longer had a bridge on it. He reached up under the concrete lip and worked the latch. Two sealed envelopes. A blister pack of AA batteries. A note from Sparrow in the block capitals she used when she wanted to be unmistakable.
BOTH OF THESE ARRIVED WITHIN SIX HOURS OF EACH OTHER. YOUR RAW FILES WENT OUT THROUGH THE NETWORK THREE DAYS AGO. I COULDN'T STOP IT AND I WOULDN'T HAVE. SORRY.
Three days. Three years of logger uploads from every site on his circuit, pushed out through the relay with the site notes stripped off. No calibration records. Nothing that told you which sensor had drifted and in which direction and by how much, and therefore which readings a person ought to throw out. The files would open clean on anybody's screen.
He opened the first envelope. Della's seal, the compact's pressed-clay mark, which she still used because digital signatures were switchable and clay wasn't. The body was in an aide's careful hand, the young one. The last line was Della's own.
Tam. The council sits Thursday. I need you to present the tributary assessment. Toppenish by Wednesday night. This is not a request I can make twice.
The second envelope had no seal, just a routing stamp out of Lapwai on a sheet off the church's laser printer. Darya's writing, small and even, the letters not quite touching each other.
Tam — I need field verification at Lower Granite before I can update the structural assessment. The intake screens, the juvenile bypass outfall, and the embankment seepage on the right abutment. My inspection data is twelve years old and it is what both sides are arguing from. I can get you escorted access through Alahmoot's people. Thursday or Friday. After that the window closes; Boone's people are talking about shutting the Lewiston road for the season and I can't tell whether that's posture or schedule. Bring your temperature data. I need to know what the tailwater is doing now, not what the model says it should be doing.
He read them both again, folded them, and put them in the waterproof pocket inside his jacket, against the shuttle with six months of Catherine Creek on it.
Two sides had read the same curves inside three days, come out opposite, and sent for the one person who could tell them which reading was right. He was not going to be able to tell them that. The readings were both right. That was the thing he had spent seven years building toward without meaning to.
Toppenish was three and a half hours by road if the road was open, and it usually was through Pendleton, because Boone kept I-84 running and charged for it. Lower Granite was four hours the other direction, out through the Wallowa foothills and down into the Snake canyon, assuming the Lewiston road held and Alahmoot's escort showed up where it said it would. Both trips started at La Grande. He was two hours from La Grande on foot, plus Fly Creek, plus Vey Meadows.
Today was Tuesday.
He put the batteries in the pack and closed the cache. He didn't write anything back to Sparrow. Whatever there was to say, she had already said it to herself in the three days it took her to decide not to stop it.
South of him, in the Blues or over in the Elkhorns, something was still burning. He hadn't seen it in eleven days. It had a taste now and not just a smell, charred pine on the back of his teeth.
The season hadn't broken.
He started upstream toward Fly Creek.
DELLA
The council table at Toppenish was a door, a solid-core interior door out of a demolished school, laid across two filing cabinets. Nine years she'd been using it. It was level and it held weight, which was more than the conference table it replaced had managed at the end.
She laid Reyes's sheets out across it. Eleven of them, handwritten, one site to a page. Reyes had numbered them and not ranked them, because Reyes never ranked anything. She wrote down what she saw and left the ranking to the people who wanted to fight about it.
Six sites in the upper Grande Ronde. Three in the Wenaha. Two in the Wallowa. Water present or not, flow by eye, substrate, fish seen or not seen, and at four of the eleven, where she'd had a thermometer, a temperature. The range ran 11.2 to 16.8. The 16.8 was the mainstem below Vey Meadows, which had never been a refuge and wasn't going to start being one. The 11.2 was the spring-fed side channel below Fern's draw, and under it Reyes had written: Juveniles present. Three, maybe four. Holding in the plume where the spring comes into the channel. Didn't have a thermometer, borrowed Fern's. No time to check it against anything.
Borrowed Fern's. So Reyes had been down at the garden, and the garden was still putting out cold water, which meant the second seep had come in and the designation hadn't killed the site after all. It had only turned the visible half of it into a political object while the water went on coming up somewhere else.
The council had been scheduled for Thursday for two months, and for two months it had been a formality. What changed it was the data. Three days ago the church pushed Tam's files out through the relay, three years of fifteen-minute temperatures from every site on his circuit, nothing attached, and both sides downloaded the same thing and read it in opposite directions inside of a day. Alahmoot's people took the mainstem numbers and concluded the corridor was lethal, so repair the dams and move the fish through mechanically. Her own people took the tributary numbers and concluded the cold water was holding, so open the dams and let the fish get to it. Same file, two arguments, and nobody in either room who had ever stood in any of the water.
