Ogopogo or Naitaka the name given to a cryptid lake monster reported to live in Okanagan Lake, in British Columbia, Canada. Ogopogo has been seen by Native Americans since the 19th century.
The most common description of Ogopogo is a forty- to fifty-foot-long (12 to 15 m) sea serpent. It has supposedly been photographed and even been caught on tape.
Proponents of the Ogopogo's existence claim that the first documented sightings of the monster date back to around 1872, and occurred as the area was being colonized by European settlers.The earliest mention of the Ogopogo was the story of a man in 1860 leading horses that were swimming across the lake near Rattlesnake Island.
