Editing Colo River (section)

==Course==
The Colo River rises on the [[Great Dividing Range]], northeast of [[Newnes, New South Wales|Newnes]], formed by the [[confluence]] of the [[Wolgan River]] and the [[Capertee River]], which respectively drain the [[Wolgan Valley|Wolgan]] and [[Capertee Valley|Capertee]] Valleys north of [[Lithgow, New South Wales|Lithgow]]. Colo River flows eastwards and then south through a deep gorge in the northern section of the [[Blue Mountains (Australia)|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, New South Wales|Windsor]]. Tributaries of the Colo include the [[Wollangambe River]] and [[Wollemi Creek]]. The river descends {{convert|214|m}} over its {{convert|86|km|adj=on}} [[watercourse|course]].<ref name=bonzle/>

At {{NSWcity|Colo}}, the river is crossed by the [[Putty Road]] (B84).

Parts of the area surrounding the river, including both the [[Blue Mountains National Park]] and the Wollemi National Park have received [[List of World Heritage Sites in Oceania|World Heritage listing]], due in part to the discovery of the [[Wollemia|Wollemi Pine]], often described as a 'living fossil' from the age of the dinosaurs. The Colo River gorge contains many boulder-rapids that alternate with deep pools. Even though this area is relatively close to the [[Sydney]] metropolitan area, the Colo River flows through the largest wilderness area in New South Wales. Local volunteer bush regeneration groups such as the "Friends of the Colo" have been helping eradicate invasive exotic weeds in the area surrounding the river.{{citation needed|date=February 2013}}
