Riverine and flash flooding flooding information for communities on the Derwent River and its tributaries around Bushy Park, Glenora, Plenty, Gretna and Hayes.

草稿 – 請將任何意見回覆至 ses@ses.tas.gov.au

Parts of Bushy Park, Macquarie Plains, Glenora, Plenty, Gretna, Hayes and surrounding areas are subject to flooding from the Derwent and/or its tributaries, such as the Styx River and the Plenty River.  The Derwent River and its tributaries may flood at the same time or at different times. Low lying areas may also be impacted by storm water runoff following local high rainfall events.

The maps show the estimated flood levels for widespread rain that has a 2%, 1% and 0.5% chance of happening any year (2%, 1% and 0.5% Annual Exceedance Probability (AEP)). You are likely to experience this level of flooding at least once in your lifetime. 

Widespread heavy rainfall in the Derwent catchment can cause widespread flooding particularly around Bushy Park and Glenora’s agricultural areas and nearby homes and other property.

Melting snow, rain on snow, the level of soil moisture and the dam levels can impact flood levels.  However, dam level management is not likely to have any significant impact during a major flood event.

Styx River flooding can impact agricultural land around Glenora and Bushy Park.

Flooding in the Plenty River can flood areas around Salmon Ponds, and properties near where the Plenty River joins the Derwent, particularly if the Derwent River is in flood.

您有洪水風險嗎？

The area has a long history of flooding.  The most significant flood since European settlement in 1960 flooded large areas of farmland, many homes and other buildings and isolated the area. Flooding also happened in 1916, 1922, 1923, 1924, 1946, 1947, 1948, 1951, 1952, 1953, 1958, 1962, 1970, 1971, 1974, 1975, 1980, 1988, 1991, 1994, 2007, 2009, 2011, 2016 and 2018.

It is important to be prepared for flooding events that may not have happened within most people’s living memory.

我應該做什麼？

• 請參考對面的地圖，了解您的住宅或商業場所是否可能在洪水期間面臨淹水風險。.
• 制定家庭緊急計畫，包括是否需要提前撤離以應對洪水、將去往何處以及需要攜帶什麼物品。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。. 
• 如果您在該地區設有公司，您應該制定一項包含洪水應對計劃。Business Tasmania 可以提供協助——請參閱 www.business.tas.gov.au/manage_a_business/ 
• 如果您需要在洪水期間撤離或返家，請務必確保路線安全。.
• 評估您的住宅或商業場所，了解需要採取哪些措施以做好準備，最大限度地減少水患可能造成的損害。.

像地圖上顯示的洪水，或者更糟的洪水，將會再次發生。沒有兩次洪水是相同的。.

如果您居住在低窪地區或靠近水道，您的房屋可能會被淹沒。即使您的住所安全，您也可能需要繞過淹水地區，或者您的道路通行可能會被阻斷。切勿駕車進入或身處洪水之中。道路和橋樑可能會被沖毀或不安全。洪水期間請避免出行。.

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 monitors rainfall and river levels in the upper reaches of the Derwent River. They issue flood warnings when river levels are likely to reach the following heights. SES works closely with the Bureau to provide timely warnings where possible.

水位計	警報	未成年	適中	主修
歐斯河在阿什頓	2.4公尺	2.4公尺	3.2	4.5
歐澤河 3B 堰		3.0	3.7	4.3
Clyde River at Bothwell	0.9m	2.0m	3.0	4.0
Styx River at Bruces Bridge		2.0m	不適用	不適用
德文特河，梅多班克水壩下方	4.1 百萬	4.1 百萬	6.1公尺	7.3米
Derwent River at Macquarie Plains	4.0m	4.0m	5.0m	6.7m
Plenty River at Feilton		2.8m	不適用	不適用
Derwent River at New Norfolk		2.0m (2.3m estimated 50% AEP)	4.0m (4.31m estimated 10%AEP)	6.0 (6.3m  estimated 1% AEP)

Notes

• % AEP (Annual Exceedance Probability) is estimated and only a rough guide. Rainfall levels and so flood levels can differ greatly across the catchment in a flooding event. More precise estimates of gauge and flood warning levels is a work in progress.
• A major level in the upper catchment may not translate to a major level at New Norfolk if there is not high rainfall in other parts of the catchment.
• While previously the 1960 flood was considered about a 0.75%AEP event (1 in 150 year event), more recent information suggests the event was more rare, that is, with less than a 0.5% chance of happening any year.

