Loch Ness Monster vs Ogopogo: what's the difference?

Nessie and Ogopogo are the world's two most famous lake monsters, one in a Scottish loch and one in a deep lake in British Columbia. Both are described as long, dark animals with humps, but the details differ.

The big differences

  • Where: Loch Ness in the Scottish Highlands, compared with Okanagan Lake in BC's Okanagan Valley.
  • Look: Nessie is usually a long neck and small head, like a plesiosaur. Ogopogo is more serpent-like: several humps in a line and a horse- or goat-like head.
  • Size: Nessie estimates run 20 to 40 feet. Ogopogo is often said to be 40 to 50 feet.
  • History: Nessie goes back to St Columba's 'water beast' in 565 AD, but the modern legend began in 1933. Ogopogo grew from Syilx (Okanagan) traditions of N'ha-a-itk and settler reports from the 1870s.

Could they be the same thing?

They're separate legends, but they share explanations offered by sceptics: boat wakes, swimming deer or moose, floating logs and standing waves on calm days. A 2018 DNA survey of Loch Ness found lots of eel DNA and no reptile DNA.
