Tradition tells that the Loch was actually formed in ancient times by locals damming the burn for water supply. Another tells the same in order that a mill could be fed with constant water - though no mill can be found. If this latter tradition is true however, the fairy creature here could have been a brownie - though they are generally more a lowland elemental. One of the reasons the place has been named after the little people is that when certain light falls on it, at the right time of day and year, green triangular shapes emerge from the water formed by deposits hidden beneath the surface (hence the original Gaelic name, Lochan Uaine, or the Green Loch). Norman Douglas said how "another story is that the local people would deposit their sheeps' fleeces in the Fairy Loch overnight, wish for them to be dyed a certain colour, and overnight the fairies would carry out their wish."
