Flooding and slips after delugeBy PAUL GORMAN - The Press | 5:00AM - Monday, 18 May 2009IN FLOOD: Tim and Sandra Jorgensen, of
Darfield watch the Rakaia surge through the
Rakaia Gorge. — DAVID HALLETT/The Press.Raging rivers roared across the South Island yesterday, flooding Omarama, threatening bridges and blocking the main highway south.Rain fell on already sodden high-country catchments, while melting snow turned the Rangitata, Waitaki and Rakaia rivers into torrents.
The Rangitata River near State Highway 1 peaked about 2.30pm, with water bursting through its southern bank, flowing across farmland and roads, closing the highway and forcing motorists to detour inland through Geraldine.
The main trunk railway line was also closed between the Rangitata River and Temuka.
KiwiRail spokesman Kevin Ramshaw said workers would inspect the track, culverts and bridges today before deciding when to reopen the line.
The Waitaki River was expected to peak last night. As a precaution, the 113-year-old bridges between Kurow and Hakataramea were closed until 7am today. Floods in 1995 weakened some of the wooden piers on the northern bridge across the Waitaki.
The old Waimakariri River bridge near Kaiapoi was also closed for a time yesterday.
Omarama was on the brink of a Civil Defence emergency yesterday, with 31 people evacuated from the camping ground at 5.30am, along with three residents living near the river.
A major slip closed the Lindis Pass, while a slip on the Mt Cook Highway caused problems.
State Highway 77 was closed to campervans and other high-sided vehicles because of high winds.
MetService severe weather forecaster Ian Miller said the weather system had brought massive amounts of rain to the West Coast and the Southern Alps.
The country's wettest place Cropp River inland from Hokitika had 440 millimetres of rain between midnight Friday and midnight Saturday, with another 106mm from then until 7am yesterday.
More than 300mm had fallen close to Mount Cook village and parts of the Mackenzie Country had about 70mm.
Meridian Energy spokeswoman Claire Shaw said vast inflows to the Waitaki hydro system had forced the power company to spill water.
"We started spilling Friday night at Benmore to put a hole in the lake, so when the expected rain came down we had somewhere to put it. Spilling at Aviemore followed pretty soon after that, and we started spilling at Pukaki today."
It was difficult to know how long the spilling would continue, she said.
Environment Canterbury southern flood controller Graham Sullivan said the Waitaki was a massive river, but an expected peak flow of 1800 to 2000 cubic metres a second would cause problems and surface flooding.
"It could well be the biggest flow since 1995.
"It's been a combination of three things a lot of snow, a lot of rain, and we already had a saturated catchment from a fortnight or so ago, and those things have combined to provide an enormous amount of water."
Another burst of rain is expected in the high country and the Canterbury foothills this morning, but should clear this afternoon.
Last night, MetService forecaster Mark Pascoe warned the weather was about to turn cold, with south to south-westerly winds this week bringing a chance of snow to low levels in parts of the south on Wednesday.
Snow was possible to about 400 metres in Canterbury and to 200m to 300m further south.

Deluge brings chaos to regionLindis Pass closed after bridge scouredBy JEFF TOLLAN - The Timaru Herald | 5:00AM - Monday, 18 May 2009TOO CLOSE FOR COMFORT: Rising floodwaters near
Falstone Reserve at Lake Benmore put at least one
caravan in a precarious position yesterday.
— STEPHEN BROWN/The Timaru Herald.The surge of water down the Omarama Stream has forced the closure of the bridge on State Highway 8, completely shutting the Lindis Pass to heavy vehicles.New Zealand Transport Agency operations manager for Otago/Southland Murray Clarke said the high flows scoured an abutment of the bridge.
The damage was found about 9.30am today and crews are now at the scene trying to repair the structure.
Mr Clarke said light vehicles are taking a detour along a private road.
``It's quite a big job to get opened. Water got in behind the embankment where the road is up against the end of the bridge.''
Nobody can recall when the bridge was last closed due to scouring, Mr Clarke said.
It follows on from the king-hit to the region by the weekend's weather; which forced evacuations, blew part of the Opuha Dam out, isolated townships and put Omarama on the brink of a Civil Defence emergency.
And that was just the start.
The Waitaki River's Kurow bridges were last night closed from 6pm until 7am today due to high river levels.
State Highway One was closed from Orari to Ealing yesterday afternoon after the Rangitata River breached a stop bank. It was reopened early this morning.
Trains were also stopped, with the line between Temuka and Bankside at Rangitata closed due to safety concerns.
Kiwi Rail public affairs manager Kevin Ramshaw said workers will inspect the track, culverts and bridges this morning before deciding whether to reopen the line. So far two trains have been delayed.
Traffic also faced delays yesterday, with diversions through Geraldine from Hinds and Orari. Journeys were made even slower by the one-way bridge north of Geraldine.
By 5pm yesterday up to 200 vehicles were queuing either side of the bridge as contractors tried to keep traffic moving.
As night drew on, roads were still closed as water, up to knee height in places, ran across farmland and roads.
New Zealand Transport Agency regional manager Colin Hey said the highway between Orari and Ealing would remain closed through last night, and be reassessed this morning.
"It's really a matter of having a look in the morning, reviewing the situation and playing it by ear."
He said that, in parts, the water was thought to be about half a metre deep, but "nobody's game to drive through it" to measure the depth.
One contractor had tried but turned back when water started flowing over the bonnet of his vehicle.
Even when the water recedes, Mr Hey said the highway would most likely need repairs to the seal before it could open.
Omarama has also been plagued by water worries.
Early yesterday the town was "on the edge" of a Civil Defence emergency, with water ankle-deep in the main street and up to a metre deep in other places.
Constable Paul Mander of the Kurow police said the town "just got by" without declaring an emergency, though 31 people were evacuated from the camping ground at 5.30am, along with three residents living near the river.
He said emergency services, including Civil Defence, had been planning for the rain.
"We knew it was coming and semi-prepared for it last night [Saturday]."
A major slip in the Lindis Pass saw that road closed, while a slip on the Mt Cook Highway, just north of Peter's Lookout, partially closed one lane.
"It's quite unpredictable," Mr Mander said of the flooding and slips.
"A few bridge approaches have been damaged and we've still got quite a lot of rural residents who are isolated, but it's business as usual for them."
At Huxley Lodge, in the Hopkins Valley at the head of Lake Ohau, 17 school pupils and their teachers from John McGlashan College in Dunedin were trapped, the roads too dangerous to get in or out of the area.
However, Mr Mander said police have spoken to the group and are satisfied they will be OK.
"They were planning to stay in there for a week anyway, it's just the access [that is the problem]."
And when it wasn't raining, it was blowing.
State Highway 77 was closed to campervans and other high-sided vehicles because of high winds. There were reports yesterday that in exposed areas the winds were too strong for people to stand upright.

