Nimrim, The Waters of
(limpid, pure), a stream or brook within the country of Moab, which is mentioned in the denunciations of that nation by Isaiah (Isaiah 15:6) and Jeremiah (Jeremiah 48:34). We should perhaps look for the site of Nimrim in Moab proper, i.e. on the southeastern shoulder of the Dead Sea.
