'Nature' magazine carried an article in 1977,( just after Sir Peter Scott had given a scientific genre name to 'Nessie' ),that 'Koskolteras Rhombopterix' might have been seen in Lake Kos Kol in
I could find nothing since then that had been reported about the monster.
This is not to be confused with Aidakhar the monster of Lake Kok-Kol.
Kok-Kol lake lies in the
Kazakhstan area Dzambul.. The report of a creature seen in the lake said that the body reached fifteen metres in length and that the head was a metre and eighty centimetres in size. During the seventies and early eighties Soviet scientists took a great interest in the lake. In 1986, an expedition went to the area to research the evidence but didn’t come back with any proof.. One of the characteristic attributes of the monster, was said to be its call. However, in January 1986 a report in the Soviet press agency Tass, (and also later in Western newspapers),by the team of the Soviet Academy of Sciences concluded, that after studying the findings of the expedition, the sounds were caused by noise of air being sucked into the cracks connecting the deep lake with underwater caves. The reports of turbulence in the lake were also attributed to these air ducts. Despite the official explanation, however, locals still believe in the monsters.
I translated with the help of google and a dictionary , the little information there was on these two creatures , so I apologise for any errors.
