Riverine flooding information for the lower Mersey River and Kings Creek

Version 1.0 January 2026

要更详细地查看地图，, 查看塔斯马尼亚战略洪水地图.

Latrobe and surrounds are likely to be impacted by flooding at the Mersey River and Kings Creek.

• If there is heavy rain upstream in the Mersey River, flood waters may reach and impact Latrobe.
• If there is heavy rain over Latrobe itself, Kings Creek and other stormwater can also cause local flash flooding.

To help reduce flooding in the town, a flood levee and diversion system have recently been built. These are designed to lower the flood risk in parts of Latrobe. Areas inside the levee mitigated areas are expected to flood less often or not as deeply as before.

However, levees are not guaranteed to stop all flooding. SES recommends people evacuate levee protected areas in major flood events. Major flooding could see the levee overtop or fail. Major flooding has a 2% chance (2% Annual Exceedance Probability (AEP) of occurring in any year.  

If your property is outside the levee mitigated area, your flood risk has not changed. There is also some uncertainty about how the new infrastructure might affect flooding in other areas nearby. The maps show areas that are likely to be inundated and isolated in a flood.

In a major flood, roads in and around Latrobe will be cut before some areas are flooded. If you need to evacuate, you should leave early, before flood waters rise.

Go to www.TasALERT.com or listen to ABC local radio for warnings and advice.

Flood waters may isolate your home for several days. Even if your home is not flooded, you may not be able to access help if needed. You should have supplies for at least three days and prepare for power and telecommunications outages.

您有洪水风险吗？

Past major flooding events around Latrobe since the construction of hydro-electric dams upstream include:

• August 1970 – This major flood was one of the largest recorded floods of the Mersey River and caused extensive inundation and damage to local businesses.
• March 1977 – This flood caused 14 homes to be inundated.  Flooding was primarily due to flows in Kings Creek, not the Mersey River, so it occurred with much less warning than usual.
• June 2016 – Highest recorded flood at Latrobe.  121 properties were flooded, and there was significant damage to public infrastructure.
• October 2022 – This flood was similar in scale to the one in 1970, however people were better prepared.  Despite widespread inundation, losses were minimised.

Before the dams, there were flooding events in 1884, 1893, 1894, 1923, 1929, 1944 and 1952. 

Flood levels at Latrobe

While no two flood events are the same, the following table shows what you can expect for different flood levels around Latrobe. Even if your property is not flooded, you should think about access routes.

Minor flood

Rainfall likely to trigger this kind of flooding: 55-110mm/24hrs

River levels: 3.1m to 3.5m @ Mersey Rv at Latrobe Bridge river gauge

Likelihood off occurring in a year (AEP): 50% chance of occurring

Likely flood impacts: Flood water may cover low-lying areas. Farmland surrounding Latrobe is likely to be affected. Farm equipment and livestock in low-lying areas should be moved to higher ground. People living in very low-lying areas in and around Latrobe should be alert and stay informed in case conditions worsen.

中度洪水

Rainfall likely to trigger this kind of flooding: 85-150mm/24hrs

River levels: 3.6m to 3.9m @ Mersey Rv at Latrobe Bridge river gauge

Likelihood off occurring in a year (AEP): 10-20% chance of occurring

Flood impacts

Flood water will cover larger areas of land and enter some homes and other buildings.

Railton Road, Mersey Main Road, Coal Hill Road & Bells Parade may be flooded

In a high moderate flood water may enter houses & businesses in the low-lying areas of the town around:

• Mersey Main Road
• River Road/Twiss Street
• Shale Road
• Tarleton Road and
• Mersey Main Road

特大洪灾

Rainfall likely to trigger this kind of flooding: 85-150mm/24hrs

River levels: 4.0m+ @ Mersey Rv at Latrobe Bridge river gauge

Likelihood off occurring in a year (AEP): 2% chance of occurring

Flood impacts

Widespread flooding may cause significant flooding of homes, businesses and other buildings.

The Mersey River may flood large parts of the town west of the supermarket/Kings Park will likely be inundated.

Flooding from Kings Creek, will likely affected houses in the surrounding area.

Many properties will flood including residences & businesses in::

• Gilbert Street
• Victor Street
• Urquhart Lane
• Twiss Lane
• Twiss Street
• Madeline Street
• Last Street West
• Railton Road
• Shale Road
• Mersey Main Road
• Kobie Lane

Properties in Coal Hill Road, Ballahoo Road, Old Deloraine Road and Devil Road may be isolated for days.

我应该怎么做？

• Check the map to see whether your home or business is at risk of being flooded. If it is, you should have a plan for leaving during a flood event.
• Check if you can safely get to or from your home, work, or school during a flood. If you need to leave during a flood, make sure your route is safe or leave early before floodwaters rise. If you need to evacuate during a flood, make sure your route safe and think about:
  • where you would go
  • how you could get there
  • what you need to take.
• Prepare your home or business to minimise possible flood damage.
• Prepare a Home Emergency Plan. See 做好应急准备 – A guide for individuals and households to prepare for emergencies . 
• 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/managing/risk_management .  
• During a flood event, go to TasALERT.com or listen to ABC local radio to find out about evacuation centres or other places to shelter. 
• TasALERT’s risk ready tool also lets you check your property’s exposure to a range of hazards.

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

If you live in a low-lying area, your house may flood. Even if your home is safe, you may need to detour around flooded areas or your road access may be cut. Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe.

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 Bureau of Meteorology (the Bureau) issues a Flood Watch when predicted weather might cause floods in one or two days. A Flood Watch may:

• be for a specific area such as Latrobe, or
• be generalised such as for north-west river basins

The Bureau issues Minor, Moderate and Major flood warnings specifically for the Mersey River, including predicted flood height. The time between the warning and flooding occurring can vary from a few hours to one or two days.

Rainfall Monitoring and Observations

River levels and rainfall in the Mersey River catchment (including the Fisher River and Arm River) can be monitored on the Bureau of Meteorology website.  Go to www.bom.gov.au/tas/flood/northwestern.shtml

The N.W. Tasmania (West Takone) Radar is useful to be aware of where heavy rainfall is falling.  Radar Rainfall estimates can fill in gaps in areas where there are no rainfall stations. Go to: www.bom.gov.au/products/IDR523.loop.shtml .

洪水之前

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。.

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。.
• Do not turn on electricity or gas until it is tested by a licensed electrician or gas fitter for safety.
• 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。.
