Riverine flooding information for areas south of Geeveston

Version 1.0 August 2024

若要更詳細地查看地圖，, 查看塔斯馬尼亞策略性洪水圖.

Low lying areas along the Huon River can be at risk of flooding if the Huon River has a major flood.

Parts of Dover and surrounding areas are subject to flash flooding from other waterways such as Dover Rivulet, Esperance River and Lune River if there is heavy local rain.

You are likely to experience flooding such as that shown in the maps at least once in your lifetime. Flash flooding means there is often little specific warning of flooding beyond forecasts for heavy rain or severe weather.

Even if your home is not inundated, you should be prepared for isolation plus potential power and telecommunications outages. Key access roads may be cut at Huonville, Geeveston and some other places during a major flood event. Travel in the area is likely to be difficult or impossible until roads are clear and safe. If you are safe at home or elsewhere, it is usually best you stay where you are until the flooding subsides, unless there is an emergency. If you need to evacuate, you should leave early, before flood waters rise.

Caves in the area can flood and heavy rainfall can cause cave instability.  Do not enter caves in the area if heavy rain is forecast.

Listen to ABC local radio 936AM for warnings and advice.

您有洪水風險嗎？

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

Dover and the areas south of Geeveston are exposed to weather systems from the West, South and East. The area often has heavy rain, and has had flooding before, for example in December 1995. Tasmanians need to be prepared for flood events that may not happen often, as well as the more minor flooding they may have experienced.

我應該做什麼？

• 檢查地圖，看看您的住宅或企業是否可能遭受洪水侵襲。.
• 評估您的住家或公司，並做好準備以盡量減少潛在的洪水損害。.
• 檢查您是否能在洪水期間安全地抵達家中、工作地點或學校。.
• Prepare a Home Emergency Plan. See 為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。. 
• 如果你可能被隔離且必須取得服務，你可能需要提早撤離。.

Avoid travel during floods.

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 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.

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

本局發佈 洪水警报、恶劣天气警报和/或雷暴警报，可能因强降雨引发山洪暴发每當 大雨is expected in an area. The time between the warning and heavy rain occurring can vary from an hour to 24 hours or more.

Whenever rain that may lead to flooding along the Huon River is expected, the Bureau will issue:

SES and the Bureau will issue warnings when the Huon River reaches the following levels.

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 as the river systems are too short.

雨量觀測 at Dover, Southport, Hartz Mountain, Mt Bobs, Cape Bruny and/or Maatsuyker Island can indicate possible flood risks. Given the very short warning times, you are encouraged to act on the predictive BoM warnings rather than wait for any flood alerts during rainfall.

這 Mt Koonya Radar is useful to be aware in real-time where heavy rainfall is falling.  Radar Rainfall estimates can also fill in gaps in areas where there are no rainfall stations.

洪水水位

While no two floods are the same, the following shows what you can expect at different flood levels around the area. Even if your property is not flooded, you need to think about access. The example rainfall to cause such an event is an example: other levels of rainfall can cause flooding depending on its intensity, duration and how wet the ground is beforehand and where the rain falls.

Huon River major flooding

If there is major flooding along the Huon River, and depending on the tides, there may be flooding in low-lying areas close to the river between Geeveston and Surveyors Bay. The Huon Highway may be inundated around Surges Creek, as well as areas further north such as at Huonville, and/or Geeveston if the Kermandie River floods.

A major flood on the Huon River means the river height is at least:

• 6 metres at Judbury and
• 4 metres at Huonville Bridge.

That level of flooding is approximately the level of the 2016 floods and there is about a 10% chance of such a flood happening any year.  Tasmanians need to be prepared for floods that have a 1% chance of happening every year.  In this level of flooding, the river height would be about:

• 9.5 meters at Judbury and
• 5.6 meters at Huonville Bridge.

Minor or Moderate flooding along the Huon River is unlikely to cause any significant impacts in the lower areas of the river south of Geeveston, unless there is a particularly high tide.

Flooding from other waterways

小範圍淹水

A minor flood can inundate low lying paddocks, orchards and other farmland.  Stock should be moved for their safety.  There may also be some flooding across some minor roads and parkland areas.

中度洪水

There is more extensive flooding of agricultural land and some buildings may be impacted to above floor height. Some properties may be isolated for a few hours as more minor roads become flooded.

嚴重洪水

There is at least a 2% chance in any year of major flooding along Dover Rivulet, the Esperance River, Lune River or other smaller waterways impacting Dover and surrounding communities. 

This level of flooding could be as a result of about 50mm of rain over 6 hours around Dover, for example. Depending on where the rain falls, this level of flooding is likely to

• Close the Huon Highway in several places
• Flood some properties in low lying areas on the northern side of Dover around Exters Road, Ida Road and also Slaughterhouse Road
• Flood some low-lying properties around Lune River and along Esperance River Road
• Isolate popular tourist places like Hastings Caves, Lune River, Ida Bay and Cockle Creek plus wilderness areas.

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

為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。. 

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

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。.

See for example the Huon Valley Good Neighbour project.

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.

Avoid travelling during and after storms

• 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.
