The Making of a Wetland Wonderland

Gwydir Valley Flow Updates

After a number of dry years, conditions are looking better in the Gwydir. Flows in late 2020 and early 2021 started the process of recovery, with further rainfall, flows and wetland flooding throughout 2021 and 2022. Vegetation is responding well to the flows. Delivering water for the environment during the dry times has helped native plants and animals to hang on. This also helped them to bounce back when wetter conditions returned.

Check out the Gwydir Valley flow updates for the 2021-22 water year below:

Toorale Floods

The end of 2021 saw higher than average rainfall across the Northern Murray-Darling Basin which produced the largest flows through the Darling River since 2012, with a peak of 73,000 ML/day at the Bourke gauge. Usually, the Warrego River flows into the Darling just south of Bourke. However, during this event water levels in the Darling got so high that water flowed over the banks of the Darling to the floodplains and riparian areas and also backed up into the Warrego channel!
