In October 2009, water from the Wimmera River trickled into Lake Hindmarsh for the first time in 13 years. The 2010 Victorian floods raised water levels higher many birds returned to the lake. After the January 2011 Victorian floods, it was hoped the Wimmera River would fill the lake and overflow into the northern lakes. However, outlet creek remained dry and the lake again awaits its next flooding event.
