At least 50 fire alarms in the Hobart area were activated by the rain on the 4th and electrical faults caused power cuts to nearly 500 customers on the east coast. Communications networks were affected by the rain, causing some disruptions to over 1200 telephone services in the south, southeast and lower east.
More heavy rain and flooding in the east on the 25th and 26th.
On the 25th and 26th more heavy rain fell in eastern Tasmania as an easterly trough moved over the state and a weak low pressure system persisted near the east coast. During this time 171 mm fell at Nugent (including 137 mm in the 24 hours to 9 am on the 26th, which is its wettest day on record) and totals of 50 to 80 mm were widespread in the east and southeast. Many sites in the southeast had their wettest June day on record.
Rain on the 25th caused a landslip at St Marys, flash flooding and a string of car accidents in the southeast. Power was cut to around 2400 customers on the Forestier and Tasman Peninsulas and in the southern Midlands in the late afternoon and evening. The rain also caused rapid river rises, and on the 26th there was moderate flooding of the Macquarie River at Mt Morriston (peaking at 2.0 m at 11 pm), and minor flooding in the St Pauls River. There were also reports of flooding of the Clyde River north of Bothwell. By the 27th, minor flooding had also developed in the middle and lower reaches of the Macquarie River and in the Jordon River at Mauriceton, and on the 28th there was minor flooding of the upper reaches of the South Esk River. Strong flows from both the Macquarie and South Esk rivers caused water levels throughout the lower reaches of the Meander River to exceed the minor flood level to as far as the junction with the Liffey River. Many of these floods persisted into the first week of July.
|2009||July||Flooding on the 1st to
There was minor flooding in the North Esk, South Esk and Macquarie rivers between the 1st and 3rd after more rain fell into catchments already saturated from last month. This flooding was a continuation from flooding at the end of July.
Heavy rain and flooding from the 12th to the 15th
On the 11th and 12th heavy rain fell in northern areas as an active cold front crossed the state and a slow moving, complex low pressure system passed near the west coast. Several sites in the northwest recorded close to or over 100 mm in the 24 hours to 9 am on the 12th, with a further 10 to 20 mm falling in the next 24 hours. The rain caused moderate flooding of the Mersey and Meander rivers on the 12th and minor flooding of the North Esk and St Patricks rivers on the 12th and 13th. Minor flooding persisted in the lower reaches of the Meander River until the 15th. There was also minor flooding in the lower reaches of the Macquarie River from the 12th to 14th after strong inflows from the Lake and Isis rivers caused sharp rises in the Westmoor-Cressy area, and in the South Esk River on the 13th.
The flooding caused at least 20 road closures in the north and northwest. A Wildlife Park at Gunns Plains was forced to close for two days after flood damage, and there was minor flooding at the Deloraine Caravan Park.
|2009||August||Heavy rainfall and
flooding from the 12th to the 17th
In the period up to Wednesday 12th August, the synoptic situation had the development of a strong and persistent area of high pressure well to the south of Tasmania, with a broad area of low pressure moving eastwards from Victoria to lie south of Gabo Island by the evening of Tuesday 11th. Over the next few days the low pressure system passed close to Flinders Island before moving slowly southeast and weakening.
The low pressure system brought extensive rain mostly to the northeast of the state, but totals were heavy about the elevated areas of the East Coast. Three day totals ranged from 109 mm at Beauty Flat Rd to 231 mm at Valley Rd (Fingal), with the heaviest rainfall occurring on the Wednesday, 12th .
This rain caused major flooding in the middle reaches of the South Esk River at Llewellyn,peaking at 8.8 m 0n Thursday, 13th. Very high levels of moderate flooding occurred throughout the upper and lower reaches of both the South Esk and Macquarie rivers. The flood event is the most significant in the South Esk River since January 2004 and since May 1986 in the Macquarie River.
An additional 30 to 40 mm in the 24 hours to 9 am on Sunday 16th about the northeast highlands did cause a renewal of the flooding in the South Esk River, with low levels of moderate flooding in upper reaches. Some minor flooding also occurred about the lower reaches of the North Esk River.
