Recent works around Skinners Creek Huonville are designed to help mitigate flood risks in surrounding areas but flooding may still happen in severe rain events.  If Skinners Creek overtops, Sale Street and surrounding properties may become flooded.

If Mountain River floods, the areas most at risk of flooding include the Huon Valley Caravan Park, Huonville plus nearby Glen Road and Wilmot Road.

Kermandie River can cause flooding around Geeveston and isolate surrounding areas – see the Geeveston Flood Guide – https://www.ses.tas.gov.au/geeveston-flood-guide/

Huon Valley Council and the State Emergency Service are currently working on flood guides for Huonville and surrounding areas – https://www.ses.tas.gov.au/plan-prepare/flood-plan/

Further guidance:

Flood plain mapping of Huonville and environs has been undertaken. Contact the Council for more information about specific properties located within the flood plain.

Current river height levels for the Huon River

Mountain River

The Bureau of Meteorology operates a flood warning system on the Mountain River.

The gauge provides a message to the Huon Valley SES Unit on the increasing river height towards the top end of the river.

Flood plain mapping of the Mountain River has also been undertaken. To find out if a particular property is located within the flood plain, contact the Council.

Geeveston area

Geeveston is subject to flooding from both Rileys Creek and the Kermandie River.

Flooding in December, 1995 resulted in houses in Arve Road and Dover Road areas being flooded.

In December 1995, the Huon Highway at the junction with Scotts Road was flooded, isolating Geeveston and other communities further south.

Cygnet area

The catchment areas feeding Nicholls Rivulet and Agnes Rivulet have the potential to impact on the township of Cygnet.

The areas most likely to be affected are the Cygnet Recreation Ground and the foreshore area previously accommodating Burton’s factory.

Low-lying roads may be impassable and some bridges near the town are susceptible to damage. This could lead to road access isolation for part of the township.
