Wimmera River
 The Wimmera River is a river in Western Victoria Australia. It begins in the Pyrenees and flows northwards into Lake Hindmarsh and Lake Albacutya and exceptionally into a chain of ephemeral lakes further north in Wyperfeld National Park and the Big Desert Wilderness Park. In most years flows do not reach these terminal lakes and the river contracts to a series of pools.[citation needed] Its major tributaries include Mount William Creek and the MacKenzie River.
