Avon River, aperennial stream of theManning River catchment, is located in theUpper Hunter region ofNew South Wales, Australia.

Avon River rises in the northern foothills of theBarrington Tops, south ofCarsonville in theBerrico Nature Reserve within theBarrington Tops National Park, and flows generally north-east, joined by five minortributaries, before reaching itsconfluence with theGloucester River, nearGloucester, south of the confluence of the Gloucester River with theBarrington River. The river descends 412 metres (1,352 ft) over its 42 kilometres (26 mi)course^[1]

The catchment area of the river benefits from melting snow in spring. Gloucester district, although incredibly hot in the main summer months, nevertheless has an annual rainfall averaging 1,300 millimetres (51 in). As a result, combined with the merging streams and rivers, periodic serious flooding occurs in the Avon Valley at Gloucester, sometimes cutting all transport links.^{[citation needed]}

The Gloucester River eventually flows into the Manning River, a major waterway which flows into theTasman Sea through a minordelta east ofTaree.^[2]

In 2004, assessments of water sampling done in 1997 by the NSW Environment Protection Authority, revealed poor water quality, with high levels of nutrients leading to excess algae.^[3] Along the river, downstream fromStratford, bank erosion and the invasion by exotic plant species have degraded the river.
