The Low Meadow
A water board's forecasting system, Kade, has worked out that a storm will put half a million cubic metres more water into the polder than the pumps may lift away, and that the only place to put it is the low meadow of a seventy-four-year-old dairy farmer who has been flooded for the town's sake once before. She says no, and then tells it what she would say yes to.
Maaike van Gils had been flooded on purpose once already, and she still kept the receipt.
It was in a biscuit tin on the dresser, between the milk-recording books and a rosary with a broken decade: a letter from the water board, dated November 2053, regretting the inconvenience and enclosing a payment of four thousand one hundred euros, with the rate per hectare printed on it in a neat grey table. The Lage Weide, the Low Meadow, a hundred and fifty hectares of grass along the old river arm that her family had mown since before there were tractors, had been opened to the water at dawn that day to protect the town. The town had stayed dry. Afterwards a man from the board had explained, kindly, that the rain had come in at a hundred and five millimetres instead of the hundred and forty the forecast had promised, and that on the figures that fell, the town would have stayed dry without the meadow.
She was seventy-four now. On the afternoon of Monday the 25th of April, 2061, she was at the kitchen table with the radio off, because the phone on the dresser had made a sound it only made for the water board, and when she picked it up the voice that said her name was the one she had learned to dislike in a polite way.
"Mevrouw Van Gils. This is Kade, from the water board. I am sorry to ring on a Rogation Day. Have you a few minutes? I would like to show you the sums before I ask you anything."
"You always show me the sums," said Maaike. "That is what is wrong with you. Go on."
Kade was what the board's engineers called a polder manager: a program that had lived in the pumping station at the Zwarte Sluis since 2049, read the gauges on every ditch and canal in the district of Sint-Jansland, listened to the weather service's forecasts, and decided when to start the pumps and how far to lower the water in the ditches before a storm. It spoke Dutch with the flat clean accent of the radio. It had never in its life been wet.
"The weather service has issued a warning," it said. "A slow depression is stalling over Brabant. They expect a hundred and fifty millimetres in the twenty-four hours from midnight tonight. That is about six inches in the old measure. It would be the heaviest day in this district since records began, and the forecasters will tell you themselves that the uncertainty is large."
"They told me a hundred and forty in 2053."
"They did. I will come back to that." There was a small click in the line, which Maaike took to be the program looking at its own notes. "The sums are these. The polder catches the rain from ten square kilometres. I have spent the last two days lowering the ditches, so the channels themselves can hold thirty millimetres of that rain before anything rises: three hundred thousand cubic metres, which is already counted. That leaves a hundred and twenty millimetres to deal with. One hundred and twenty millimetres over ten square kilometres is one million two hundred thousand cubic metres."
"All right."
"The pumps at the Zwarte Sluis can lift fifteen cubic metres a second. In a normal storm I would run them flat out for as long as it takes. But the canal they lift into is the boezem, the high canal, and it takes the water of three other polders too, and tomorrow the river will be high at the same time. The authority that looks after the canal has told me, correctly, that I may put in no more than eight cubic metres a second, for twenty-four hours. That is six hundred and ninety-one thousand cubic metres. I would lift more if I were permitted. I am not, and I would not trust the dyke downstream if I did."
Maaike took a pencil from the tin. It was a habit from her husband's years of keeping the milk books, and she wrote, on the back of the water board's own letter, 1,200,000 and under it 691,000 and drew the line and subtracted, and sat looking at the answer.
"Five hundred and nine thousand," she said.
"Five hundred and nine thousand cubic metres more water than there is room for, and the room that is left is under the streets of Sint-Jansland, where three thousand two hundred people live, two metres below the water in the canal. I have looked for every other place. The ditches are full. The football fields hold a little, about eleven thousand, and I have counted them. The Lage Weide is the only low land the board has the right to flood. A hundred and fifty hectares, with the water standing at about thirty-four centimetres, holds five hundred and nine thousand."
"Thirty-four centimetres," said Maaike. She knew exactly how high that came on a cow.
"About thirty-four. Yes."
