The maximum impact is expected to be on around 0.2 m in the north-west of the Condamine Alluvium and less than 0.05 m across the majority of the area. It is predicted that there will be a net loss of water from the Condamine Alluvium to the Walloon Coal Measures of about 735 ML/year over the next 100 years due to CSG development.
