Wollemi Creek

The Wollemi Creek, a partly perennial stream of the Hawkesbury-Nepean catchment, is located in the Central Tablelands and Blue Mountains regions of New South Wales, Australia.

Course and features
The Wollemi Creek rises below Kekeelbon Mountains on the southern slopes of Mount Mounundilla, within the Wollemi Range, in remote country within the Wollemi National Park, north northwest of the locality of Putty. The river flows generally south southeast and south southwest, generally adjacent to the Putty Road, joined by seven minor tributaries before reaching its confluence with the Colo River in the upper reaches of the Colo Gorge, about 25 km south southeast of Glen Davis. The river descends 549 m over its 84 km course.

The upper Wollemi Creek has two main sources, one originating at about 800 m altitude 5 km east of Mount Monundilla, and the other due south of that mountain. Both flow through rough deep gorges at about 600 m in permanent dry weather flows, and fast flowing flood, until their confluence at about 300 m, due west of Putty, from where the creek flows eventually into the Colo.

The primary inhabitants of the upper creek are yabbies, eels, and possums. Some ancient massive gums populate the lower gorges and very few signs of non–native infestations are apparent, one notable exception being mistletoe which infests the upper branches of the oldest trees.
