Kandos Wier built across the lower section of a small canyon From 1930 now Wollemi National Park 

Dunns Swamp was created when the Kandos Weir was built in 1930, to provide water for the Kandos Cement Plant.
The dam is located in a spectacular pagoda landscape. The pagodas were formed by the weathering of rocky outcrops of sandstone, long before the Kandos Weir was built.
Pagodas are not usually associated with water but at Dunns Swamp they are immersed in it. The higher pagodas offer fantastic views over the area.
There is an ancient Aboriginal Hand Stencil site at Dunns Swamp.
Dunns Swamp offers a range of activities including swimming, boating, camping, bushwalking and fishing. Ganguddy Camp Ground is a large and well equipped camping area.
Kandos Weir on the Cudgegong River was built by the Kandos Cement Company in 1930 to supply water to the Kandos Cement Plant.
The Kandos Weir impoundment is known as Dunns Swamp.
The dam is operated and maintained by Cement Australia. The company works closely with the NSW National Parks and Wildlife Service to ensure the valuable water resource is well managed.
As a result, Cement Australia has guaranteed a water supply for its own operations and created a unique environmental wonderland at Dunns Swamp.