What she needed from Tam was the aggregate. Not any one number, she could read a number, but the shape across seven years. Whether the cold patches were holding, and holding well enough to be worth opening the lower Snake for, and whether the hours in which an adult fish could move up through the warm reaches were still wide enough to call a window. Reyes couldn't answer that; Reyes collected and refused to interpret. Della couldn't answer it either. Her expertise was law and leverage. The questions belonged to Tam.
Cass came in with two cups of water, the morning ration, measured out, room temperature. She set one in front of Della and kept the other.
"He's not coming," she said.
"I don't know that yet."
"Darya sent him a letter too. Reyes told me."
Della drank half the cup. "Reyes told you."
"Reyes tells everybody everything. That's her whole job."
"Reyes tells everybody the same thing. That's not the same as everything."
Cass sat down across the door. She was twenty-three. She had Della's hands and her mother's mouth, and Della had trained herself over about four years not to look at the mouth during an argument.
"Can you present without him?"
"I can present the observations. I can't present what they mean."
"So present them and let the council work out what they mean."
"The council will work out what it already believes. Alahmoot's people will look at these temperatures and say the tributaries are marginal and getting worse, so there's nowhere for the fish to go and opening the river is a gesture. Our people will look at the same temperatures and say the tributaries are holding, and opening the river is the last chance to get anything to them." She set the cup down. "Both of those come out of the same eleven sheets of paper. That's why I want the man who's been in that water for seven years standing in the room and being complicated out loud, where people can watch him do it."
"And if he doesn't come?"
"Then I stand up there with eleven pieces of paper and a thermometer reading somebody borrowed."
Cass picked up the sheet with the 11.2 on it. "This one's Fern's place."
"Below Fern's place. The side channel."
"If you put it in front of the council you're putting her spring in the record. Again. The surveyor put it in the registry, and a registry's a list, nobody reads a list. The council record is an argument. You're going to use her water to argue for opening the dams, and then Alahmoot's going to use that same water to argue for repair, because cold water that close to the dam site means a working ladder would have something to work with." She set the sheet back down, squared it with the others. "It gets used either way. That's all evidence does."
Della didn't say anything for a while. Then: "When did you start sounding like Tam?"
"Somebody's got to, while he's off being neutral at people."
Della made a sound that wasn't quite a laugh and went back to the sheets.
The smoke had come up to Toppenish overnight. She could smell it through the window she kept cracked for airflow, because the building's ventilation had quit in June and nobody in the basin had the parts.
She pulled the sheet with the 11.2 on it out of the row and set it by itself at the head of the door, where she'd have to reach for it.
FERN
The sorghum was ready and the beans were not and the amaranth was a question she'd have to answer by Friday.
She stood at the edge of the ugly garden, the second seep, two hundred meters from the mapped spring, sulfur-stained and nobody's idea of anything, and looked at four months of work. The sorghum heads had gone heavy and dry and were bending the stalks over. She could cut today. The beans were still green in the pod, three weeks off brown if the weather held and less if a frost came through, and the forecast off the church's half-dead NOAA mirror said overnight lows at 34 by the weekend. A coin flip between a killing frost and one more week of growing.
The amaranth was the one giving her trouble. She'd put it in late because the second seep took longer to come in than she'd planned for. The water came up slower here, two degrees cooler, and the sulfur meant building a settling channel before she could irrigate anything. So the amaranth was tall and green with the heads forming and the seed not set. A frost before set and she lost the planting. No frost, fire weather holding, and it kept growing and she'd be cutting it green and drying it by hand, which was three days of work she didn't have, because the sorghum was ready now.
Three crops, three deadlines, and none of them had anything to do with the council meeting Reyes had told her about or the fire she could smell and couldn't see.
She heard the footsteps before she saw anybody. Gravel on the old logging track coming down off the ridge. She'd gotten good at people by their walk. Tam walked quiet and set his feet down one at a time like the ground might be thin. Reyes walked like she was late for something. The surveyor had walked like a man carrying equipment he was afraid of dropping.
This one was heavy and unhurried. Boots. Somebody not minding the noise.
She picked up the brush hook from where it leaned against the settling channel headwall and held it down along her leg. A tool that could be something else if it had to, and right now a tool.
