The Yarriambiack Creek, an inland intermittent watercourse of the Wimmera catchment, is located in the Wimmera region of the Australian state of Victoria. Rising on the northern slopes of the Great Dividing Range, the Yarriambiack Creek flows generally north and drains into Lake Coorong, one of a series of ephemeral lakes, northeast of .
The name of the creek is thought to derive from Jarambuik, the name of a sub-group of the indigenous Wotjobaluk people, also once spelt Yarriambiac, Yarramberger and Yarrambeak.[3]
The Yarriambiack Creek is a distributary[4] of the Wimmera River. It leaves the river near Drung Drung, approximately east of .
The watercourse flows northwards through and empties into Lake Coorong just east of . The watercourse flow is intermittent and depends almost entirely on the level of the Wimmera River. After not flowing for most of the previous 15 years, it flooded in September 2010 and January 2011. Water was released from the Wimmera River in 2012, flowed through the creek and ended in Warracknabeal. There are a number of weirs built along the creek to hold water. The Yarriambiack Creek descends over its 141km (88miles) course.[2]
At Warracknabeal,, and Hopetoun there are picnic spots, camping areas, gardens and walking trails.
The creek is crossed by the Henty Highway at multiple points between Warracknabeal and Hopetoun.