For information on flood warnings in the Lachlan River see the related Lachlan River Flood Guide.  In summary, there are no water level gauges on this river – the short catchment does not give enough time to issue a warning before flooding arrives.  Keep an eye on rainfall on kunanyi/ the Wellington Range.

Flood levels around the Derwent River

雖然沒有兩次洪水是完全一樣的，但以下描述了如果您所在地區發生洪水，可能發生的情況。即使您的房產沒有被淹沒，您仍需要考慮進出問題。.

可能導致此類事件的降雨量僅為示例。其他降雨量也可能導致洪水，具體取決於

• 雨落之處
• 雨有多大
• 雨會下多久，而且
• 地面事先有多濕。.

融化的雪水也可能导致洪水。.

小範圍淹水

Derwent River levels at Macquarie Plains are at least 4m and/or Styx River at Bruces Bridge at least 2m and/or the Plenty River at Feilton is at least 2.8m

• Water spills over riverbanks and covers nearby low-lying areas. 
• Agricultural and horticultural land on river flats may be at risk.  Livestock should be moved from these areas.

中度洪水

River levels at Macquarie Plains are at least 5m

• There is more extended and deeper flooding of agricultural land along river flats with some stock losses if not moved. There may be damage to fences and equipment such as pumps.
• Some low lying areas of the Lyell Highway and Glenora Road may begin to flood
• Flooding may reach above floor heights of some low-lying houses and other buildings.
• 部分低水位橋樑上方的房產可能會變得孤立。.

嚴重洪水

Derwent River levels at Macquarie Plains are at least 6.7m

Widespread heavy rainfall across the catchment that has a 1- 2% chance or less of happening can cause major flooding.  This level of rainfall might be for example more than:

• 53mm over 6 hours
• 73mm over 12 hours
• 101 mm over 24 hours
• 132mm over 48 hours

Note the level of flooding can depend on many factors, such as where the rain falls and how widespread it is, and how wet the catchment is beforehand.  Areas that are likely to be flooded from Derwent River flooding include on the Southwest side of the river:.

• The Bushy Park Roadhouse and surrounds
• Bushy Park to the north of Gordon River Rd
• Salmon Ponds and surrounds
• Parts of the Plenty Valley Road at Fielton and some low-lying sheds
• Glenora Road near Raynor’s Corner and nearby low lying properties

The Styx River can also cause flooding in agricultural land around Glenora and Bushy Park.

Areas at risk of inundation on the Northeast side of the river include:

• Marked Hill Road, Clarendon Road, Askrigg Road and the Lyell Highway near Gretna
• Several areas of the Lyell Highway at Hayes, plus nearby surrounding properties.

The area is likely to become isolated from New Norfolk and upstream areas due to flooding across the Lyell Highway and Glenora Road. Other potential areas of isolation are:

• SE New Norfolk/ Brookside
• New Norfolk CBD south side Derwent
• New Norfolk north side river, Lawitta, Magra
• Pulpit Rock Road
• Glenora Road West of New Norfolk
• Glenfern Road and surrounds

If flooding levels reach the same heights as the 1960 floods in New Norfolk (6.8m), flooding in the areas already listed will be deeper, and could spread to the following areas:

• Glenora
• Bushy Park/ Uxbridge Rd
• Glenora Rd various areas
• Plenty
• Rosegarland
• Hayes

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

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。.

請參見例如 荷恩谷鄰里互助計畫.

期間

5. 保持最新

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. 保持安全

• 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
• 胡昂谷議會關於準備緊急寵物計畫的建議
• 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.
