The Lake Baikal 'swimmers'
A story told since the 1990s says that in 1982 seven Soviet military divers training in Lake Baikal met three-metre-tall swimmers in silvery suits and helmets, with no breathing gear, at about 50 m depth.

The account
In the usual version the divers tried to throw a net over one of the figures and were flung to the surface; three died of decompression sickness because the recompression chamber was too small. The account reached print through the Soviet ufologist Vladimir Azhazha, who heard it from two diving instructors, Mark Shteynberg and Gennady Zverev; they said a general, Demyanenko, had told it in a safety lecture at Lake Issyk-Kul. It is often attributed to Soviet files declassified in 2009, but Brian Dunning of Skeptoid showed it circulated before then and called it at best a fourth-hand anecdote. An English version appears in Paul Stonehill and Philip Mantle's 'Russia's USO Secrets' (2016). No name of a dead diver, unit record or medical file has been published.
The sceptical view
No primary document or named casualty has surfaced; the story passed through several retellers. Baikal is ringed by towns and intensively studied, and silvery shapes glimpsed at depth could be nerpa seals or simply a cautionary tale grown in the telling.
The researched reading
A fourth-hand military anecdote with no primary record. Most likely service lore; the original event, if any, is undetermined.
| Explanation | Weight | Why |
|---|---|---|
| A cultural story | 40% | The story reached print through Vladimir Azhazha from two diving instructors who said a general told it in a safety lecture: a chain of retelling typical of service lore and cautionary tales. Its frequent attribution to 2009 declassified files is wrong. |
| Undetermined | 40% | No named casualty, unit record or medical file has been published; without primary documents the core event cannot be confirmed or excluded. |
| Something known, misidentified | 15% | If something lies behind it, silvery shapes glimpsed at 50 m in poor light (nerpa seals, a carcass, other divers) could have grown into giant swimmers. |
| Genuinely anomalous | 5% | Read literally, the account describes non-human swimmers without breathing gear; nothing independent supports it. |
Official position: No official Soviet or Russian document about the incident has been published.