Many local roads and bridges were cut by the flood waters. Some sandbagging of homes in Campbell Town adjacent to the Elizabeth River was undertaken by the SES during the Wednesday and Thursday when Lake Leake topped its spillway, perhaps for the first time since 1995 or 1996. This is significant since the lake was some 3 to 4 m below FSL prior to winter. No evacuations or stock losses have been reported; however, it is understood many crops and fences have been destroyed or damaged.
Persistent rainfall and more flooding from 19th to 31st
During the period from the 19th to 31st a stationary and deep low pressure system well to the southwest of the state brought a series of active cold fronts extending from the west and across the state about every 24 hours.
The complex synoptic situation resulted in episodes of moderate to locally heavy rainfall, mostly about the west and across the north of the state. While rainfalls were not excessive on the passage of each front, the cumulative totals were significant. In the 14-day period to 9 am on Monday 31st August, the West Coast, Central Plateau, Northern and Derwent Valley districts recorded the highest rainfall totals, averaging 241, 182 and 142 and 103 mm, respectively. Most other rainfall districts averaged between 50 and 65 mm of rainfall. The highest recorded rainfalls for the period occurred at Lake St. Clair (300 mm) and Lake Margaret (312 mm).
With many of the states� river catchments well saturated from previous rainfall throughout June, July and early August, and minor flooding continuing from the previous event in the lower reaches of the South Esk and Macquarie Rivers, the persistent rain was always going to cause a significant amount of flooding across the state.
Most other rivers in the north of the state began to rise on Thursday 20th, and by Friday 21st minor flooding had occurred about the upper reaches of the Meander River and about the lower reaches of the North Esk River. River levels also began to rise about the upper reaches of the South Esk River.
By Saturday 22nd, low levels of minor flooding had also developed in the middle and lower reaches of the Mersey River. In the Meander River minor flooding had extended into the middle reaches about the Deloraine Township, but much of the flooding in the Meander River occurred about the lower reaches. By midnight Strathbridge had peaked at 5.7 m, where the river remained for several days. In the south, the River Derwent also began to rise throughout much of the basin.
By Monday 24th, the Mersey River had exceeded the minor flood level in the lower reaches. The North Esk River also exceeded the minor flood level and by 8 pm had peaked at 3.1 m. River levels in the middle and lower reaches of the Huon River also began to rise. Strong inflows from the Ouse and Clyde rivers and the spilling of flows from Hydro Tasmania�s storages began to contribute to rises in the lower reaches of the River Derwent.
On Tuesday 25th, minor flooding had occurred in the lower Jordan River. Moderate flooding was developing in the upper reaches of the South Esk River, and by 7 am Fingal had peaked at 5.2 m. Minor flooding extended into the middle reaches of the South Esk River on Wednesday 26th.
Further rainfall about the north and west overnight Thursday 27th caused a further escalation of flooding around the state on Friday 28th. The lower reaches of the River Derwent below Meadowbank Dam peaked briefly at the major flood level of 7.1 m around 5 am, with moderate flooding extending downstream later in the morning. Further warnings of minor flooding were issued for the Forth and Huon rivers, but both systems peaked just below their respective minor flood levels. Renewed minor flooding also occurred about the lower reaches of the Mersey River.
By Sunday 30th, renewed minor flood peaks had occurred in the lower reaches of the Meander (Saturday 29th) and the North Esk rivers. Most river systems remained in minor flood to the end of the month.
Many local roads and bridges were cut by the flood waters. In the north, the Westmoor Bridge remained underwater for much of the period, and in the south, the Styx and Bushy Park bridges were also submerged. Many landslips were reported about the north of the state. The TFGA were also reported that poppy and woolgrowers could stand to loose financially as the wet conditions prevented growers sowing crops or the shearing of sheep. The Glenora District High School was closed on Friday 28th due to the flooding of roads and bridges in the Derwent Valley. Flooding also occurred about the low lying areas of New Norfolk, in particular the bowling greens and swimming pool.

Tasmania Flood Summary for years 2010 - Onwards
|2010||May||Heavy rain and flash
flooding in the northeast on the 28-29th
On the 28th severe flooding developed in and around St Marys after intense rainfall and thunderstorms in the afternoon. The rain was caused by the combination of a high to the southeast and developing low over South Australia that directed very moist and unstable air onto the northeast highlands; a "classic" situation for heavy rainfall in that area. A line of thunderstorms became stationary over the St Marys/St Patricks Head area during the afternoon and brought extremely heavy rain between 3 pm and 5 pm, including 109 mm at Gray.
