The Macquarie Without Development model covers the headwater catchments and river reaches of the Macquarie River basin. This includes the Macquarie River and explicit representation of its major tributaries such as the Fish River, Cudgegong River, Bell River, and Talbragar River, amongst others. It also covers the headwater catchments and river reaches of the Bogan River, and various floodplain distributaries and anabranches in the lower reaches of the Macquarie River basin. The model extends downstream to locations upstream of the Barwon River. The model extent does not include the Castlereagh River.