Roads closed, stock moved as deluge hitsBy WILL HINE in Queenstown - The Southland Times | 5:00AM - Monday, 18 May 2009Roads were closed and stock was shifted after a deluge of rain hit the Southern Lakes and Central Otago during the weekend.Queenstown and Wanaka received more than a month's rainfall in just three days, causing problems in the Lakes district and further downstream in Central.
The Clutha River rose sharply in several places, triggering flood alerts, while the Dart River near Glenorchy swelled from a sedate 50 cubic metres a second to more than 650 cumecs yesterday.
Lake Wakatipu rose 60cm and Lake Wanaka rose about a metre but neither threatened to flood.
The wet weather caused problems on roads, with at least one traffic incident caused by flooding.
Acting Sergeant Terry Wood, of Queenstown, said a motorist was taken to hospital with chest pain after his vehicle left Glenorchy Rd on Saturday afternoon.
"He was driving into Wilson's Bay, hit some water and aquaplaned across into a tree."
The man was later discharged from hospital, Mr Wood said.
There was also a slip about 22km from Queenstown on Glenorchy Rd, which blocked one lane, and flooding on Frankton Rd.
Constable Mike Johnston, of Wanaka, said the Hawea-Makarora road was blocked by slips twice on Saturday.
Further north, a gravel road surrounding a bridge in Matukituki Valley was washed away on Saturday night but was rebuilt by contractors yesterday.
Cromwell police closed State Highway 8 at Tarras because of slips on the Omarama side of the Lindis Pass, before reopening the route yesterday afternoon.
Otago Regional Council environmental information and science director John Threlfall said he was tracking river levels and had an eye on waterways near Balclutha.
"You've got Wakatipu, Wanaka and Hawea combining with the Manuherikia, which, all combined, is giving us the high flows in the south end. We're advising farmers to move stock from low-lying levels but we don't expect it to be too much of a problem."
Central Otago Mayor Malcolm Macpherson said the Manuherikia River was high. The Clutha River was high but it was not causing any problems for the Manuherikia flow to clear.
"We are not near any of our risk levels yet ... it will depend on just how much more rain we get in the high catchment areas," he said.
Coronet Peak ski area manager Hamish McCrostie said torrential rain washed away a lot of the snow that had fallen during the week.
"It's snowing again now, so that bodes well," he said. "One good thing is the rain's filled up all the reservoirs so we've got plenty of water for snow-making."

