Some remote villages gathered to take group photos holding protest signs. Locals and Yakutia's media posted photos and videos of the brown water drawn from the river.
Alrosa said at the time that the river was safe despite the accident, which they blamed on abnormally heavy rains.
Russia's environment watchdog in October estimated the damage to the Vilyuy basin at 22.1 billion rubles (over $330 million, 290 million euros) but last month said Alrosa will not be held accountable as the accident was caused by a "natural disaster."
Community leaders in Yakutia however are convinced the company provoked the accident when it moved its mining equipment on the river without permission.
The dispute is likely to continue for years, with local residents powerless and forced to accept a compromised water supply, Dmitriyeva said.
"People suffer more from events like this because they lead a traditional way of life," she said.
