CommentMr Wragge's forecast for four days from the 20th: "The tropical depression mentioned in the last forecast has made southing and developed great energy for the time of year. All districts from the Waikato are affected, but south therefrom high pressure rules and should later extend northward. This means boisterous weather, with very strong easterly to south-easterly rain squalls, occasioning local flooding of a minor nature. Conditions favourable for electric disturbances. Seas heavy, later moderating. Towards close of the period matters should improve, with high winds backing southerly as high pressure makes northing."

CauseA period of easterlies affected Otago, as a low moved southeastwards across the North Island. The centre of the storm passed in the north on the 22nd. It was followed by a "secondary", which apparently developed in the south.

FloodingFlooding
Comments:

CommentThe flood on the 22nd and 23rd was one of the most serious floods experienced in Dunedin. It was of a very extensive character and caused serious damage.

ImpactPortions of Caversham, South Dunedin, St. Kilda, the lower lying portions of the central and northern areas of the City and North East Valley were completely inundated.

DamageThe Water of Leith rose considerably and burst its banks in many places, causing extensive damage along its banks and flooding low-lying areas. Lindsay's Creek also overflowed.

Physical CharacteristicAt the Woodhaugh bridge the river was level with its banks. The water reached its highest at 4am on the 23rd.

Property DamageIn the Leith Valley, Davidson's sawmill suffered severe damage and little of the structure was left. The wreckage extended almost to Woodhaugh Gardens. The Woodhaugh Paper Mills were inundated and suffered slight damage. As the waters subsided, thick slime was left on the walls and roads.

Affected LifelineExtensive damage was done to Dunedin streets. The erosion of the banks of Water of Leith and Lindsay's Creek did considerable damage to the roadways skirting them. The Leith overflowed onto Duke Street late on the afternoon of the 22nd. Water flowed knee-deep down Malvern and Woodhaugh Streets. There was serious flooding in lower St. Andrew Street. There was swirling, fast-paced water on the North Road, originating from the hills behind Normanby. The water tore up road metal, leaving hollows the full length of the road and piles of metal. Huge pieces of asphalt were also lifted of footpaths and carried down the road. The main road footpath was broken away for 70 ft (20 m) of its length. The wires of the suspension bridge at the head of the Leith were banked up by debris, then the river overflowed, causing a rise of water at 4am on the 23rd. Leith Valley Road was closed, with a bridge destroyed by Nichol's Creek and timber piled up to 10 ft (3.0 m). Other highways closed included Kaikorai Valley Road, Union Street and Cliffs Road. The Main South road and the Green Island-Taieri Mouth road were scoured in many places. The Main South road was blocked at Green Island. At Forbury corner in Caversham, the water was surging down David Street from the Main South road.

Affected LifelineSeveral bridges were swept away in the Leith Valley. The Nicholl's Creek bridge near Leith Valley Scool was washed away. Union Street Bridge was closed on the morning of the 23rd after the approach collapsed. The approaches were seriously damaged by erosion. A small bridge at Green Island was swept away. The bridge at Tomahawk was washed away.

Physical CharacteristicThe Leith had a peak discharge of 3,000 cusecs (85 cumecs). The velocity of the river below Harbour Terrace was said to be over 3,000 cusecs.

Physical CharacteristicThe flood discharge was estimated at 7,000 cusecs (198 cumecs) (MacLean, McGregor Wilke, and Alexander).

Property DamageIn Ferguson's store the damage to goods amounted to £60-£100 ($5200-$8700 2008 dollars). Many outbuildings were washed away by the flood waters of the Leith.

Physical CharacteristicThe Leith bed widened to 30 ft (9.1 m) in places.

Affected LifelineExtensive damage was done to telegraph poles and wires.

Affected LifelineThe flood waters of Nichol's Creek broke the water main from the reservoir, leaving 12 Roslyn residents without water. The water main was also broken on Ross Creek.

DamageSouth Dunedin suffered the most severe damage.

Physical CharacteristicWater in South Dunedin streets was waist deep.

Affected LifelineNo express trains were running. At Burnside, a swollen stream poured through the railway tunnel through Old Caversham. Extensive damage was done to the track in the tunnel. In the early hours of the 23rd, the railway line at the Pelichet Bay (North Dunedin) station was submerged and the officer had to take refuge elsewhere. The Caversham railway bridge had a pool of water measuring 200 square yards (167 m^2) and over 5 ft (1.5 m) deep at its deepest.

Physical CharacteristicThere was 4 ft (1.2 m) of water in the Caversham tunnel.