The man who came around the bend was younger than her, maybe twenty-two, in a militia jacket with the Pendleton patch on the shoulder. Rifle slung across his back, paper in one hand. He stopped when he saw the brush hook.
"Looking for the hydrologist," he said. "Tam. Guy at the gate said he works this drainage."
"He's not here."
"He coming back tonight, or —"
"I don't keep his schedule."
The kid looked past her at the garden. She watched him take it in, the sorghum and the beans and the amaranth and the settling channel and the stain the seep had left down the rocks. He was counting. Boone's people counted everything; that was the whole method, knowing what was where and what it went for.
"Nice garden."
"It's not a garden. It's a weed patch."
He almost smiled. "That's a lot of sorghum for a weed patch."
"Sorghum's a grass. Grass is a weed."
He held the paper out. "This is for him. From Darya, came through our relay. She needs him at Lower Granite Thursday."
"I'll pass it along."
"She said it was urgent."
"Everything's urgent. Leave it on the rock."
He set it on the flat rock by the track and put a smaller rock on top of it, and he gave the garden one more pass with his eyes before he started back up the way he'd came, boots loud on the gravel until the ridge took the sound.
She waited until she couldn't hear him. Then she went and got the paper. Same wording as the copy that would be sitting in the cache, which meant Darya was running duplicates down every channel she had. Fern folded it into her back pocket.
She looked at the sorghum. The heads were dry. She could start now, in the cool, and have half of it down before the heat came up. Or she could stand here waiting on a man who might come in tonight and might not come in for three days, depending on which way he turned when he hit the La Grande road.
The sorghum didn't care about the council.
She picked up the brush hook and started cutting.
By noon she had half the stand down, the stalks lying in rows between the beds, drying in the yellow light. Her shoulders were cooked. The brush hook was the wrong tool — a sickle would have been right, or a machete if anybody still had one to trade — but it was what she had, and she'd worked out a short chop that took the stalk cleanly about four inches up and left enough stub that the roots kept hold of the dirt.
She stopped to drink out of the jug she kept in the shade of the headwall. The water tasted a little of sulfur. She'd stopped noticing three months ago. Visitors noticed. Tam had made a face the first time, and she'd told him the sulfur was the reason nobody else wanted the seep, and he'd said it was the best argument for drinking sulfur water he had ever heard.
The kid from Pendleton had inventoried her ground in about thirty seconds without writing a word down. The surveyor had put a number on the spring and the registry had put the number where anyone could find it, and now Tam's files were loose in the network without Tam attached to them, turning every cold seep in the drainage into a piece of an argument about dams she had never seen and fish she had never eaten.
She went back to the sorghum.
The light changed in the middle of the afternoon. Not darker. Yellower, and strangely even. She climbed the basalt outcrop at the lip of the draw where she could see south over the ridge, and there was nothing to see, only smoke in layers the color of a bruise. The smell had changed, though. It had gone greener and sharper, the way it did when the fire got into fuel it hadn't been in yesterday.
Tam told her once that fires used to lie down at night. Humidity came up, the fuels took on moisture, the thing went quiet until mid-morning and you got your work done in the dark. She had never seen one do it.
She came down off the rock and looked at her garden. Sorghum half cut. Beans green. Amaranth waiting on a frost that might not get here before something else did.
The go-bag had been packed since July. It sat inside the door of the root cellar she'd dug into the hillside above the seep, the cellar that also held the seed stock and the dried herbs and the tools and the three notebooks with her planting records and her variety trials in them. Water, food, headlamp, first-aid kit, a copy of the seed inventory. No seeds. The seeds were in glass jars, labeled by species and variety and harvest date. All of them together came to sixty-two pounds. The bag came to fourteen. She could carry both if she left everything else, and she could not carry both and move.
She had sorted it in her head every night since July. Which jars. Which varieties could be got again and which were the only ones left anywhere. The wild amaranth was the only one: a volunteer she'd found coming up out of the rubble of a collapsed barn outside Elgin, seed the color of dried blood, germinating in gravel, growing on nothing but what fell on it, now throwing heads as long as her forearm. The dryland bean she'd pulled out of a landrace mix over four seasons of selection, that was the only one. The sorghum she could get again out of the church cache at Heppner. The herbs she could get again if a person knew where to look, and she knew where to look.
Fourteen pounds of seed. Fourteen pounds she could carry and still move.
She went up to the cellar and started sorting jars.
TAM
The Fly Creek logger was gone.
