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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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:<\/p>\n\n\n\n

    \n
  • Route 1 (Green)<\/strong> \u2013 Before closure of Illawarra Road<\/strong> 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.<\/strong><\/li>\n\n\n\n
  • Route 2 (Purple)<\/strong> \u2013 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.<\/li>\n\n\n\n
  • Route 3 (Orange<\/strong>) \u2013 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.<\/li>\n<\/ul>\n\n\n\n

    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.<\/p>\n\n\n\n

    Longford has a long history of flood events. Examples of past flooding events around Longford include the following.<\/p>\n\n\n\n

      \n
    • The first recorded major flooding event for Longford was during 1823, with extensive flooding reported across the Northern Midlands region.<\/li>\n\n\n\n
    • The major flood event of 1863 was reported as a larger event than 1929 flood event.<\/li>\n\n\n\n
    • The 1929 flood is the highest Major flood level officially recorded with extensive flooding of Longford. This was an estimated 1% AEP flood event.<\/li>\n\n\n\n
    • The 1969 flood recorded extensive flooding and was before the modern levee structure. This was an estimated 3% AEP flood event.<\/li>\n\n\n\n
    • During the 2011 and 2016 flood events the Northern Midlands Council closed some levees as a precaution.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
