Lake Como didn't dry up. The drought threat is real

A sensational video circulating on TikTok this week claimed that Lake Como in northern Italy had disappeared after a 'geological rupture', showing what appeared to be a dry, cracked lakebed where the famous waters once sat. The footage and photos were entirely generated by artificial intelligence, according to a fact-check by France 24 published on Wednesday.

The debunking is straightforward: the lake has not vanished, and there has been no geological event. But the report notes that water levels in the lake have dropped because of drought — the same dry spell that has left much of northern Italy parched through an unusually hot August.

For Lombardy, the distinction between a hoax and the underlying reality matters. Lake Como is the centrepiece of a tourism economy that draws visitors from around the world to the region's lakeside towns, and the viral clip — even if false — feeds a perception of a landscape in crisis.

France 24's fact-check identifies the AI-generated nature of the images as the central problem, warning that such content can spread quickly and shape public perception of real environmental conditions. The outlet does not dispute that the lake's water levels have fallen; it attributes the drop to drought rather than any dramatic rupture.

The Lombardy bureau's interest in this story is twofold. First, the region's lakes — Como, Garda, Maggiore — are a cornerstone of its tourism revenue, and any suggestion that they are disappearing could deter the international visitors who fill hotels and restaurants from Bellagio to Sirmione. Second, the drought itself is a genuine concern for the regional economy, which depends on water for agriculture in the Po Valley and for the hydroelectric power that serves Milan's industrial hinterland.

The AI hoax also lands at a moment when foreign coverage of Italy is increasingly focused on climate stress. The same week, international outlets reported on West Nile virus outbreaks tied to warm weather and on heatwaves that have pushed Rome to test night-time tourism. The Como video, though false, taps into that same anxiety.

For now, the lake remains very much present. But the underlying drought is real, and the region's water managers will be watching the autumn rains closely. The hoax may be debunked, but the pressure on Lombardy's water resources is not.
