Riverine flooding information for the South Esk River, Macquarie River and Back Creek

要更详细地查看地图，, 查看塔斯马尼亚战略洪水地图.

Longford can have riverine flooding from the South Esk River, Macquarie River and Back Creek. The levee system was constructed to protect Longford and mitigate against rare flooding events of the South Esk River.

The map shows the expected Major Flood levels in the Longford region. This level of event has about a 1% chance of happening any year (1% Annual Exceedance Probability (AEP). You are likely to experience a flood of this size in your lifetime.

A 1% AEP event is the limit of flood mitigation provided by the Longford levee system. Above this level there will start to be flooding within the levee protected area.
In the event of levee gate closure at Tannery Road access to the north is closed, and some streets off Wellington Street to the east. This will include the installation of some temporary levee structures. An alternative flood access plan will become activated during a major flooding event.

During a Major flooding event there are three alternative routes that can be used according to the height of the floodwaters, and closure status of the levees:

• Route 1 (Green) – Before closure of Illawarra Road vehicles can travel out of Longford via Wilmores Lane (Opposite Austral Bricks), turn right onto Bishopsbourne Road and turn right onto Illawarra road towards Perth, or left to the Bass Highway. This route may be closed considerably earlier than the flooding risk by Tasmania Police.
• Route 2 (Purple) – When Illawarra Road to the east of the Longford town entrance becomes closed, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and turn left onto Illawarra Road and travel north to the Bass Highway.
• Route 3 (Orange) – When Illawarra Road is closed to the east and west of the town entrance, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and continue along the road to Carrick (Meander Valley Road), and then onto to the Bass Highway.

Even if your home is not inundated, you may be isolated for several days. You should have supplies for up to three days and be prepared for power and telecommunications outages. Note if you are isolated, you may not be able to access medical or other help if needed.

您有洪水风险吗？

Longford has a long history of flood events. Examples of past flooding events around Longford include the following.

• The first recorded major flooding event for Longford was during 1823, with extensive flooding reported across the Northern Midlands region.
• The major flood event of 1863 was reported as a larger event than 1929 flood event.
• The 1929 flood is the highest Major flood level officially recorded with extensive flooding of Longford. This was an estimated 1% AEP flood event.
• The 1969 flood recorded extensive flooding and was before the modern levee structure. This was an estimated 3% AEP flood event.
• During the 2011 and 2016 flood events the Northern Midlands Council closed some levees as a precaution.

我应该怎么做？

• Check the map to see whether your home or business is likely to be at risk during a flood.
• Check if you might not be able to safely get to your home, work, or school during a flood.
• 准备家庭应急计划。考虑是否需要在洪水来临前撤离。参见 做好应急准备 – 个人和家庭应急准备指南。. 
• 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。.

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

BoM 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 Longford.
• be for the South Esk River, or Macquarie River.
• be generalised such as for the Central North forecast area.

BoM issues a Severe Weather Warning for very heavy rain that may lead to flash floodingwhenever this weather is occurring or is expected in an area. The amount of time between the warning and the arrival of the heavy rain can vary from an hour to 24 hours or sometimes more.

BoM issues Flood Warnings with specific flood heightsfor the South Esk River at Longford gauging site with warnings of flood heights. Flood warnings can be issued for Minor (3.5m), Moderate (5.0m) and Major (7.0m) flood levels.

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

If you live in a low-lying area you may be at risk of flooding. Even if your home is safe, you may need to detour around flooded areas. Never drive through or enter flood waters.

Knowing what to do can save your life and help protect your property. Preparing a Home Emergency Plan is one of the best ways to prepare.

Include weather and rainfall triggers for action in your Home Emergency Plan.

了解风险，做好准备，尽可能降低风险，与他人联系，保持警惕，并安全行事。.

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

定期测试收音机和手电筒里的电池。.

3. 尽可能降低洪水风险

• 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. 与他人联系

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。.

于

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。. 

• 塔斯警报 
• 您当地的ABC广播电台 或
• 这 气象局 网站.

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

• RSPCA 应急动物准备指南
• Huon Valley Council’s advice on preparing an emergency pet plan
• 这 初级生产者农场防洪准备工具包.

避免在风暴期间和风暴过后出行

• 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.
