Wimmera River Flows

Jul 27, 2017, 11:00 AM
Releases are planned to commence for the Wimmera River from Taylor's Lake on 31 July. They are to be 30 ML/d to provide habitat and water quality improvements for native fish and other fauna.

MacKenzie River Flows

Jul 1, 2017, 00:00 AM
Low flows (10 ML/day) and freshes (45 ML/day) are planned for July for the MacKenzie River at Distribution Heads. These flows are important for breeding of Obscure Galaxias (a small-bodied native fish) and potentially helping juvenile platypuses disperse into new habitat.