The rebar was still in the cobble. The zip tie had been cut — a clean cut, knife or side-cutters — and the housing wasn't on the end of it. He went fifty meters downstream and checked the pools anyway. The creek was running two inches over gravel and clear as glass. No debris, no high-water mark, nothing that could have taken it off. Somebody had walked in and taken it.
He knelt where it had been and put the handheld in. 14.6. Warmer than Catherine Creek by almost three degrees, which was what you'd expect out of a shallower gradient with no canopy left on it. He could now tell anybody who asked exactly what Fly Creek was doing at 09:14 on the twenty-ninth of September. That and nothing else. No overnight minimum, no curve, nothing to set beside the other sites.
He wrote it down. Noted the logger missing. Noted the cut tie. September 29, 2071, 09:14.
In seven years he'd lost equipment to floods and to ice and once to a bear that had apparently formed an opinion about the housing. Never to a person. An Onset Pendant was worth something on its own; nobody had manufactured one in a long time, and the ones still circulating had been re-batteried twice and passed hand to hand like money among the few people still doing this work. But it was worth more with six months on it, and whoever cut it loose had six months of Fly Creek's overnight minimums, which is to say had an argument. Whoever they sold it to would have the argument, and no way of knowing that the sensor had been reading eight-tenths high since spring.
He packed up and started for Vey Meadows, two hours upstream, expecting to find nothing there either.
It was there. The download took four minutes. He scrolled it walking, shuttle in one hand, the trail going from gravel to ash where the '68 fire had come through and the soil had never got its duff back. The slopes above him were brush and bunchgrass now, no canopy, nothing shading the water. The mainstem was too warm, and he could see it in the file, daily maximums over 22 since mid-July and overnight minimums that never dropped under 16, and he could see it in the creek, moving slow and clear over pale cobble, no algae, because even the algae had limits, the surface holding the yellow light.
The smoke had done something he hadn't predicted. He stopped walking and scrolled back through the eleven days. The daily maximum had come down two to three degrees since the particulate settled in; enough sunlight was being blocked to cool the surface water through the afternoon. The overnight minimum had gone up about a degree and a half, because the same smoke held the heat in after dark. The daily swing was narrowing from both ends, and the swing was what a fish moved on, those few hours each night when it could go up through the warm reach and come out the other side still alive.
He pocketed the shuttle and kept going. The trail climbed through a stretch where the old timber road had washed out, and he picked his way across a gully that had not existed when he started this circuit. The charred pine was stronger up here.
The pouch at his sternum shifted when he leaned into the slope. Corin's key. Twelve years of carrying it. Search when ready. He pulled the strap down until the pouch stopped moving and went on up.
He came out on the old rail overpass above La Grande at 4:15. The people still living in the habitable buildings were indoors, waiting for the temperature to come off. A dog slept in the shade of a collapsed gas station canopy. From the overpass he could see the road west, cracked asphalt running into smoke toward Pendleton and eventually Toppenish, and the road northeast, which branched at the edge of town and started climbing immediately into what had been timber until '68 took the lower slopes. Brush and grass up there now. The same story the file told. Simpler system, less shade, less buffer, more exposed to whatever the sky did next.
He stood at the junction and got the field book out and didn't write anything in it.
Della would read the tributary numbers and say the cold water was holding, and she'd be right. The spring below Fern's draw was 11.2. Catherine Creek had come off a 12.4 night. Cold enough at the source. The problem was the corridor between the source and the ocean, which cooked for six hours every afternoon, and now the smoke was taking the night end of it too. Open the lower Snake and you delete the reservoir reaches, and the free-flowing stretches still run a fish through heat it can't hold out against.
Alahmoot would read the same corridor numbers and say a repaired ladder with the temperature-control gear working could pull cold water off the bottom of the pool and put it in front of the adults at the fishway entrance, which is more than a breached dam will do for them, a breached dam giving them the whole river at whatever temperature the river is. He'd be right too. It was a narrow case leaning on machinery nobody had maintained in forty years, but the physics underneath it were real.
Both of them had his files. Neither of them had his notes.
He could write Della the interpretation and send it through the church network. It would arrive as paper. Paper doesn't answer questions and it can't say I was standing in it at a quarter to six this morning. A document loses to a person in a room, and Della had taught him that by beating him with it twice.
He could not send Darya anything at all. The dam was a physical object and its condition was a physical fact, and the only structural baseline in the basin was twelve years old and belonged to a woman who knew precisely how stale it was and had been saying so into a wall for three years. She couldn't get past Alahmoot's checkpoint on her own. She could get past it with him, because he had spent seven years being the man who measured and did not advocate, and that was worth exactly one trip.
