Narrative

Ephyra Lake is a small, boomerang shaped lake to the west of Medusa Lake in the Vestfold Hills. In December 1992 the two lakes were joined by a narrow (about 1 m) and shallow (about 500 mm) connection. The maximum recorded depth of Ephyra Lake is 9 m although there may be deeper areas. Temperature and conductivity profiles of Ephyra Lake recorded in December 1992 indicated that a much saltier layer of water occurred beneath a depth of 7.5 m which was accompanied by increased water temperatures. Although the lake is occasionally connected to Medusa Lake it has a quite different salinity profile and mixing characteristics and therefore deserves to be recognised as a separate water body. Medusa Lake is named for its shape which is like a Medusa jellyfish. Ephyrae are the juvenile forms of such Medusae. The lake was named Ephyra Lake because it is close to and much smaller than Medusa Lake.

Named For