Physical CharacteristicThe Pelichet Bay station officer waded through water up to his neck.

EvacueesLarge numbers of people in the North-East Valley and the north end of the town adjacent to the Leith were flooded out, and vacated their homes. Hundreds of people were driven from their homes. Residents of Harbour Terrace were evacuated. Almost all the residents on Grosvenor Street and Park Terrace in South Dunedin left their homes. At Tainui, almost all the residents left their houses on the afternoon of the 22nd. Hundreds of people had to be fed and accommodated by the Salvation Army due to their homes being damaged. Many of the householders nearest to the worst zones did not have time to prepare to evacuate their homes.

Physical CharacteristicThe Carisbrook Ground was like a vast lake, with water up to 3 ft (90 cm) deep.

ImpactQuite a number of houses in the back streets were invaded by the rising water. Tainui Flat was inundated. Portions of Musselburgh suffered badly and water from other parts of the Flat invaded many homes. The worst state of affairs appeared to be in the district south of King Edward Street, in St Kilda.

Affected LifelineTram services were disorganised and interrupted. Frequent derailments of the city tram due to silted lines and flooded streets made it impossible to carry on.

Duration:   6  days - From the 18th till the 23rd of April.

CommentMr Wragge's forecast for four days from the 20th: "The tropical depression mentioned in the last forecast has made southing and developed great energy for the time of year. All districts from the Waikato are affected, but south therefrom high pressure rules and should later extend northward. This means boisterous weather, with very strong easterly to south-easterly rain squalls, occasioning local flooding of a minor nature. Conditions favourable for electric disturbances. Seas heavy, later moderating. Towards close of the period matters should improve, with high winds backing southerly as high pressure makes northing."

CauseA period of easterlies affected Otago, as a low moved southeastwards across the North Island. The centre of the storm passed in the north on the 22nd. It was followed by a "secondary", which apparently developed in the south.

FloodingFlooding
Comments:

CommentThe flood on the 22nd and 23rd was one of the most serious floods experienced in Dunedin. It was of a very extensive character and caused serious damage.

ImpactPortions of Caversham, South Dunedin, St. Kilda, the lower lying portions of the central and northern areas of the City and North East Valley were completely inundated.

DamageThe Water of Leith rose considerably and burst its banks in many places, causing extensive damage along its banks and flooding low-lying areas. Lindsay's Creek also overflowed.

Physical CharacteristicAt the Woodhaugh bridge the river was level with its banks. The water reached its highest at 4am on the 23rd.

Property DamageIn the Leith Valley, Davidson's sawmill suffered severe damage and little of the structure was left. The wreckage extended almost to Woodhaugh Gardens. The Woodhaugh Paper Mills were inundated and suffered slight damage. As the waters subsided, thick slime was left on the walls and roads.

Affected LifelineExtensive damage was done to Dunedin streets. The erosion of the banks of Water of Leith and Lindsay's Creek did considerable damage to the roadways skirting them. The Leith overflowed onto Duke Street late on the afternoon of the 22nd. Water flowed knee-deep down Malvern and Woodhaugh Streets. There was serious flooding in lower St. Andrew Street. There was swirling, fast-paced water on the North Road, originating from the hills behind Normanby. The water tore up road metal, leaving hollows the full length of the road and piles of metal. Huge pieces of asphalt were also lifted of footpaths and carried down the road. The main road footpath was broken away for 70 ft (20 m) of its length. The wires of the suspension bridge at the head of the Leith were banked up by debris, then the river overflowed, causing a rise of water at 4am on the 23rd. Leith Valley Road was closed, with a bridge destroyed by Nichol's Creek and timber piled up to 10 ft (3.0 m). Other highways closed included Kaikorai Valley Road, Union Street and Cliffs Road. The Main South road and the Green Island-Taieri Mouth road were scoured in many places. The Main South road was blocked at Green Island. At Forbury corner in Caversham, the water was surging down David Street from the Main South road.

Affected LifelineSeveral bridges were swept away in the Leith Valley. The Nicholl's Creek bridge near Leith Valley Scool was washed away. Union Street Bridge was closed on the morning of the 23rd after the approach collapsed. The approaches were seriously damaged by erosion. A small bridge at Green Island was swept away. The bridge at Tomahawk was washed away.

Physical CharacteristicThe Leith had a peak discharge of 3,000 cusecs (85 cumecs). The velocity of the river below Harbour Terrace was said to be over 3,000 cusecs.

Physical CharacteristicThe flood discharge was estimated at 7,000 cusecs (198 cumecs) (MacLean, McGregor Wilke, and Alexander).