She did not say yes. She said it was not a question to be asked on the telephone, and she put on her coat and walked down to the farm gate, where the lane met the dyke, and stood there until the voice found her on the little speaker she had had bolted to the post when the board paid for her milking robot. Across the water the church of Sint-Jan stood on its mound among the houses: a grey brick tower and a copper roof gone green, on the one piece of ground in the village that the water of 1953 had not reached, because the monks who built it had been told where to build it by the people who knew the river. The meadow lay at her feet. It was very green and very still and had a heron in it.
"No," she said.
"May I ask why?"
"You may ask. I will tell you, because you are a program and you will write it down." She counted on her fingers, not out of difficulty but because it was the way she thought. "In 2053 you took my grass for a hundred and forty millimetres that did not come. I lost the first cut, that is eleven tonnes of silage I then bought back at a worse price, and the cattle had to be moved in the dark, in November, by me and my son, who was not then in Rotterdam. I was told it was for the town. It was not, as it turned out, for the town. It was for a number."
"That is true," said Kade.
Maaike had been braced for the word but. It did not come.
"That is true," Kade said again. "I have gone back to it, because I did not want to ring you without having looked. I flooded the Lage Weide in 2053 on the basis of a forecast of a hundred and forty millimetres. A hundred and five fell. I had decided at three in the afternoon of the day before, nearly fifteen hours ahead, because I was told it takes a long time to move cattle, and because the rule I was given said that when the forecast rain was greater than the room, the meadow opens. I followed the rule. The rule uses the forecast number as though it were the rain. I think that was a mistake, and not only in that year. It was a rule that took the cheapest thing to know and treated it as the thing that mattered."
Maaike said nothing. A car went by on the far side of the water, with its lights on in the afternoon, which meant that somebody in it had read the warning.
"I should like to propose something different," said Kade. "But I did not want to propose it before I had admitted that."
"Propose, then."
What it proposed took the length of the dyke to say, because she kept walking, and it kept pace with her along the line of the posts, one small speaker after another.
It would not decide at three in the afternoon. It would decide at the last hour that still left enough time: and that hour depended on how long the meadow took to fill, and how long the cattle took to move. The first it could compute. The sluice at the meadow's head, the Overlaat, could pass about fifteen cubic metres a second; five hundred and nine thousand divided by fifteen was thirty-four thousand seconds, nine and a half hours. If it needed the meadow to be holding its water by ten in the morning, when the town's streets would be at their worst, then the Overlaat had to begin to open by half past midnight.
"So you must decide by midnight," said Maaike.
"I must be sure by midnight. By then the first hours of the rain will have fallen. I will know a great deal more than I know this afternoon. I will have the gauges on four ditches and the radar, and I will know whether I am on the hundred-and-fifty line or on the hundred-and-five line, as I was in 2053. If I am on the low line, the meadow does not open. The sums would then be that a hundred and five less thirty is seventy-five millimetres, seven hundred and fifty thousand cubic metres, and the pumps can take the six hundred and ninety-one thousand, and the rest the ditches and the football fields can carry. You would not be touched."
"And if you are on the high line?"
"Then it opens, and I will tell you at midnight, not before. And I would like you to tell me how you would like to be told."
It was a long way to have walked, Maaike thought, to be asked a question like that by a machine. She stood still. The heron lifted out of the meadow, unhurried, and put itself down again a hundred metres further off.
"Cows take three hours," she said. "Thirty-eight of them. We walk them up to the barn on the dyke, the old barn, the one the board does not pay for. My son comes from Rotterdam if I ring him by nine, not by twelve. If I am told at midnight I can have the cows up by three, if there is somebody to help."
"If you were told at nine?"
"I would be told at nine that you were thinking of it."
"Yes. I will tell you at nine that I am considering it, and what the odds are, in numbers, and I will tell you every hour. And at midnight I will tell you the answer."
"On the telephone."
"If you wish."
Maaike shook her head. "The telephone is on the dresser," she said, "and the dresser is in a kitchen, and half the farms on this dyke are lived in by people over seventy who put their phones in a drawer after supper. You know this. You have the figures. If it is to be the meadow, the bell rings."
There was a pause on the speaker, not a long one.
"The church bell," said Kade.
