Parts of New Norfolk are subject to flooding from the Derwent and\/or from the Lachlan Rivers.  The Derwent and Lachlan Rivers 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.<\/p>\n\n\n\n

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

Derwent River flooding<\/h2>\n\n\n\n

Widespread heavy rainfall in the Derwent catchment as far away as Lake St Clair and yingina\/ Great Lake can flood low-lying riverside areas of New Norfolk. The bridge across the river may be cut.  Such floods can isolate the New Norfolk and surrounding areas.<\/p>\n\n\n\n

Tides, melting snow, the level of soil moisture and the dam levels can impact flood levels.  During storms, sea levels can rise and this can increase flooding at high tide. However, dam level management is not likely to have a significant impact on flood levels during a major flood.<\/p>\n\n\n\n

Lachlan River flooding<\/h2>\n\n\n\n

Flooding from the Lachlan River is fed by high rainfall on kunanyi \/ Mount Wellington. It is difficult to predict and there is often little to no warning.  Tynwald Park and the nearby highway can become inundated.  See the related flood guide for the Lachlan River<\/a> \u66f4\u591a\u8be6\u60c5\u3002.<\/p>\n\n\n\n

New Norfolk has a long history of flooding.  The most significant flood since European settlement in 1960 flooded many homes and other buildings near the river 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.<\/p>\n\n\n\n

It is important to be prepared for major flooding events that may not have happened within most people\u2019s living memory.<\/p>\n\n\n\n
