Colo River

The Colo River, a perennial stream that is part of the Hawkesbury-Nepean catchment, is located in the Central Tablelands of New South Wales, Australia.CourseThe Colo River rises on the Great Dividing Range, northeast of Newnes, formed by the confluence of the Wolgan River and the Capertee River, which respectively drain the Wolgan and Capertee Valleys north of Lithgow. Colo River flows eastwards and then south through a deep gorge in the northern section of the Blue Mountains. The majority of the river lies in Wollemi National Park. The middle Colo is inaccessible, rugged and remote. The wilderness was saved from development, logging and damming in the late 1970s by the Colo Wilderness Preservation Society and other environmentalists. Emerging from the wilderness region, the lower part of the Colo River flows through a scenic, narrow agricultural valley and reaches the Hawkesbury River at Lower Portland north of Windsor. Tributaries of the Colo include the Wollangambe River and Wollemi Creek. The river descends over its 86km course.
