A lot of science and community knowledge exists about the water needs of plants and animals in rivers and wetlands. Using this knowledge, specific studies have identified the types of flows a particular river needs or the wetting and drying patterns needed by a wetland.

Flow studies tell us about the timing, watering duration and amount of water needed by native plants and animals. Many flow studies have been developed for rivers and wetlands that receive environmental water.

Environmental water management plans are also developed. These plans use the flow studies and help guide watering of rivers and wetlands that receive environmental water. 

Below is a list of available flow studies and environmental water management plans.

Western region

Environmental water in the western region is shared between the Wimmera and Glenelg systems and the Wimmera–Mallee wetlands. Important waterways that receive environmental water include sections of the Glenelg, Wimmera and MacKenzie rivers and Mount William, Burnt and Bungalally creeks, as well as priority wetlands formerly supplied by the Wimmera–Mallee channel system.

Northern region

Gippsland region

There are four systems in Gippsland that can receive environmental water: the Latrobe (including the Latrobe River and lower Latrobe wetlands), Thomson, Macalister and Snowy.
