Course and features
The Mirrool Creek (technically a river) rises in the Ingalba Nature Reserve, about 15 kilometres (9.3 mi) west by south of the town of Temora, sourced by runoff from the Great Dividing Range. The creek flows generally north northwest, west, north by west, and west again for approximately 115 kilometres (71 mi), joined by four minor tributaries, before becoming indefinite approximately 3 kilometres (1.9 mi) south southwest of Barellan. The Mirrool Creek rises again approximately 20 kilometres (12 mi) east of Griffith and flows for approximately 75 kilometres (47 mi) west southwest, and to the south of Yenda, Bilbul, Hanwood and Griffith, before heading northwest by north and flowing into the Barren Box Swamp, where the creek does not drain above the land surface. The Mirrool Creek rises again southwest of the village of Goolgowi and flows west and then west southwest, joined by one minor tributary, before reaching its confluence with the Lachlan River, north northwest of the town of Hay. The creek descends 191 metres (627 ft) over the entire 264-kilometre (164 mi) course.
The creek is crossed by the Newell Highway at the locality of Mirrool and at the town of Ardlethan; the Kidman Way south of Hanwood and north of Darlington Point; the Mid-Western Highway northeast of Hay; and the Cobb Highway northwest of Hay.