By 9 am on the 29th Gray (Blueberry Cottage) had recorded 202.6 mm, Gray (Dalmayne Rd) 191.6 mm, St Marys (Clive Street) 158.4 mm and St Marys (Cullenswood) 143.8 mm. These are amongst the highest daily rainfall totals ever recorded in Tasmania during May.
The rain caused flooding of streams and rivers, along with damage to roads and other structures. There were reports of runoff a metre deep raging through the main street of St Mary. One car with four occupants was swept away in flood waters, and only avoided drowning when quick thinking locals used a bulldozer to reach the stranded vehicle. St Mary's Pass and Elephant Pass were closed to traffic due to rock slides and the dangerous road conditions, and residents of St Helens and St Marys were stranded without electricity. Several homes and businesses were flooded and extensively damaged. Anecdotal evidence from a local farmer suggests this storm has been the heaviest in his experience since the Portland-Fingal flash flooding event of 1974.
The intense rainfall, and further moderate to locally heavy rainfall about the upper South Esk catchment the following day caused moderate flooding throughout the Break O'Day, St Pauls and the middle reaches of the South Esk Rivers between Fingal and Avoca, with the rivers peaking over the 29th and 30th.
|2010||June||Heavy rain and flooding
in the northeast 17th to 20th
A cold front, with strong to gale force northerlies, including thunderstorms, brought extensive rain across the north of the state during the 17th, particularly about elevated areas of the northeast. Much of this rain fell overnight on the 16th, with 60-80 mm of rain reported in the 24 hours to 9 am on 17th.
Very significant river rises were observed in the upper reaches of the South Esk River, with moderate levels of flooding about the township of Fingal during the 18th.
Strong rises were also reported in the North Esk River during the 17th. A further 40 to 50 mm of rain in the Central North overnight on the 18th did cause minor flooding in the lower reaches of the North Esk River during the 19th and the 20th.
This further rainfall in the Central North caused strong flows in the Nile River, leading to flood concerns for the lower reaches of the South Esk River, particularly about the township of Perth, but river levels peaked below minor flood levels during the 21st.
|2010||July||Minor flooding North and
South Esk rivers on 11th and 12th
Moderate to locally heavy rainfall across the northeast highlands caused strong rises in both the North and South Esk rivers during the early hours of the morning, Sunday 11th. In the 24 hours to 9 am 25 to 55 mm of rain was reported, with the highest falls mainly about Mt Barrow and Upper Esk.
In the North Esk, the river peaked just above the minor flood level at Corra Linn about 5 pm on Sunday evening, whereas in the South Esk river levels throughout the upper reaches fall just short of the minor flood levels by late morning on the 12th.
Minor flooding Upper South Esk River 14th and 15th
To be comleted
|2010||August||Heavy rain and flooding
across eastern districts 11th to 15th
Heavy rain fell across eastern and central areas of Tasmania on the evening of the 10th and during the 11th as a slow-moving low pressure system, sandwiched between two intense highs, moved southeastwards through Victoria and Bass Strait, passing near Flinders Island. It was one of the wettest August days on record in Tasmania with over 100 mm falling through much of the east, and many sites having their highest August daily rainfall total on record. The highest totals of 199.4 mm Mount Wellington, 182.0 mm at Gray (Blueberry Cottage) and 175.2 mm at Gray (Dalmayne Road) were the 2nd, 3rd and 5th highest on record for anywhere in Tasmania during August. The rainband extended all the way down through the eastern states of Australia and had a tropical origin.
The heavy rain caused flash flooding and landslides that closed roads and cut off towns. Roads were closed in or near St Helens, Binalong Bay, Pyengana, Fingal, St Marys, Ansons Bay, Cranbrook and Claremont (in Hobart), amongst others. Several were still not open on the morning of the 12th. There were also a number of car crashes and two pedestrians in Hobart were hit while running across the road.
