After the thirtieth consecutive month with out rain, the townsfolk of San Francisco de Conchos within the northern Mexican state of Chihuahua collect to plead for divine intervention.

On the shores of Lake Toronto, the reservoir behind the state's most necessary dam – known as La Boquilla, a priest leads native farmers on horseback and their households in prayer, the stony floor beneath their ft as soon as a part of the lakebed earlier than the waters receded to at the moment's critically low ranges.

Amongst these with their heads bowed is Rafael Betance, who has voluntarily monitored La Boquilla for the state water authority for 35 years.

"This could all be underwater," he says, motioning in direction of the parched expanse of uncovered white rocks.

"The final time the dam was full and prompted a tiny overflow was 2017," Mr Betance recollects. "Since then, it is decreased 12 months on 12 months.

"We're presently at 26.52 metres beneath the high-water mark, lower than 14% of its capability."

Little surprise the area people is beseeching the heavens for rain. Nonetheless, few count on any let up from the crippling drought and sweltering 42C (107.6F) warmth.

Now, a long-running dispute with Texas over the scarce useful resource is threatening to show ugly.

Below the phrases of a 1944 water-sharing settlement, Mexico should ship 430 million cubic metres of water per 12 months from the Rio Grande to the US.

The water is distributed by way of a system of tributary channels into shared dams owned and operated by the Worldwide Boundary and Water Fee (IBWC), which oversees and regulates water-sharing between the 2 neighbours.

In return, the US sends its personal a lot bigger allocation (almost 1.85 billion cubic metres a 12 months) from the Colorado River to produce the Mexican border cities of Tijuana and Mexicali.

Mexico is in arrears and has did not sustain with its water deliveries for a lot of the twenty first Century.

In April, on his Fact Social account, US President Donald Trump accused Mexico of "stealing" the water and threatened to maintain escalating to "TARIFFS, and possibly even SANCTIONS" till Mexico sends Texas what it owes. Nonetheless, he gave no agency deadline by when such retaliation may occur.

For her half, the Mexican President, Claudia Sheinbaum, acknowledged Mexico's shortfall however struck a extra conciliatory tone.

Since then, Mexico has transferred an preliminary 75 million cubic metres of water to the US by way of their shared dam, Amistad, situated alongside the border, however that's only a fraction of the roughly 1.5 billion cubic metres of Mexico's excellent debt.

Emotions on cross-border water sharing can run dangerously excessive: in September 2020, two Mexican individuals had been killed in clashes with the Nationwide Guard at La Boquilla's sluice gates as farmers tried to cease the water from being redirected.

Amid the acute drought, the prevailing view in Chihuahua is that "you possibly can't take from what is not there", says native knowledgeable Rafael Betance.

Watch: Farmers within the US and Mexico wrestle as decades-old treaty fuels water disaster

However that does not assist Brian Jones to water his crops.

A fourth-generation farmer within the Rio Grande Valley in Texas, for the previous three years he has solely been in a position to plant half of his farm as a result of he would not have sufficient irrigation water.

"We have been battling Mexico as they've not been dwelling as much as their a part of the deal," he says. "All we're asking for is what's rightfully ours below the treaty, nothing further."

Mr Jones additionally disputes the extent of the issue in Chihuahua. He believes that in October 2022 the state obtained greater than sufficient water to share, however launched "precisely zero" to the US, accusing his neighbours of "hoarding water and utilizing it to develop crops to compete with us".

Farmers on the Mexican aspect learn the settlement otherwise. They are saying it solely binds them to ship water north when Mexico can fulfill its personal wants, and argue that Chihuahua's ongoing drought means there isn't any extra obtainable.

Past the water shortage, there are additionally arguments over agricultural effectivity.

Walnut timber and alfalfa are two of the principle crops in Chihuahua's Rio Conchos Valley, each of which require plenty of watering – walnut timber want on common 250 litres a day.

Historically, Mexican farmers have merely flooded their fields with water from the irrigation channel. Driving across the valley one rapidly sees walnut timber sitting in shallow swimming pools, the water flowing in from an open pipe.

The grievance from Texas is apparent: the apply is wasteful and simply averted with extra accountable and sustainable farming strategies.

As Jaime Ramirez walks by way of his walnut groves, the previous mayor of San Francisco de Conchos exhibits me how his trendy sprinkler system ensures his walnut timber are correctly watered all 12 months spherical with out losing the dear useful resource.

"With the sprinklers, we use round 60% lower than flooding the fields," he says. The system additionally means they'll water the timber much less often, which is especially helpful when the Rio Conchos is simply too low to permit native irrigation.

Mr Ramirez readily admits, although, that a few of his neighbours aren't so conscientious. As a former native mayor, he urges understanding.

Some have not adopted the sprinkler methodology due to the prices in setting it up, he says. He is tried to point out different farmers that it really works out cheaper in the long term, saving on power and water prices.

However farmers in Texas should additionally perceive that their counterparts in Chihuahua are going through an existential risk, Mr Ramirez insists.

"This can be a desert area and the rains have not come. If the rain would not come once more this 12 months, then subsequent 12 months there merely will not be any agriculture left. All of the obtainable water must be conserved as consuming water for human beings," he warns.

Many in northern Mexico imagine the 1944 water-sharing treaty is now not match for objective. Mr Ramirez thinks it could have been sufficient for circumstances eight a long time in the past, nevertheless it has did not adapt with the instances or correctly account for inhabitants progress or the ravages of local weather change.

Again throughout the border, Texan farmer Brian Jones says the settlement has stood the take a look at of time and will nonetheless be honoured.

"This treaty was signed when my grandfather was farming. It has been by way of my grandfather, my father and now me," he says.

"Now we're seeing Mexico not comply. It's extremely angering to have a farm the place I am solely in a position to plant half the bottom as a result of I haven't got irrigation water."

Trump's more durable stance has given the native farmers "a pep in our step", he provides.

In the meantime, the drought hasn't simply harmed farming in Chihuahua.

With Lake Toronto's ranges so low, Mr Betance says the remaining water within the reservoir is heating up with unusual pace and creating a possible catastrophe for the marine life which sustains a once-thriving tourism business.

The valley's outlook hasn't been this dire, Mr Betance says, in the whole time he is spent fastidiously recording the lake's ups and downs. "Praying for rain is all we now have left," he displays.
