Riverine flooding information for the Leven River

Version 1.0 September 2023

Gunns Plains (North) Flood Map –  To see the maps in more detail, 查看塔斯马尼亚战略洪水地图.

The Leven River can cause flooding in and around Gunns Plains, Loongana & Foggs (Purtons) Flats. The maps show where a flood is likely to reach. The darker blue areas are the most likely to flood.

An extensive network of underground caves and streams exists in Gunns Plains & Loongana. Flooding in these streams can cause sinkholes to appear unexpectedly, or underground flood water can make it to the surface and cause damage in areas not usually prone to flooding.

In a major flood, roads in and around Gunns Plains and Loongana 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 recent flooding events around Gunns Plains and Loongana include:

  • January 2011 – This flood was unusual in that it occurred in summer and due to rainfall mostly in the mid to lower catchment, catching many by surprise. Severe damage was caused through Gunns Plains and 2 significant bridges over the Leven River were washed away. Some residents were isolated for weeks.
  • June 2016 – Highest recorded flood in the Leven River.  Some businesses were flooded, and there was significant damage to public infrastructure including roads and bridges.
  • October 2022 –Severe damage occurred to some businesses as well as roads and other infrastructure. Bridge damage and several landslips around Gunns Plains and Loongana caused extended road closures and some residents to be isolated for many days.
  • June 2023 – With as little as 80mm of rain falling overnight, Marshalls Road and South Riana Road were inundated.  Wings Wildlife Park was isolated and some cattle in Gunns Plains were surrounded by floodwater and may have been lost if the floodwater had risen further.

我应该怎么做？

  • Check the map to see whether your home or business could flood or be isolated.
  • 洪水期间，检查您是否能够安全地到达家、工作地点或学校。.
  • Prepare a Home Emergency Plan. See 做好应急准备 – 个人和家庭应急准备指南。. 
  • If you are a primary producer, the Farm Flood Readiness Kit provides advice on preparing for a flood to help protect your
  • If you will be isolated you may need to evacuate early.
  • 评估您的住宅或企业，并做好准备以最大程度地减少潜在的洪水损害。.
  • If you are camping in a flood prone area, make sure you stay informed and move to higher ground early if a flood is likely.

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。.

Forecasts, Warnings, and Observations

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 Gunns Plains, or
  • be generalised such as for north-west river basins

The Bureau of Meteorology does not provide a specific flood warning for the Leven River.

Rainfall Monitoring and Observations

Whilst the Leven River catchment has no sub-daily Bureau of Meteorology rainfall stations, rainfall in surrounding areas can provide a good idea of what rain is falling in the upper catchment of the Leven River.  Rainfall at Lake Gardiner and Waratah can be monitored on the Hydro Tasmania website. Rainfall at Sheffield can be monitored on the Bureau website.

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: http://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

准备好了

电池供电的收音机和手电筒，备用电池

重要信息，例如您的应急计划

紧急电话号码列表

食物和水

急救箱

橡胶或结实的皮革手套

视情况打包

保暖衣物、结实的鞋子或靴子

药品、眼镜或其他必需品

手机和充电器

宠物食品以及它们所需的其他任何物品

照片和特别的纪念品

重要文件，例如
– insurance papers
– passports and
– birth certificates

定期测试收音机和手电筒里的电池。.

3. Reduce your risk from flooding where you can

  • 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. Connect with others

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。. 

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

Avoid travelling during and after storms

  • 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.