River flooding was widespread across the northeast and Midlands, with moderate to major flooding in the South Esk and Macquarie river basins and minor flooding in the North Esk river basin. Minor flooding affected the North Esk River between the 11th and 13th, peaking at 3.1 metres at Corra Linn early on the 12th. Also on the 11th, moderate flooding developed in the Break O?Day and St Pauls rivers, the middle and upper reaches South Esk river and the upper reaches of the Macquarie River. A major flood affected Llewellyn early on the 12th after the main flows of the South Esk and St Pauls rivers joined overnight, reaching a peak height of 8.5 metres. On the Macquarie River at Mount Morriston, the peak height of 2.6 metres was attained on the evening of the 11th. These floods gradually subsided over the following few days, but the flood waters moved downstream, resulting in minor to moderate flooding in the lower reaches from the 12th. On the South Esk River, Perth peaked at 7.5 metres early on the 13th, Longford peaked at 4.3 metres in the afternoon of the same day and Trevallyn Pond reached 128.9 metres overnight. Minor flooding continued until the 15th. Meanwhile, on the Macquarie River flooding affected the approaches to the Ross bridge on the 12th, with a peak height of 2.6 metres around 3 pm. In the lower reaches, Westmoor Bridge peaked at 4.3 metres late on the 13th, and Cressy peaked at 4.4 metres early on the 14th, then minor flooding persisted until the 18th.
Elsewhere, flooding of the Scamander River washed pipes from a
water treatment plant that was under construction out to sea, a
problem with muddy drinking water in Campbell Town was worsened
by flooding of the Elizabeth River, and the Hobart Rivulet went
within one metre of flooding. The rain also caused faulty
telephone lines at more than 300 homes and businesses from Coles
Bay to Eaglehawk Neck and across to Bronte Park in the Central
Floods in Huon River on 21st
Minor flooding developed in the Huon River on the 21st after falls of around 60 mm in the middle areas of the basin overnight as a low pressure system moved near the south coast of Tasmania. The river swelled during the morning, with the river height peaking at Harrisons Opening around midday (5 metres), Tahune Bridge in the early afternoon (4.1 metres), Judbury around 4 pm (3.5 metres) and Huonville around 5 pm (2.6 metres, just below the minor flood level of 3 metres). No consequences were reported.
|2010||September||Heavy rainfall and
flooding across northern Tasmania on 4th
On the 4th heavy rain fell across most of Tasmania as a deepening low pressure system approached from the northwest then crossed the state overnight. By 9 am, 15 to 25 mm had fallen in the northwest with light falls elsewhere. The rain continued during the day, with a further 81 mm at Mount Victoria, 75 mm at Mount Barrow and 63 mm at Mount Read during the next 24 hours. The event brought over 50 mm to most of the north, west and far south, with near 100 mm on higher ground in the northeast. The lightest falls were in the Midlands where a few sites had less than 10 mm.
The rain caused widespread flooding across the north, with minor flood levels exceeded in the Mersey, North Esk, St Patricks, South Esk, Macquarie and Meander rivers from late on the 4th or early on the 5th, and persisting until the 7th in some areas. Additionally, some flash flooding was reported across much of the north. Water affected several roads, but there were no reports of road closures.
Three rafters on the Mersey River discovered the perils of a flooded river on the 5th. Their raft overturned in fast flowing rapids about 15 km downstream of Mole Creek, and so had to spend a ?freezing? night in the bush before being rescued the next day.
|2010||December||Heavy rain and flooding
in the north 7th to 11th
Heavy rain fell across northern Tasmania on the 7th and 8th as a trough crossed the state. In two days, over 50 mm fell in northern areas between Wynyard and Devonport, and inland around Deloraine and Meander. Erriba had the highest 2-day total of 129 mm, and a handful of sites in the surrounding area received over 100 mm. The rain caused flooding of the Meander, Mersey, Forth and lower reaches of the Macquarie River.
Minor flooding developed in the Meander River basin on the 8th, moving into the middle reaches on the 9th and lower reaches on the 10th and 11th. Moderate flood levels were attained in the middle reaches, with a peak height of 2.8 metres at Deloraine early on the 9th. The caravan park at Deloraine was evacuated, and some roads were closed. Other peak heights were 2.7 metres at Meander late on the 8th and 6.3 metres at Strathbridge on the afternoon of the 9th.
In the Mersey River, moderate flooding developed in the middle reaches by the 9th, peaking at 3.6 metres at Kimberley early in the day. High levels of minor flooding affected the lower reaches, with Shale Road peaking at 5.4 metres. There was some flood damage at Bells Parade. On the 9th, a car with three passengers was washed 30 metres down the Mersey River after the driver attempted to drive through flood waters on Bridle Track Road near Kimberley.
