There has been much talk over the years about whether there is a monster in the lake. At 514 metres (approximately 1,686 feet), Hornindalsvatnet is the deepest in Europe.
The men claimed they spotted the creature at 21:30 after seeing ripples in the water and do not believe a boat passing at the time caused the ripples.
They took their boat to that area of the lake after allegedly seeing the serpent in the water the men took, but the creature was gone by the time they arrived, according to Mr Solvik.
“However, there was nothing more to see when we got there, just ripples on the lake. There was nothing in the water then”.
The men contacted the local newspaper, Fjordingen, and showed them the pictures they had taken of the creature.
Its editor, Bengt Flaten, did not doubt the story the men gave. He said that the pictures clearly show something in the water and vouched for the man as he knows them.
Describing the pictures, Mr Flaten declared, “We can see two arches, then the tail section at the back, and one can see what is probably the head at the other end.”
This is not the only story surrounding mysterious creatures in lakes. The most famous is the Loch Ness Monster in Scotland.
Sightings of the Loch Ness Monster have been reported in the press for almost 80 years. - theforeigner
NOTE: Well, this story certainly went viral...though, trying not to seem too cynical, this may have been a ploy to prop up the tourist trade. We'll see...Lon
Hornindalsvatnet is Norway's and Europe's deepest lake, officially measured to a depth of 514 metres (1,686 ft). Its surface is 53 metres (174 ft) above sea level, which means that its bottom is 461 metres (1,512 ft) below sea level. The village of Grodås lies at the eastern end of the lake in Hornindal and the village of Mogrenda is located on the western end of the lake in Eid. The E39 highway runs past Mogrenda and the lake.
Since the age of the Vikings there have been tales of creatures from Norway's depths. Dragons are commonly known as Lindworms, monstrous serpents with or without hind legs though less likely to inhabit water. In Norway, tales of marine monsters appear vary throughout the country. The coasts of Norway are reportedly haunted by the terrifying Kraken. Sea serpents, with their glowing eyes and long manes, are said to live in varied locations. The Norwegian lake Seljordsvatn is famous for its claimed inhabitant, a serpent known as Selma.
More human but equally terrifying is the Draug (Ghost of the Sea), a skeleton dressed in oilskins and sou’wester, sailing in a halfboat. If fishermen or sailors see him, they know that they’re almost certain to drown. Some times he’ll go ashore and sit in newly built boats. People sitting where the draug has been seated are bound to drown. Before the ship goes down, the halfboat will turn up and sail along with the ship and lead it into dangerous waters.
Then there is the Nøkken, a water being, found in lakes and rivers. It's a shapeshifter and can turn up as a handsome young man playing the fiddle or the harp so beautifully that people go into the water without recognising that they can’t swim, and then they drown. Other times he shows himself as a white horse, walking invitingly near the river - or lakeside, but if you try to ride this horse, he will jump directly to the bottom of the water with you. He can also be seen as a ghastly head with glowing eyes, easily taken for a small island with red lights.
As for Hornindalsvatnet, eels are known to inhabit the lake, but these don't grow nearly to the size of the creatured reported. According to a friend familiar with Norwegian lore, there have been tales of magical beings around Hornindalsvatnet since the 16th century...but he is not familiar with reports of water creatures
