Gwydir environmental water priorities 24–25
Moderate rainfall and constant river flows were experienced across the Gwydir catchment during 2023–24. Major flooding occurred across the
Gwydir River floodplain during March and April 2023.
Water managers used water for the environment during the 2023–24 water year to support fish communities in rivers and create connections to
the Barwon River, the Mallowa Creek, and low flows into the Gingham Watercourse to fill waterholes by season’s end.
In planning for 2024–25, water managers have applied:
- a set of principles and triggers to guide the watering of key water-dependent assets
- an adaptive approach to support fish and downstream ecological connectivity.
As of June 2024, the El Niño–Southern Oscillation outlook is neutral. That is, neither La Niña nor El Niño conditions are favoured as oceanic and atmospheric indicators have returned to neutral levels. International climate models suggest neutral El Niño–Southern Oscillation conditions will persist through the southern winter, but there are some signs that La Niña conditions could form later in the 2024–25 water year.