There was also minor flooding in the lower reaches of the Forth (8 & 9th) and Macquarie (8 & 11th) Rivers. The Forth River peaked at 3.6 metres at Below Wilmot around midnight on the 8th. Strong rises in the upper and middle reaches were absorbed by the Paloona Dam. In the Macquarie River, strong inflows from the Lake River caused levels about Cressy to rise sharply overnight on the 8 & 9th. Cressy Pumps reached a peak of 3.4 metres in the morning on the 10th.
|2011||January||Heavy rain and Major
flooding across north 12th to 17th
A trough of low pressure brought very moist air across Tasmania and produced exceptionally heavy rainfall in the north between the 12th and 14th. A new state record January daily rainfall of 282 mm was set at Falmouth on the northern East Coast, and several other sites in the north and northeast had their wettest January day on record. The areas recording exceptionally high rainfall were relatively small, and have had higher totals in other months in the past, but it was somewhat unusual for such heavy falls to occur during summer.
On the northern East Coast, exceptionally heavy rain fell from the evening of the 12th until the afternoon of the 13th. Falmouth registered 282 mm in the 24 hours to 9 am on the 13th, giving it the wettest January day ever recorded at an official rain gauge in Tasmania. Scamander, with 278 mm, and St Helens (Kellraine), with 250 mm, also broke the old state record of 247 mm set at The Springs on Mount Wellington in 1916.
Scamander recorded a further 71 mm in the 24 hours to 9 am on the 14th and Falmouth a further 74 mm, giving 2-day totals in excess of 350 mm. There were unofficial (but credible) observations of nearly 400 mm in the area in the two days.
The largest totals appear to have been confined to a narrow strip extending from north of St Helens to south of Ironhouse Point. St Helens Aerodrome (near Stieglitz, southeast of the township) had less than half the rain reported just a few kilometres further inland. Heavy falls were also reported in the highlands (Gray received 215 mm for the 13th). Another area of heavy rain affected Tasmania?s North West Coast, with Yolla, inland from Burnie, receiving 100 mm in the 24 hours to 9 am on the 13th and a further 131 mm in the 24 hours to 9 am on the 14th. Both these values exceed the site?s previous January record of 70 mm in a day set in 1946. Together these gave Yolla its wettest January on record, and its second-wettest two-day period. Rain has been measured at Yolla since late 1905. Burnie (87 mm) and Wynyard Airport (107 mm) also had their wettest January days on the 13th, both by a considerable margin.
Further heavy falls occurred in the northern highlands during the 14th, mostly in the northwest in the morning and the northeast in the afternoon. Over 50 mm was reported in the 24 hours to 9 am on the 15th from several sites.
The heavy rain caused major flash flooding and river flooding. Major flooding occurred in the Mersey and Meander Rivers, with moderate flooding in the Forth, South Esk and lower reaches of the Macquarie River, and minor flooding in the North Esk River. Flooding persisted in the South Esk river basin until the 18th.
Impacts of the flooding were severe, with evacuations of over 100 homes and businesses. The most badly affected areas included St Helens, Scamander, Railton, Riana, Penguin, Wynyard, Forth, Gunns Plains and Cooee. Roads, rail lines and bridges were washed away, isolating some families in the northwest for weeks. St Helens was cut off, and several sections of the Tasman Highway were destroyed. Tourist attractions such as the Gunns Plains caves and Wings Wildlife Park were inundated with water and closed for weeks. On the 14th, over 50 Railton homes and businesses were damaged by flooding as several feet of water flowed through the main street. The beaches in Devonport were closed for about a week, due to elevated bacteria, and there were dramatic changes in rivers. Farmers were also severely affected, with several losing around half their crop. Overall, damage was estimated at $20 million statewide.
|2011||February||Minor flooding about
Upper South Esk 19th and 21st
This low crossing Tasmania on the 19th brought strong winds and the heavy rain to the north of the state. Minor flooding developed in the upper reaches of the South Esk River basin on the 20th.
rainfall and Major flooding in South Esk 22nd to 27th
Exceptionally heavy rainfall occurred in northeast Tasmania on the 23rd and 24th as a complex area of low pressure moved near the state. Gray (Dalmayne Road) recorded 327.2 mm in 24 hours, making it Tasmania?s third-highest daily rainfall total on record. The two-day totals were also extreme, with Gray?s total of 452.4 mm having only been exceeded once before, on 4?5 April 1929. The rain caused major flooding in the South Esk river basin, with peak heights in some places comparable to the floods of May 1969 and just slightly lower than the levels observed during the devastating floods of April 1929. There was also flash flooding and minor to moderate flooding in a number of other rivers in the northeast and central north.
