The Huon River and its tributaries can flood low lying properties above Huonville/ Ranelagh and isolate some areas. 

Parts of Glen Huon Road and Glen Huon are prone to flooding, as are many minor roads around the area.

Areas upstream from Judbury and areas south of the river may become isolated during a major flood.

For those travelling in the area, Rivers Edge campground can flood and may become isolated in major flood events, and the Tahune area may become isolated in moderate to major flood events.

The maps show the expected flood level around the upper Huon catchment that has a 1% chance of happening any year (1% annual exceedance probability (AEP)). You are likely to experience a flood of this size at least once in your lifetime.

Heavy rain in the South West wilderness can cause the Huon River to flood even if there is little rain around people’s homes in the Huon Valley. Rapid snowmelt sometimes increases Huon River flooding. High rainfall lower in the Huon River catchment and its tributaries can also add to flooding. Huon River tributaries such as the Russell River and the Arve River can also flood, depending on where rain falls.

Storm water run-off can also impact properties when there is very heavy local rain.

Edgar and Scotts Peak Dam have minimal impacts on Huon River flood levels.

您有洪水风险吗？

The Huon Valley has a long history of major flooding, including in 1901, 1947, 1958, 1960, 1975, 1996, 2016 and 2022. The area often has minor flooding.

我应该怎么做？

• Check the map opposite to see whether your home or business is likely to be at risk of flooding during a flood.
• Prepare a Home Emergency Plan, including whether you need to evacuate in advance of a flood, where you will go and what you need to take. See 做好应急准备 – 个人和家庭应急准备指南。. 
• If you have a business in the area, you should have a plan that covers flooding.  Business Tasmania can help– see www.business.tas.gov.au/manage_a_business/ 
• If you need to evacuate or return home during a flood, make sure your route is safe.
• Asses your home or business and know what you need to do to prepare it to minimise possible damage from water inundation.

Floods like the one shown on the map, or worse, will occur again. No two floods are the same.

如果您住在低洼地区或靠近水道，您的房屋可能会被淹没。即使您的家是安全的，您也可能需要绕过洪水地区，或者您的道路通行可能会受到阻碍。切勿驾车进入或进入洪水区域。道路和桥梁可能被冲毁或不安全。请避免在洪水期间出行。.

了解该怎么做可以拯救你的生命并帮助保护你的财产。制定家庭应急计划是准备工作的最佳方法之一。决定天气和降雨触发条件，以便知道何时采取行动。.

澳大利亚气象局天气预报、警告和观测

The Huon River has several real-time river level gauges and a network of rainfall gauges that can support flood warnings.  Floodwater at Judbury generally takes a couple of hours to reach Huonville. Monitor rainfall totals and river rises at www.bom.gov.au/tas/flood/ .

Whenever there may be rain that leads to flooding along the Huon River the Bureau will issue:

• A Flood Watch – a “heads up” early advice of forecast weather that may lead to flooding.
• A Flood Warning – predicting when flooding is likely to develop at the gauge locations. These warnings may

River gauges	Alert	Minor	Moderate	Major
Huon River at Harrison’s Opening	5.0	5.0	n/a	n/a
Huon River at Tahune Bridge		4.0	5.0	6.3
Huon River at Judbury	3.0	4.0	5.3	6.0
Huon River at Huonville	2.5	3.0	3.6	4.0

There are no formal warning levels for other waterways in the area.

Whenever 大雨 is expected in an area that may lead to flooding, the Bureau issues

• Severe Weather Warning and/or
• Thunderstorm Warning for heavy rainfall that may lead to flash flooding.

The time between the warning and heavy rain falling can vary from an hour to 24 hours or more. It is best to act on the warnings from the Bureau of Meteorology rather than wait for local flooding alerts around Mountain River and Skinners Creek.

Tracking Rainfall on Kunanyi/ Mount Wellington can help predict flooding around Mountain River. Go to www.bom.gov.au/tas/ .

这 Mt Koonya Radar is useful to see when and where heavy rainfall is falling and is available on the BOM Weather app and website.

Download BOM Weather app and set your location to receive push notifications of warnings (more details at www.bom.gov.au/app/) .

Listen to ABC 936AM or go to tasalert.com for warnings.

