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.

您有洪水風險嗎?

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.

我應該做什麼?

  • 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 為緊急情況做好準備 – 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.

知道該怎麼做可以拯救你的生命並保護你的財產。制定家庭緊急計畫是最好的準備方法之一。決定天氣和降雨的觸發條件,以便採取行動。.

中央氣象局預報、警報與觀測

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 .

了解你的風險,做好準備,盡可能降低風險,與他人聯繫,保持警惕並安全行動。.

洪水之前

1. 認識你的風險

塔斯馬尼亞經常發生洪水,可能造成廣泛且嚴重的損害。在過去 200 年裡,塔斯馬尼亞有 78 人死於與洪水相關的事件。本指南旨在幫助您了解您所在地區的洪水風險。.

2. 準備您的家戶

制定包含風暴和洪水應變計畫

思考一下在風暴或洪水來襲時你會怎麼做,意味著你準備得更充分,每個人都會更安全。制定一個家庭中的每個人都理解的緊急計畫。有檢查表可以幫助你思考你的計畫——請參閱 為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。. 
定期檢查您的計劃,並讓家中的每個人都設想一次可能影響您家的洪水情況來進行測試。.

準備一個緊急救生包

準備好了

  • 電池供電的收音機和手電筒,備用電池
  • 重要資訊,例如您的緊急應變計畫
  • 緊急電話號碼列表
  • 食物和水
  • 急救箱
  • 橡膠手套或堅固的皮革手套

需要時打包

  • 暖和的衣服、結實的鞋子或靴子
  • 藥品、眼鏡或其他必需品
  • 手機和充電器
  • 寵物食品和他們需要的任何其他東西
  • 照片和特別紀念品

3. 在可能的情況下,降低您遭受洪水侵襲的風險

  • 在購買、維護或開發房地產時,請考慮風暴、洪水和其他災害。.
  • 修剪或移除您家中、商家或您家附近有電力線的樹木和樹枝。.
  • 保持您的排水溝和排水管暢通。.

4. 與他人建立聯繫

認識你的鄰居並參與你的社區。一個緊密的社區,在緊急情況下更安全、更有韌性,並有助於每個人在事後更好地恢復。檢查家人和鄰居是否安全,並了解正在發生的事情。.

期間

5. Keep up to date

隨時留意周遭狀況。定期查看天氣預報、觀測數據和警報。. 

6. Act Safe

  • 監督兒童.
  • 為可能的停電、停水或斷網做好準備。.
  • 檢查您的緊急救助包是否已準備就緒。.
  • 切勿靠近淹水區域,例如排水溝。. 永不 在洪水中有行走、玩耍、骑行或开车。你無法確定水下有什麼,或水有多深、流速有多快。20公分的湍急的洪水就很容易將人沖走並淹死。洪水可能很危險。.

您的房屋可能發生淹水時

  • 將家居物品放在高處,以盡量減少潛在損壞。.
  • 如果安全的話,請關閉水電和瓦斯。. 
  • 一種防止污水倒灌回屋內的好方法是將沙包放入塑膠袋中,然後用它們來堵塞馬桶、蓋住排水孔和水槽。.
  • 趁你還能安全脫困時趕快離開。.

如果你需要疏散

  • 請遵循 SES / 塔斯馬尼亞警方的建議。.  
  • 帶上你的緊急求生包。. 
  • 前往朋友或家人較安全的地方,或前往疏散中心。. 
  • 讓別人知道你去了哪裡。.

照顧好你的動物

在緊急情況下,您有責任照顧您的動物。如果您有寵物和其他動物,在洪水或其他緊急情況下,疏散的時間會更長。在洪水可能上漲之前,請及時將牲畜移離易受洪水影響的地區。更多資訊請參閱

請避免在風暴期間和風暴之後旅行

  • 不要去觀光。觀光客會延誤緊急服務並造成事故。.
  • 注意危險,例如
    • 路面积水
    • 損壞的電力線
    • 山崩
    • 損壞的道路
    • 倒下的樹木或屋頂鐵片。.
  • 切勿駕車通過淹水區域。洪水中的大多數死亡和救援事件都與駕車通過淹水區域有關。.
  • 緩慢行駛,並在不受洪水影響的道路上打開頭燈。.

之後

  • 請持續收聽 ABC 地方電台的最新消息、道路重新開放、社區會議等資訊。.
  • 如果您離開家,請勿在聯邦緊急事務局 (SES) 或塔斯馬尼亞警方告知您安全之前回家。.
  • 注意道路上的危險,例如路面上的泥沙或碎屑、道路/橋樑損壞以及正在進行清理和修復工作的工人。.

如果您的房屋已受損

  • 在檢查損壞時,請待在地面。小心掉落的樹木、碎玻璃、鬆動的屋頂或其它危險物品。.
  • 穿著堅固的靴子、手套和防護服。. 
  • 請使用手電筒,切勿在受洪水影響的建築物內使用火柴或蠟燭。. 
  • 將所有飲用水煮沸,直到被告知自來水再次安全為止。.
  • Do not turn on electricity or gas until it is tested by a licensed electrician or gas fitter for safety.
  • 如果您的房屋受損,需要暫時住在其他地方,請攜帶您的緊急應變包和寵物一同前往。
  • 如安全,請拍攝任何損壞的照片,並聯繫您的保險公司。.
  • 監督兒童.
  • 檢查鄰居是否安好。.

免責聲明

這些地圖顯示了跨流域的持續降雨量所造成的潛在洪水風險,例如 1% 年超越機率 (AEP)。在洪水事件中,降雨量在流域內的分布可能更不均勻,因此這些洪水地圖僅供參考。已繪製的洪水風險區域顯示淹水機率較高。其他區域的淹水機率較低,但在嚴重且罕見的事件(機率低於 1% AEP)中,其他較低的區域也可能面臨淹水風險。.