Although the heaviest rain fell on the 23rd and 24th, heavy falls began in the northeast late on the 20th. A line of heavy showers affected a narrow area extending from about Pyengana in the north to Swansea in the south from very late on the 20th to the early hours of the 21st. Moonameeta recorded 80.6 mm, most of which fell in the two hours around midnight. Around the same time, Fingal received 63.8 mm and sites around Swansea had over 50 mm. The heavy falls were confined to a very narrow band ? sites just 20 km to the west and east reported less than 10 mm.
Showers developed in the northwest on the afternoon of the 21st, increasing to rain on the morning of the 22nd with locally heavy falls around the far northwest tip and on King Island. Three Hummock Island recorded 112.4 mm in the 24 hours to 9 am on the 23rd, and over 50 mm fell over much of King Island and at some inland areas of the northwest. Cape Grim, with 50.4 mm, had its wettest March day on record. This rain moved away to the west by noon on the 23rd.
The heaviest rain began in the northeast on the morning of the 23rd, with much of the area receiving over 50 mm in the 24 hours to 9 am on the 23rd. Pyengana had 138.0 mm and Gray had 125.2 mm. The rain eased for a few hours before increasing again during the late afternoon, and persisted until the morning of the 24th. This was when the highest totals were recorded, including 327.2 mm at Gray in the 24 hours to 9 am on the 24th. Most of the northeast had over 100 mm and at least 50 mm fell across the northeast third of the state. Nearly every site in the northeast there had either its wettest or near wettest March on record, and some sites had over five times their usual rainfall for March. A number of sites had their wettest March day on record.
The extremely heavy rainfall caused major flooding of the South Esk river basin, with peak heights attained in the upper reaches during the 24th and affecting the lower reaches on the 25th and 26th. Peak heights in the upper and middle reaches were comparable to the major floods of May 1969 and just slightly below those of April 1929.
The peak at Fingal was a major flood of 7.82 metres, the third-highest river level on record behind the floods of 1929 (9.52 metres) and 1969 (8.59 metres). Downstream at Llewellyn the river also reached the major flood level, peaking at 11.02 metres and exceeding the May 1969 record of 10.82 metres (readings at Llewellyn began around 1953). The flooding caused significant damage to bridges and roads, and many roads were closed and some towns cut off temporarily.
Further downstream at Longford, a major stage flood was observed with a peak of 6.40 metres, the third highest level on record but well short of the events in 1929 (9.33 metres) and 1969 (7.95 metres). Moderate flood levels were observed at Trevallyn Pond, upstream of Launceston. Levees in Launceston and Longford were not breached, but the Cataract Gorge flooded with damage to trees and footpaths, and a slalom course at Lake Trevallyn was washed away.
Moderate flooding also occurred throughout the lower reaches of the Macquarie River, with river levels remaining high throughout the weekend of 26th and 27th March and into the following week. There was also moderate flooding in the Ringarooma River, and minor flooding in the North Esk River. The George, Scamander, Douglas, and Wye rivers on the East Coast overflowed their banks.
|2011||April||Heavy rain along East
Coast 12th to 16th
During the period between the 10th and 14th April, a complex trough and low pressure system moved slowly across the state brought heavy rainfall to much of the eastern half of the Tasmania. Heavy rain commenced in the far northeast during Sunday 10th, and over the next few days progressively extended south along the East Coast and into the south of the state as the complex trough moved east and south away from the state.
In the 24 hours to 9 am on Monday 11th, Eddystone Point and Gladstone reported 153 mm and 145 mm of rain, respectively. Eddystone recorded a further 74 mm on the subsequent 24 hour period. During Monday and Tuesday, much of the heaviest rain was concentrated about the East Coast and northeast highlands. St Helens reported over 100 mm in the 24 hrs to 9am Wednesday 13th. During Tuesday evening and into Wednesday, rain extended into the southeast, with many stations reporting falls in excess of 75 mm for the 24 hour period ending 9 am Wednesday 13th.
