الوصف: The Gwydir catchment, located in the northern Murray-Darling Basin, extends from the Great Dividing Range west to the Barwon River. Downstream of Moree, the system fans out into a broad alluvial nearterminal floodplain. Numerous anabranches and distributary channels characterise the lower half of the Gwydir catchment, with the Mehi River and Moomin Creek to the south, and the Lower Gwydir River, Gingham Watercourse and Carole Creek to the north. Commonwealth environmental watering targets channel, wetland and floodplain assets including the Lower Gwydir, Gingham and Mallowa wetlands with expected environmental outcomes downstream (west) of Tareelaroi Weir on the Gwydir River. Climatic conditions were dry for most of the Long Term Intervention Monitoring Project (LTIM Project), especially since 2017 when rainfall has been well below the long-term average. Above average rainfall during August - October 2016 stimulated the largest natural flow event through the system, but since then, flows have been dominated by regulated releases from Copeton Dam. Commonwealth environmental water was delivered to the channels of the lower Gwydir system and wetlands via a number of watering actions, cooperatively, as a combination of both Commonwealth and State managed water. This report considers the combined influence of both Commonwealth and State managed environmental water sources on hydrologic and environmental responses. Environmental watering in the Gwydir catchment is delivered under a multi-year wetting and drying strategy to protect and maintain the condition of the wetlands and rivers within the system. During the planned ‘wet’ years, such as 2014-15 and 2018-19, watering aims to inundate core wetland areas and improve their condition and resilience to dry phases. During the intervening ‘dry’ years, environmental watering is more targeted at smaller scale wetland watering and to provide in-stream flows to support native fish populations and protect critical refuge habitat. The largest inundation event during the ...
