The Tidbinbilla River is a perennial stream that is part of the Murrumbidgee catchment within the Murray–Darling basin, and is located in the Australian Capital Territory, Australia.

Location and features

Tidbinbilla River rises on the eastern slopes of the Brindabella Ranges in the south-west of the Australian Capital Territory (ACT), below Billy Billy Rocks in Tidbinbilla Nature Reserve, within Namadgi National Park. The creek flows generally north-east before reaching its confluence with Paddys River, south-west of Tuggeranong Town Centre. The creek descends 708 metres (2,323 ft) over its 13-kilometre (8.1 mi) course.^[1]

In the years after the 2003 Canberra Bushfires, an existing weir on the river has been used to maintain large downstream ponds as part of conservation efforts.^[2]

Environmental concerns

In 2012, heavy downpours caused damage to the existing river system with erosion damaging the river's ability to hold water. In coordination with local landowners and stakeholders, the Mulloon Institute is currently undertaking rehydration works in order to primarily reduce erosion amongst other benefits.^[3][4]