South, where the smoke was thickest, Fern would be cutting sorghum. She didn't know about the Fly Creek logger. She didn't know the fire had moved in the night. She knew a kid out of Pendleton had come down into the draw asking after him, which meant Boone's people had the second seep on a list now, which meant the ugly garden, the backup, the one nobody was supposed to want, was on a list.
The light was failing early. Not sunset, just particulate. Two hours of road he'd be willing to walk. West was flat and open. Northeast climbed.
He turned northeast. The grade came up hard out of town and the ash on the shoulder was deep enough to take a boot print, and he put prints in it for an hour before the light quit.
DELLA
Cass came back at dusk with a thumb drive and a face Della knew off her daughter, Cass's mother, dead eleven years: the face that said I did what you told me and I think it was a mistake.
"Physical copy of the raw logger files." She put it on the door. "Three years. Catherine, Fly, Meadow, the Vey Meadows mainstem, two on the Wenaha, and the spring channel below Fern's draw. No site notes. Nothing on calibration, nothing on drift. Fifteen-minute temperatures. Same file everybody else pulled down three days ago."
"I know what it is."
"Then you know a temperature curve with no notes on it is a shape. A person can make a shape say whatever they need it to say."
"I don't want it to say what I need. I want it to say what it says."
"Then you need Tam."
"He went to the dam." Not a question.
Cass nodded. "Reyes's circuit caught it. He left La Grande going northeast, somewhere around four-thirty."
Della put the drive into the tablet that ran off the building's array, the one device she kept charged, the one screen she allowed herself. Thousands of rows came up. Date, time, temperature, and nothing else; seven years of a man standing in cold water, and the man four hours out of reach and going the other way.
She opened Catherine Creek. Found September. Found last night. 12.4.
She could stand up in front of the council Thursday and say that the overnight low at Catherine Creek on the twenty-eighth of September was 12.4 degrees, that this sat inside the range juvenile fish can rear in, that the cold-water refuge was holding. All of it true. All of it one night.
She opened the spring channel below Fern's draw. He had a logger in there. She hadn't known that until the relay pushed the files, and she sat with it a second, because it meant he'd been watching that water for two years without mentioning it to anyone, which was the most Tam thing she could think of.
The overnight minimums ran 10.8 to 11.6 across the whole two years and barely moved with the season. Groundwater. The spring was delivering water at nearly the same temperature no matter what the surface streams were doing.
She looked at the line on the cracked screen. Flat, while everything around it moved, because the water was coming up from deep enough that the surface hadn't reached down to it yet. Yet was his word. Still was hers, and still was the word that opened dams.
Fern's spring. Water coming out of the ground at the same temperature year after year, on a piece of ground belonging to a woman who had asked, politely and more than once, to be left out of it.
Della took a pen out of the cup and started writing.
She would present Thursday. She would present without him. The spring would be the center of the tributary case, because it was the best evidence in the basin and because a council will believe a flat line faster than it will believe eleven sheets of a wanderer's handwriting. Alahmoot would take the same number and build his ladder on it. Fern would hear about it in a month from Reyes, or sooner from somebody in a jacket with a patch on the shoulder.
She wrote the site designation at the top of the page, the surveyor's number and not the name, because a number was what the record took. Under it she wrote the first line of the argument.
Smoke came in through the cracked window. The tablet said sixty-two percent. Enough to work to midnight if she kept the screen down.
She kept the screen down. She worked.
- Fires that burn overnight: A 2026 study found that annual potential burning hours across western North America increased 36% from 1975 to 2024, with about one in seven active fire days reaching peak intensity at night rather than afternoon.
- Monitoring gaps after wildfire: A Pacific Northwest synthesis found that hundreds of stream gauges collect water-quality data, but monitoring locations don't consistently overlap where fires actually burn, leaving post-fire watershed response poorly understood even in a well-instrumented region.
- Cold-water refuges mapped small: A field study in the upper Grande Ronde documented 99 cold-water patches averaging 5.8°C cooler than surrounding water, but many were shallow, sedimented, or lacked cover, meaning thermal advantage alone didn't make them viable habitat.
- Stream permanence as probability: A USGS data product now assigns Pacific Northwest stream segments a probability of maintaining year-round flow rather than a binary classification, but the administrative forms that govern water rights and habitat designations still require a category.
