It is perhaps best known to tourists as the location of the purported sightings of a monster named Issie, and as the largest lake on Kyūshū island[1] with a surface area of Script error: No such module "convert". and a shoreline length of Script error: No such module "convert"..[2]
Deterioration
The development of the areas surrounding Lake Ikeda has caused the quality of the water to decline since 1955.[2] Other causes include an irrigation project, developed for agricultural field and households in the area, which was initiated in 1965, for it the courses of three nearby rivers were diverted into the lake.[2] The irrigation system has been in operation since 1982, resulting in a considerable improvement of the water quality[2] although since the 1950s the transparency of the lake, though still ranked No. 7 in the world,[1] has decreased from Script error: No such module "convert". to approximately Script error: No such module "convert"..[2]
Animals
Lake Ikeda is known to harbour large eels, some six feet in length.[1] In 1998, a benthological survey was conducted in the lake, which found that there were no zoobenthos, although two tubificid oligochaetes and a chironomid were found.[3] The lake was already considered oligotrophic until the 1940s, but one theory for the further drop in underwater life is that the existing life in Lake Ikeda has been affected by global warming.[3]

Issie
Script error: No such module "Nihongo". is a Japanese lake monster said to lurk in Lake Ikeda.[4] It is described as being saurian in appearance. The naming convention is analogous to "Nessie" (the Loch Ness Monster).
According to mythology, Issie was a white mare who lived together with her foal on the shore of Lake Ikeda. However, when the foal was kidnapped by a samurai and Issie was unable to find it, she jumped into the lake and her despair transformed her into a giant, saurian beast, which since then frequently surfaces, trying to find her lost child.[5] The creature was reportedly photographed in 1978 by a man who went by the name "Mr. Matsubara". Twenty other people reportedly also saw the creature swimming in the lake in 1978; they described it as black and having two humps, each about 5 meters (16 feet) long.[5][6]