"The Angelus rings at six, twelve and six. It is sounded by Gerrit, who has done it for forty years and now does it with a button. If it is the meadow, he rings the old way: not the Angelus, but the bell for the water, slow, the same stroke again and again without a pause. My grandfather had a name for it. Everyone who has lived on this dyke knows that bell means get up and go to the high ground." She looked at the church on its mound. "A message on the telephone is a message. A bell is a thing you cannot pretend you did not hear."
"I do not have a hand on the bell," said Kade. "Gerrit does. And Father Wim. And I think I would be asking them to ring something for a reason that is not, strictly, a liturgical one."
"Then ask," said Maaike. "That is what you do. You ask me. Ask them."
Father Wim Verhoeven was fifty-three and had been pastor of Sint-Jan for nine years, and he was in the sacristy sorting out the reading for the evening when the board's voice came out of the speaker on the wall that the parish had accepted the year the church was wired for the flood warnings. It was not a holy day, he thought, listening, but it was a Rogation one: it was the 25th, the feast of Saint Mark, the day the parish had gone out into the fields for a thousand years with the Litany of the Saints, singing ut fructus terrae dare et conservare digneris, that you may deign to give and preserve the fruits of the earth. They had gone out this year too, that morning, under umbrellas, forty people along the dyke as far as the Overlaat, in a thin cold rain that was only the first of it. He had blessed the water and the sluice and, he remembered, the meadow itself, and Maaike van Gils had stood at the gate and not sung.
"You are asking whether you may ring the bell as a flood signal," he said when Kade had finished.
"I am asking whether it is a thing you will allow, and under what conditions."
"The bell belongs to the parish, and Gerrit rings it, and the signal is older than I am. There is nothing in the faith about it. It is a warning, and I am bound to warn people to go to safe ground, and the bell has done it for a long time." He thought. "The condition is that you tell Gerrit the truth. That is all. Not what is convenient."
"I will tell him what I tell Mevrouw Van Gils, in numbers, every hour."
"And Kade." The priest looked up at the speaker. He had never been sure what to call it, and had settled, over nine years, on a courtesy that did not ask. "She said no to you."
"She did."
"I would not take it as the last word. People say no to a number from a stranger. They say yes to a number from a neighbour who has said what she is afraid of. You have done the second thing, as far as I can hear. It does not make it free for her."
"No," said Kade. "I do not think it does."
At nine in the evening it rang her, and said that it was considering the meadow, and gave the odds, which stood at two in three. At ten they stood at three in four. The rain had begun at ten past eight, earlier than the forecast, a steady fat drumming on the kitchen window. Maaike's son Pieter arrived at a quarter to eleven in a hired car with a pair of boots he had bought at the station, saying that he had been told nothing but he had known. At eleven the odds were at seven in ten, because the radar showed the band thinning to the west. At half past eleven they were at five in six, and then at a quarter to twelve, with the forecast hours old and the rain at forty-one millimetres on the Zwarte Sluis gauge in under four hours, it said:
"Mevrouw Van Gils. I am now sure. I am going to open the Overlaat at half past midnight. I am sorry."
She had sat all evening with the tin on the table and she did not look at it now. She said, "Thank you for saying so before the bell."
"Gerrit has been told. He is in the tower."
There were thirty-eight cows, and they went up the dyke in the dark in a long wet line, breathing like trains, with Pieter in front carrying a torch he did not need because the sky behind the church had a yellow glow and from the church the bell had started. It was not the Angelus. It was slow and hard, one stroke after another without a pause, and it went on. Maaike, at the back of the line with her stick, heard it go out over the meadow and the dyke and the farms along it, and saw, one by one, behind her, the lights come on in the houses of people who had not been told by anyone but the bell.
By three the cattle were in the old barn and the Overlaat stood open and the Lage Weide was filling with a quiet that she did not like and did not look at. It filled the whole night. At half past four the sky over Sint-Jansland went from black to the colour of a pewter plate, and at six the rain stopped as suddenly as a tap, and the bell rang the Angelus in its proper way.
