Riverine and flash flooding information for areas around Sandy Bay Rivulet and nearby minor waterways

Version 1.0 November 2025

To see the maps in more detail, go to www.ses.tas.gov.au/floodmaps/ 或 www.hobartcity.com.au/City-services/Stormwater-and-urban-waterways/Flood-risk-and-maps .

Tasmanians need to prepare for flood events that may not happen often as well as the minor flooding they may have experienced.

If you live, work or often visit Sandy Bay or surrounding areas, it is important you understand what a flood can look like so you can prepare. There is likely to be a flood that causes significant damage in the area at least once in your lifetime.

When there is heavy intense rain the Sandy Bay Rivulet can flood low-lying roadways and properties around

• Lower Waterworks Road/ Lynton Avenue/ Davey Place
• Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
• Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
• Quayle Street / Balmoral Street area
• Marieville Esplanade and waterside areas.

Other minor waterways or overland flow can impact

• Lower Duke Street/ Sandy Bay Road / Margaret Street area
• Proctors Road/ UTAS Sandy Bay Campus
• Lambert Rivulet surrounds,
• Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
• Lower Sandy Bay / Sandown Park/ Nutgrove area
• Sandy Bay Road to the north of Cartright Reserve
• Parts of Hobart are prone to flash flooding, depending on how rain falls across kunanyi/ Mount Wellington. This means there can be little warning before waterways flood.
• There can also be stormwater run-off in other places if there is heavy rain. This can be difficult to predict.
• Areas near the waterfront are also affected by tides and coastal inundation, especially around Marieville Esplanade.

Flooding can isolate properties for a short time, depending on where the rain falls and how heavy it is. Even if your home is not flooded you should prepare for

• isolation
• potential power and telecommunications outages.

Waterways in the area are short, so flooding is likely to be for hours rather than days after rain stops. If you are safe at home or elsewhere, it is usually best to stay where you are until the flooding subsides. If you need to evacuate, pick up children from school or travel for some other reason, you should do so early, before flood waters rise.

The maps in this guide show the level of flooding that has a 1% chance of happening any year (Annual Exceedance Probability (AEP)) due to riverine flooding from Sandy Bay Rivulet and nearby minor waterways.

Check TasALERT.com or listen to ABC local radio Hobart 90.5FM or 936 AM for warnings and advice.

您有洪水風險嗎？

Example past flooding events around Hobart include:

• May 2018 – The Southern Tasmanian Extreme Weather Event caused flooding around Hobart. There was 236mm of rain on Kunanyi/ Mount Wellington in 24 hours. 
• April 1960 – About 200mm of rain over 3 days and caused damage across Hobart.
• June 1947 – Two separate flooding events impacted the Hobart area.

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. See alert.tas.gov.au/get-ready/risk-ready/

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

If you live in a low-lying area or near a watercourse, 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. Avoid travel during floods.

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。.

Bureau of Meteorology (BoM) Forecasts, Warnings, and Observations

Whenever 大雨 is expected in an area, the Bureau issues

• a Flood Watch
• 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.

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

這 Mt Koonya Radar is useful to see when and where heavy rainfall is falling.

洪水水位

While no two floods are the same, the following describes what you can expect at different flood levels around the area. Even if your property is not flooded, you need to think about access. Different levels of rainfall can cause flooding depending on its

• intensity
• duration
• how wet the ground is beforehand, and
• where the rain falls.

In minor flood events

• Riverine flood water and storm water run-off may reach some building floor levels and impact low-lying paths, parks and backyards.

中度洪水

• May mean water starts to enter some homes and other buildings
• There may be water across some key routes, such as Sandy Bay Road and Churchill Avenue/ Regent Street.
• Traffic is likely to become gridlocked in these conditions.

A major flood event

• May be for example due to heavy rainfall in the river catchment of about
  • 17mm or more in half an hour
  • 36mm or more in 3 hours
  • 51mm or more in 6 hours (5% AEP @ Hobart)
• Is likely to cause flooding over major thoroughfares in places, cutting access in some places. Traffic conditions are likely to be difficult.
• May isolate many properties for short periods. Flooding should quickly dissipate once rain stops.
• May inundate many low-lying areas. Flooding is likely to be more hazardous around:
  • Lower Waterworks Road/ Lynton Avenue/ Davey Place
  • Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
  • Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
  • Quayle Street / Balmoral Street area
  • Marieville Esplanade and waterside areas.
  • Lower Duke Street/ Sandy Bay Road / Margaret Street area
  • Proctors Road/ UTAS Sandy Bay Campus
  • Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
  • Lower Sandy Bay / Sandown Park/ Nutgrove area

• Sandy Bay Road to the north of Cartright Reserve
• May include storm water run-off impacting other areas.
• Increase landslip and coastal erosion risks.

Weather systems causing such rainfall can also often cause coastal storm surge, particularly at high tide.

Know your risk, prepare, reduce risk where you can, connect with others, keep up to date and act safe.

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。.

TasALERT’s risk ready tool lets you check your property’s exposure to a range of hazards. See alert.tas.gov.au/get-ready/risk-ready/

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

定期測試收音機和手電筒的電池。.

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。. 

• 塔斯警報 
• 您當地的 ABC 電台 或
• 這 氣象局 網站.

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

• RSPCA 應對緊急情況動物的指南
• Huon Valley Council’s advice on preparing an emergency pet plan
• 這 主要生產者農場洪水準備工具箱.

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。.
• 在經註冊電工或燃氣技師測試安全之前，請勿開啟電力或燃氣。.
• 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

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.
