EPHEMERAL

adj. lasting only a day; short-lived, transitory

Ephemeral things are transitory, existing only briefly. An ephemeral waterbody is a creek, stream, river, pond or lake that only exists for a few days following precipitation or snowmelt. They are not the same as intermittent or seasonal waterbodies, which exist for longer periods, but not all year round. Examples of ephemeral streams are the Ugab River in Southern Africa, and a number of small ephemeral watercourses that drain Talak in northern Niger. Lake Carnegie in Western Australia and Lake Cowal in New South Wales are ephemeral lakes.