Flood levels around the Huon River

While no two floods are the same, the following table shows what is likely to happen if there is flooding around Mountain River. Even if your property is not flooded, you need to think about access.

The rainfall amounts that might cause such an event are examples. Other levels of rainfall can cause flooding depending on

• where the rain falls
• how heavy the rain is
• how long the rain lasts, and
• how wet the ground is beforehand.

Minor flooding (Above 3m at Tahune, 4m at Judbury)

• Water spills over riverbanks and covers nearby low-lying areas.  Agricultural and horticultural land on river flats may be at risk.  Livestock should be moved from these areas.
• There may be some flooding of back roads or forestry roads, tracks and low level bridges, for example, Southwood Rd and Upper SheOak Road.
• Some low-lying properties may have flooding around buildings below floor level.

Moderate flooding (above 5m at Tahune, 5.3m at Judbury)

• There is more extended and deeper flooding of agricultural and horticultural land along the river flats with some stock losses if not moved. There may be damage to fences.
• There is likely to be more extensive flooding in low-lying sections of minor roads, including for example Charlies Road as well as Lorkins Rd, Southwood Road and SheOak Road.
• Flooding may reach above floor heights of some low-lying houses and other buildings,
• Some properties on minor roads above low-lying waterway crossings may become isolated.

Major flooding (Above 6.3m at Tahune, 6m at Judbury, starting from about a 5-10% chance of happening any year)

This type of event is similar to the 2016 flood event, but can differ depending on where rain falls.

• Parts of Glen Huon Road west from Huonville Bridge and surrounding low-lying properties begin to flood. The Huonville Golf Club begins to flood.
• The Huon Highway at Huonville is likely cut, isolating areas on the south side of the river that cannot be accessed via Judbury.
• Depending on where heavy rain falls, the Huon Highway south of Grove may be inundated for a short time.
• Low lying properties along the Huon River flood plain and possibly other minor waterways are at risk of being flooded above floor level. It may be necessary to evacuate some dwellings.
• Lonnavale Road at Judds Creek and Russell River crossings plus the campground at Lonnavale flood, isolating surrounding properties.
• Tahune Airwalk and surrounds may be isolated.
• Many back roads have areas that are flooded.
• The North Huon Road is not prone to flooding, but there if there is heavy rain, there are risks of fallen trees, landslides and hazardous driving conditions anywhere.
• While the Judbury Bridge may not be inundated, the approaches to the bridge may be.
• Many minor waterway crossings may be impassable due to flooding or should be considered hazardous. This can isolate areas above.
• There is likely to be crop and stock loss unless the stock are moved to higher ground.

Major flooding (About 9.5m at Judbury, about a 1% chance of happening any year)

The Huon Valley has not experienced this level of event in recent years. However, everybody should be prepared for it.  Parts of northern Tasmania have had this level of event several times in the past 10 years, and the chance of such events happening is increasing with climate change. Note many of these impacts will start in less severe events, for example those with a 5% or 2% chance of happening any year. In addition to the impacts listed above:

• There is extensive flooding along Glen Huon Road and low-lying properties.
• Many low-lying areas along back roads and forestry roads have high levels of flooding, including the Arve River picnic ground and Keoghs Creek Nature Trail.
• Lonnavale is likely to be isolated, with flood risks to low-lying properties to above floor height.
• Parts of Judbury may be flooded, including Calvert Park and some properties near Judds Creek.

While North Huon Road is largely not prone to flooding, there may be water over the road at the Call Creek crossing between Waggs Gully Road and Browns Road.

了解风险，做好准备，尽可能降低风险，与他人联系，保持警惕，并安全行事。.

洪水之前

做好应急准备 – 个人和家庭应急准备指南。. 

了解您的风险

塔斯马尼亚州经常发生洪水，可能造成广泛而重大的损失。在过去的 200 年里，塔斯马尼亚州有 78 人死于与洪水有关的事故。本指南旨在帮助您了解您所在地区的洪水风险。.

2. 准备您的家庭

制定涵盖风暴和洪水的应急计划

考虑一下在风暴或洪水来临时你会怎么做，这意味着你会有更好的准备，每个人都会更安全。制定一个你的家庭成员都明白的应急计划。有一些清单可以帮助你完善你的计划——请看 做好应急准备 – 个人和家庭应急准备指南。.
定期检查您的计划，并让家中的每一位成员都模拟可能影响您家庭的洪水场景进行演练。.

