KALANCHAK, Ukraine — A makeshift dam of sand and clay, covered with patches of grass, blocks one of Europe’s great canals. Beyond it, swans drift in the trickle of water that remains. A duck slides into a wall of reeds below the bare, concrete banks.
This quiet spot just north of Crimea may not look like much. But some Ukrainians fear it could be the thing that ignites an all-out war with Russia.
“Putin could send his troops in here at any moment,” said Olha Lomonosova, 38, explaining why she had packed a getaway suitcase this year at her home upstream. “He needs water.”
President Vladimir V. Putin of Russia ordered some of the troops he had massed on Ukraine’s border this spring to pull back last month, but as many as 80,000 remain within striking distance, and many Ukrainians believe that the threat of a new invasion remains. A prime reason is the 250-mile-long Northern Crimean Canal linking Crimea with Ukraine’s Dnieper River: the main source of water for Crimea until Mr. Putin annexed it in 2014 and Ukraine, in a secret operation, hastily built the dam to block the canal’s flow.

assurances that even tourists to Crimea will not go thirsty.
Blocking the canal, a senior official in the de facto Russian government controlling Crimea said in February, represented “an attempt to destroy us as a people, an attempt at mass murder and genocide.” Moscow has pledged to spend $670 million to address the water shortage, but this year reservoirs have been running dry and water is being rationed.
Ukrainian officials are unmoved. Under the Geneva Convention, they say, it is Russia’s responsibility as an occupying power to provide water, and they add that sufficient underground aquifers exist to provide for the population. The Kremlin says that Crimea willfully joined Russia in 2014, aided by Russian troops, after the pro-Western revolution in Kyiv; nearly every government in the world still considers Crimea to be part of Ukraine.
“No water for Crimea until de-occupation,” said Anton Korynevych, the representative for Crimea of President Volodymyr Zelensky of Ukraine, spelling out government policy. “Period.”
