Much of Westerway township is prone to flooding, as is the lower part of Mount Field National Park.  There are some private properties along the river upstream of Westerway that can become flooded.<\/p>\n\n\n\n

Heavy rain in the Tyenna River catchment can also flood Gordon River Road, isolating many properties.<\/p>\n\n\n\n

Agricultural areas and the picnic area at Mount Field National Park can be impacted by more common heavy rain events in the Tyenna catchment. The entrance to the National Park may be closed.<\/p>\n\n\n\n

Areas around Ellendale may also become isolated due to flooding around the Ellendale Road intersection with Gordon River Road if there is also flooding along the Derwent River. If there is widespread rain around the Derwent River catchment, all areas around the Tyenna River may become isolated for possibly a few days.<\/p>\n\n\n\n

The maps show the likely areas to be flooded in a rain event that has a 2%, 1% and 0.5% chance of happening any year (% Annual Exceedance Probability). Events with a 2% chance of happening any year can have major impacts around Westerway, inundating homes, other buildings and roads, and isolating many properties.  You are likely to experience this level of flooding at least once in your lifetime.  Tasmanians need to be prepared for levels of flooding most people may not have experienced.<\/p>\n\n\n\n

The Tyenna River is fast flowing, and so flood waters are likely to be hazardous. Flood waters are likely to drop quickly once rain stops falling in the catchment.<\/p>\n\n\n\n

The area most recently had moderate flooding in July 2016, when the lower part of Mount Field National Park was flooded.  Westerway experienced major flooding in March 1931 and May 1948. This impacted buildings, the highway and the railway line. Such levels of flooding are likely to happen again. It is important to be prepared for flooding events that may not have happened within most people\u2019s living memory.<\/p>\n\n\n\n