准备一个应急包

定期测试收音机和手电筒里的电池。.

3. 尽可能降低洪水风险

• 在购买、维护或开发房产时，请考虑风暴、洪水和其他危险。.
• 修剪或移除您家中、商铺上方或您物业附近电线上方的树木和树枝。.
• 保持雨水槽和排水沟畅通。.

4. 与他人联系

认识你的邻居并参与社区活动。一个联系紧密的社区在紧急情况下更安全、更有韧性，并且有助于每个人在事后更好地恢复。检查家人和邻居是否安全，是否了解正在发生的情况。.

See for example the Huon Valley Good Neighbour project.

5. Keep up to date

留意周围发生的事情。定期查看预报、观测和警报。. 

• 塔斯警报 
• 您当地的ABC广播电台 或
• 这 气象局 网站.

6. Act Safe

• 看管好孩子。.
• 为应对可能的电力、供水或网络中断做好准备。.
• 检查您的应急包是否已准备好。.
• 避开积水区域，如排水沟。. 永不 在洪水期间徒步、玩耍、骑车或驾车。您无法分辨水下有什么，也无法判断水深或水流速度。在仅 20 厘米的快速流动的水中，很容易被冲走并溺水。洪水可能很危险。.

当地面发生洪水时

• 将家用物品放在高处以最大程度地减少可能的损坏。.
• 如果安全的话，请关闭水电煤气。. 
• 一种防止污水倒灌回家的好方法是将沙袋放入塑料袋中，然后用它们堵住马桶、覆盖排水管和水槽。.
• 趁还能安全离开就走。.

如果您需要撤离

• 遵循 SES / 塔斯马尼亚警方 的建议。.  
• 带上你的应急包。. 
• 去安全地点或避难中心与亲友会合。. 
• 让别人知道你去了哪里。.

照顾好您的动物

在紧急情况下，您有责任照顾好您的动物。如果您有宠物和其他动物，在洪水或其他紧急情况下疏散需要更长的时间。在洪水可能上涨之前，将牲畜转移到易受洪水影响的地区。欲了解更多信息，请参阅

• RSPCA 应急动物准备指南
• Huon Valley Council’s advice on preparing an emergency pet plan
• 这 初级生产者农场防洪准备工具包.

避免在风暴期间和风暴过后出行

• 不要去观光。游客会延误紧急服务并造成事故。.
• 注意诸如
  • 路面积水
  • 受损的电力线
  • 山体滑坡
  • 损坏的道路
  • 倒下的树木或屋面板。.
• 切勿冒险涉水。洪水中的大多数死亡和救援事件都与驾车涉水有关。.
• 在未受洪水影响的路段，请慢行并打开车头灯。.

之后

• 请继续收听 ABC 本地广播电台的最新消息、道路重新开放信息、社区会议等。.
• 如果您离开了家，在紧急事务管理署（SES）或塔斯马尼亚警方告知您可以安全返回之前，请勿回家。.
• 注意道路危险，例如路面上的泥土或碎屑、损坏的道路/桥梁以及正在进行清理和维修的工作人员。.

如果您的房屋遭到损坏

• 在检查损坏时，请留在地面。注意倒下的树木、碎玻璃、松动的屋顶或其他危险。.
• 穿结实的靴子、手套和防护服。. 
• 在受洪水影响的建筑物内部，请使用手电筒，切勿使用火柴或蜡烛。. 
• 饮用水必须煮沸，直到被告知自来水安全为止。.
• 在经过持证电工或燃气技师安全检测前，请勿开启电源或燃气。.
• 如果您的房屋受损，需要住到别处，请带上您的应急包和宠物。
• 如果安全，请拍摄任何损坏的照片并联系您的保险公司。.
• 看管好孩子。.
• 检查邻居是否安好。.

免责声明

The maps show potential flooding risks from consistent levels of rainfall across catchments, such as a 1% Annual Exceedance Probability (AEP).  In flooding events, rainfall is likely to be more inconsistent across a catchment, so these flood maps should be considered indicative only.  The mapped areas of flood risk show higher probability of inundation. Other areas have lower probability of flooding, but in severe and rare events (rarer than 1%AEP), other lower areas may be also at risk of inundation.