While strong river rises occurred throughout the eastern half of the state, including flash flooding along the East Coast, moderate flooding also occurred in the upper and middle reaches of the South Esk basin, and minor flooding throughout the Macquarie basin.
Rivers commenced rising in the Break O'Day and Upper South Esk catchments by evening of Monday 11th,
Average catchment rainfall for event ranged between 96 mm in the St Pauls to 106 mm in the Break O'Day. Rainfall totals were less than half further west.
|2011||June||Heavy rain and flooding
throughout eastern half of state 8th to 12th
Between the 3rd and 9th a series of cold fronts crossed Tasmania, culminating with a deep low pressure system passing very near the south of the state on the 7th then moving close to the east coast on the 8th and away over the Tasman Sea on the 9th.
The rain caused flash flooding, particularly around the Huon Valley, New Norfolk, Sorell and Kingston, and forced many road closures. Many rivers in the south and east experienced rapid rises that led to flooding between the 8th and 10th. Moderate flooding occurred in the lower reaches of the Macquarie river basin, while minor flooding affected the upper and middle reaches of the Macquarie river basin along with the Derwent, Clyde, Huon, Jordon, North Esk and South Esk river basins. Flooding persisted for several days in the lower reaches of some of these rivers. Tasmanian rail freight services were disrupted by flooding on the 9th.
|2011||June||Heavy rain and flooding
central north 21st to 23rd
Between the 19th and 21st a moist northwest airstream blew over Tasmania with fronts and troughs enhancing moisture. Rain fell across the state, with 24-hour totals reaching up to around 100 mm in elevated areas in the north. Breona on the northern edge of the Central Plateau recorded 148 mm in the 72 hours to 9 am on the 21st, though nearly all of this would have fallen during the final 24 hours. Liffey and Quamby Bluff reported near 80 mm to 9 am on the 21st.
The rain caused moderate flooding in North Esk River and the lower reaches of Macquarie River, along with minor flooding throughout many northern river basins including Mersey, Meander, middle reaches of Macquarie and South Esk river basins. There were several road closures in the north and northeast, and wet conditions may have contributed to some car crashes in the northwest.
|2011||July||Flooding in North Esk
and Huon rivers 4th to 11th
A trough of low pressure moved across the state on the 3rd, followed by a low pressure system that passed just south of Tasmania on the night of the 4th. Strong and gusty northwest winds became cold southwesterlies as the low passed by, with some wind damage reported on the 5th, including around Launceston and Electrona.
Rainfall totals in northern, western and central parts generally ranged from 30 to 90 mm for the 3-day period between the 3rd and the 5th. Frankford Road at Wesley Vale was flooded on the 3rd, with minor flooding of the lower North Esk River late on the 4th and into the 5th. A peak river height of 3.0 metres was observed at Corra Linn.
|2011||August||Heavy rain and flooding
in the northeast 7th to 10th
The northeast of Tasmania experienced heavy rain with major flooding twice in August. The first event, from the 7th to the 10th, saw a broad area of low pressure remain slow moving to the north of Tasmania, with a trough extending down over the northeast of the state. Rainfall totals for the four days exceeded 100 mm at several sites, resulting in major flooding of the South Esk and Macquarie.
Rivers (peaking at 9.13 m at Llewellyn) and moderate flooding of
the North Esk and St Pauls Rivers. Mount Victoria received 261 mm
over the four days, 141 mm of that in one day on the 9th. Flash
flooding incidents were reported in the Goshen/St Helens area.
Further heavy rain and flooding in the northeast 16th to 19th
The second event, from the 16th to the 19th, was the fifth significant flooding event of the year in the northeast. Four-day rainfall totals again exceeded 100 mm at several sites; Cornwall received 153 mm in one day on the 18th. The South Esk River reached major flood level (peaking at 9.75 m at Llewellyn), and the North Esk and Macquarie rivers reached moderate flood level. This event was exacerbated by already wet ground and a high water table following the first flooding event.
There were landslips and several roads were closed with both events, and hundreds of thousands of dollars worth of damage was made to infrastructure. Flooding also disrupted freight services (the North-South and Fingal railway lines were closed).