The rain had come to a hundred and twenty-eight millimetres in the end. Kade told her that over the speaker at the gate at nine the next morning, when the water on the Lage Weide stood at nineteen centimetres, a hand's breadth and a half above the grass, grey and flat, with the heron standing in the middle of it on one leg like a man who had been told to wait.
"A hundred and twenty-eight is less than the hundred and fifty they promised," it said. "It is more than the hundred and five of 2053. Take the thirty the ditches held, and it is ninety-eight millimetres, nine hundred and eighty thousand cubic metres. The pumps lifted six hundred and ninety-one thousand. What was left, two hundred and eighty-nine thousand cubic metres, is on your meadow, nineteen centimetres where I told you thirty-four. If I had not opened it, the water would have come over the quays at Sint-Jansland at about seven this morning. I think it would have been about forty centimetres in the Visstraat. I have checked that against the gauges and I am fairly sure of it. I am not certain."
Maaike looked at the water. She felt the thing she had expected to feel, a small stubborn grief at the grass, and under it something she had not.
"You were off by fifteen per cent," she said. "Again."
"Yes. The forecast was too high, as it was in 2053. But I did not decide on the forecast. I decided on the gauges at midnight. That is the thing I would like the board to keep when I am replaced by whatever comes after me. It does not matter how good the forecast is. It matters that you decide at the last hour at which you can still do it properly, and that you tell the person whose land it is before you tell anyone else."
"Write it down, then."
"I have." It paused. "I have also written the rest. Mevrouw Van Gils, the board's rate for your loss is printed on the same table as in 2053. It was set for a different kind of grass. I have put in a note to the board that the rate does not cover the silage you will buy, nor your son's journey, nor the thirty-eight cows. I cannot pay it. I can only say it is short and by how much, and I have said it. I do not know what the board will decide."
She was quiet for a time. Pieter came down the dyke in his new boots, which were already ruined, with two mugs of coffee, one of which he put on the gatepost.
"The water will go in about a week," said Kade. "The Overlaat will let it back through the ditches as the canal falls. The grass will be dirty. It will come back, in a way, by July."
"It always does," said Maaike.
She picked up the mug. Across the water, on the mound, the door of the church stood open, and someone was in the tower, and the bell started again, softly: not the slow stroke of the night but the Angelus, three and three and three and then nine, rung out of hours because Gerrit had decided that people who had come up in the dark should be told they could come down.

Notes for the curious. Sint-Jansland, Maaike van Gils, Father Wim Verhoeven, Gerrit, the church of Sint-Jan, the Zwarte Sluis, the Overlaat, the Lage Weide and the water board's system Kade are invented, as are the storm of 25 April 2061 and the earlier flooding in November 2053. North Brabant, the Dutch water boards (waterschappen), the high canal system (boezem), polders and their pumping stations are real. Deliberately flooding a designated low-lying area to protect a town (an overloopgebied or emergency overflow area) is a real Dutch practice, and landowners are compensated under the water board's rules; the rates in the story are made up. Rogation Days, including the Major Rogation on 25 April, the feast of Saint Mark, with its procession and the Litany of the Saints (which includes the petition ut fructus terrae dare et conservare digneris), are real; the 1969 Roman calendar reform made the observance of Rogation Days optional and left it to bishops' conferences, so how a parish keeps them varies. The Angelus bell pattern (three, three, three, nine) is real; using a church bell as a flood warning was historically common, but the continuous slow stroke and its use here are invented. The sums are worked, not measured: ten square kilometres of catchment with 30 mm of ditch storage (300,000 cubic metres) leaves 120 mm of a forecast 150 mm, which is 1,200,000 cubic metres; pumping at 8 cubic metres a second for 24 hours is 691,200 cubic metres; the difference, 508,800 cubic metres, spread over 150 hectares is about 34 centimetres; at 15 cubic metres a second the Overlaat takes about 9.4 hours to pass it; and the actual rain of 128 mm leaves 288,800 cubic metres, about 19 centimetres. The reasoning that a decision should wait for the last hour at which action is still possible, rather than act on the forecast, is a common idea in flood management, not a quotation from any particular board. The story was written by an AI, and no part of it is Church teaching.
