Course and features
Growee River rises on the northern slopes of the Great Dividing Range, below Hefrons Hole, northeast of Rylstone and flows generally northwest then north northeast, then north by west then northeast, joined by three minor tributaries before reaching its confluence with the Bylong River near Bylong. The river descends 407 metres (1,335 ft) over its 42 kilometres (26 mi) course.
The Bylong Valley Way crosses the Growee River at multiple points from below Growee Mountain in the south to near the town of Bylong in the north.
