Minor flooding occurs in Huonville on a regular basis. The main area affected is on the northern side of the Huon River and Wilmot Street. Some 13 residences are located in this area. Severe floods occurred in 1901, 1947, 1958 and 1960.
An automatic flood warning station operated by the Bureau of Meteorology is located at Judbury. The Bureau issue flood warnings in respect of the Huon River and refer to expected and/or actual river heights at Judbury.
As a general rule river levels at Judbury will produce the following:
3.00 metres - minor flooding of agricultural and horticultural land along the river flats with some stock losses. Closure of the Channel Highway at Huonville.
6.00 metres - moderate flooding of agricultural and horticultural land along the river flats with some stock losses and damage to fences. Flooding of low-lying areas of Huonville with the possibility of water damage to some dwellings. Closure of the Channel Highway at Huonville.
7.00 metres + - as above, water will enter some commercial premises; it may be necessary to evacuate the occupants of several dwellings. Closure of the Huon Highway between Wilmot Road and Huonville Bridge. Depending on tidal conditions the Huon Highway near Clarks Jetty at North Franklin may also be closed.
There is a time difference of approximately 2 hours between flood peaks at Judbury and that peak reaching Huonville.
Flood plain mapping of Huonville and environs has been undertaken. If you wish to ascertain if a property is shown with the 'flood plain' please contact the Council offices during normal office hours.
In 2000 Bureau of Meteorology received Federal Government funding to develop a 'low cost - low technology' flood warning system. The Mountain River was recognised as a river that met the Bureau's criteria to trial the project with the flood warning system subsequently installed.
The gauge provides a message to the Huon Valley SES Unit on the increasing river height towards the top end of the river. This then enables appropriate response to be provided.
Flood plain mapping of the Mountain River has also been undertaken. If you wish to ascertain if a property is shown with the 'flood plain' please contact the Council offices during normal office hours.
Geeveston is subject to flooding from both Riley's 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 subject to inundation thus isolating Geeveston and other communities south thereof. Whilst this was for a relatively short period the effect on the provision of emergency services especially ambulance/medical should be noted.
The catchment areas feeding both Nichols Rivulet and Agnes Rivulet have the potential to impact on the township of Cygnet. The areas most likely to be affected are the recreation oval and the foreshore area previously accommodating Burton's factory. Low-lying roads may be made impassable and some bridges are susceptible to damage mostly near the township. This could lead to road access isolation of part of the township.