Property DamageIn Ferguson's store the damage to goods amounted to £60-£100 ($5200-$8700 2008 dollars). Many outbuildings were washed away by the flood waters of the Leith.

Physical CharacteristicThe Leith bed widened to 30 ft (9.1 m) in places.

Affected LifelineExtensive damage was done to telegraph poles and wires.

Affected LifelineThe flood waters of Nichol's Creek broke the water main from the reservoir, leaving 12 Roslyn residents without water. The water main was also broken on Ross Creek.

DamageSouth Dunedin suffered the most severe damage.

Physical CharacteristicWater in South Dunedin streets was waist deep.

Affected LifelineNo express trains were running. At Burnside, a swollen stream poured through the railway tunnel through Old Caversham. Extensive damage was done to the track in the tunnel. In the early hours of the 23rd, the railway line at the Pelichet Bay (North Dunedin) station was submerged and the officer had to take refuge elsewhere. The Caversham railway bridge had a pool of water measuring 200 square yards (167 m^2) and over 5 ft (1.5 m) deep at its deepest.

Physical CharacteristicThere was 4 ft (1.2 m) of water in the Caversham tunnel.

Physical CharacteristicThe Pelichet Bay station officer waded through water up to his neck.

EvacueesLarge numbers of people in the North-East Valley and the north end of the town adjacent to the Leith were flooded out, and vacated their homes. Hundreds of people were driven from their homes. Residents of Harbour Terrace were evacuated. Almost all the residents on Grosvenor Street and Park Terrace in South Dunedin left their homes. At Tainui, almost all the residents left their houses on the afternoon of the 22nd. Hundreds of people had to be fed and accommodated by the Salvation Army due to their homes being damaged. Many of the householders nearest to the worst zones did not have time to prepare to evacuate their homes.

Physical CharacteristicThe Carisbrook Ground was like a vast lake, with water up to 3 ft (90 cm) deep.

ImpactQuite a number of houses in the back streets were invaded by the rising water. Tainui Flat was inundated. Portions of Musselburgh suffered badly and water from other parts of the Flat invaded many homes. The worst state of affairs appeared to be in the district south of King Edward Street, in St Kilda.

Affected LifelineTram services were disorganised and interrupted. Frequent derailments of the city tram due to silted lines and flooded streets made it impossible to carry on.

Affected LifelineGas was in short supply due to the works being flooded. Manufacturing stopped at about 3pm on the 22nd and resumed about 12am on the 23rd.

Physical CharacteristicThere was up to 2 ft (60 cm) of water on the furnace floor of the gasworks.

Physical CharacteristicWater covered roads to a depth of as much as 3 ft (90 cm) in some places.

Physical CharacteristicThe water in many business places was several feet deep.

Property DamageExtensive damage was done to household goods because of the suddeness of the flooding and swift evacuation. Damage to furniture and effects was worth many hundreds of pounds. Extensive damage to was also done to goods in the cellars of business premises.

ImpactMany business premises and private residences were invaded. At least 40 houses around the Gardens were flooded, in many places 2 ft (60 cm) deep.

ImpactIn the Lake Logan (Logan Park) area there was a sheet of water. Most of the houses on Harbour Terrace were flooded, some to over 2 ft (60 cm). The Caledonian Ground at Logan Park was covered and several of the houses on the town side were threatened.

ImpactThere were geysers throughout much of the city from caps blown off drains, the worst being on Wilkie Road.

ImpactGreen Island suffered severely, with a large portion of the area under water.

Physical CharacteristicThree properties had up to 6 ft (1.8 m) of water inside and the water was up to the top of picket fences.

Affected LifelineSome of these houses were completely isolated.

Physical CharacteristicHouses in Harrow Street were surrounded by 4 ft (1.2 m) of water and some marooned people had to seek refuge in upper stories.

Stock DamageOne man's chicken houses and about 200 chickens were destroyed. Many chicken houses were washed away by the flood waters of the Leith.

Physical CharacteristicThe water level on Grosvenor Street, South Dunedin, was 4 ft (1.2 m) on the 23rd.

CommentThe water continued rising in South Dunedin, St. Kilda, Musselburgh and Tainui Water after the rain had stopped, as it was unable to get to the harbour through the stormwater channels.

Property DamageAt the Dental Scool, several galvanised buildings were completely washed away, with portions found down the harbour at Ravensbourne. Hundreds of pounds of stores were destroyed and water worked into foundations.

ImpactTwo families in a house at the bottom of Union Street, as well as others, were rescued by boat.
