There is a myth that the lake has no bottom and this is the deepest lake in Utah. This is a popular myth of about 20 lakes in Utah so of course it can't be true for each. There is a myth that there are two Spanish cannons at the bottom of the lake. Stories have been passed down for decades about the Moon Lake Monster. There are several books that talk about Spanish gold mines in the area.