Cyclist survives torrentClyde coastguard comes to rescue as man strandedBy WILL HINE in Queenstown - The Southland Times | 5:00AM - Monday, 18 May 2009OFF TRACK: Richard Todd, of Alexandra, who
was rescued by the Clyde coastguard after
getting stranded on a bike track in Central
Otago at the weekend.
— BARBARA WITHINGTON/The Southland Times.An Alexandra man found himself up to his neck in a "raging torrent" yesterday after biking along a track next to the swollen Clutha River.The Clyde coastguard rescued Richard Todd after he was stranded biking along the rail trail from Clyde to Alexandra.
Before setting off Mr Todd had seen the Clyde Dam spilling water "like Niagara Falls" but he was familiar with the riverside track and decided to go ahead with his regular ride.
Mr Todd said he was cycling along the trail when he got to a pool of water about 30cm deep on the track. "That was all right but then I came to another lot. It was probably up to my handlebars."
Mr Todd's bike slipped off a submerged wooden section.
He managed to unhook his feet from his pedals but was starting to get nervous.
"I thought, `how far do I go'? I was getting too deep, I was up to my neck in it. It was getting deeper and deeper."
Mr Todd decided to turn back but by then the river was a foot higher and rising.
He found an outcrop of land, which had become an island of sorts, and called rescue services; the Clyde coastguard arrived within 20 minutes.
"I happened to have my mobile in a waterproof pouch in my backpack, luckily. Otherwise I think I would have been screwed. I was very cold and ... all I could see around me was water. Thank God for the search and rescue."
Recovering at his house after the ordeal, Mr Todd said he had been "quietly sh***ing himself" as the water rose around him.
He paid tribute to the excellent work of emergency services and said he planned to thank them in person.
Contact Energy spokesman Jonathan Hill said the Clyde Dam floodgates were opened during the weekend to let the Clutha River flow at its natural rate.
"The fact the dam is there is irrelevant because we're simply passing the volume of water upstream of the dam to downstream of the dam."
Mr Hill said the river was running at about 1500 cubic metres of water a second, three times its normal flow rate.

Snow on the waySome South Island roads reopenBy PAUL GORMAN - The Press | 12:51PM - Monday, 18 May 2009An early winter snowfall is brewing south of the country and is expected to bring snow to much of Canterbury from tomorrow night through to Thursday.Weather forecasters are warning of plunging temperatures and snow to low levels, possibly as low as sea-level, on Wednesday.
Blue Skies Weather forecaster Tony Trewinnard says south-westerly winds will become very cold tomorrow in the wake of a cold front, and even colder on Wednesday.
Rain will spread north tomorrow afternoon, with snow lowering to 200m in the evening, and flurries to sea-level on Wednesday, although little snow is expected to settle that low down.
From tomorrow night until Thursday morning 3 to 5cm could accumulate between 200m and 400m, with up to 10cm above that, Trewinnard said.
MetService severe weather forecaster Mark Pascoe said the icy blast would be worst in Southland and eastern Otago, leading to dangerous driving conditions on higher roads.
ROADS REOPENSouth Island roads closed during yesterday's flooding have reopened.
Water across State Highway 1 near Rangitata, which forced motorists to detour inland through Geraldine, has cleared.
In North Otago, the 113-year-old Waitaki River bridges between Kurow and Hakataramea reopened this morning.
Environment Canterbury southern flood controller Graham Sullivan said the crossing would remain open unless the river flow reached a trigger point of 1500 cubic metres of water a second.
Caution is being urged on State Highway 8 in the Lindis Pass, from Omarama to Tarras.

Storm, winds cause havocBy CLAIRE CONNELL - The Marlborough Express | 1:00PM - Monday, 18 May 2009High winds caused havoc in Marlborough at the weekend, uprooting trees, throwing a car-sized wooden shed 600 metres across a paddock, ripping roofs off houses, and leaving 6000 homes without power.Linkwater couple Barbara and Jarrett Jenkins woke to chaos outside their home at about 4.30am yesterday.
"This wind just came out of nowhere; there was this roar and a bang and the wind hit a macrocarpa tree just about hit the house," Mrs Jenkins said today.
The tree was uprooted and just missed the corner of the house.
She said their wood-and-iron calf shed, big enough to fit a car inside, was uplifted and thrown 600m to the other side of the paddock.
Their hayshed roof came off and was hurled into the creek.
Their conservatory suffered, too, with four sheets of heavy plastic bending back. The couple had to tie them down, but water was still coming in the roof this morning.
"We had a two-seater wooden swing thrown 50 feet [16 metres]. I mean, it was silly to go outside; there wasn't much we could do until daylight."
The couple have insurance.
Despite being one of the worst affected, their power remained on.
Steve Benjamin, resident of Waikakaho Valley, said power was out at his house from Saturday night until lunchtime yesterday. There was no damage to his house.
Linkwater Services service station co-owner John Smith said it was a "pretty rough night" at Linkwater, with reports of three residents having roofs blown off their sheds. Power was out in the area from 3am to 7am on Sunday, but was restored quickly thanks to the efforts of Marlborough Lines staff, he said.
Marlborough Lines engineer Richard Steer said about 6000 customers were affected at some stage with trees falling on lines. Power was out ranging from a few minutes to 14 hours at Waikakaho Valley.
Areas disrupted included Onamalutu, Wairau Valley township, Spring Creek, Ngakuta (near Linkwater), Springlands, Linkwater, and areas in the Marlborough Sounds.
Waikakaho Valley, north of the Wairau River, and Wakamarina (near Canvastown) were also affected, with 10 trees down.
Mr Steer said Marlborough Lines had about 30 staff working, and finished about 9pm last night. All power had been restored apart from a few isolated houses, he said.
Marlborough Roads asset manager David Miller reported multiple trees down in areas north of Blenheim. Beech trees were down on State Highway 1 behind Renwick, State Highway 63, State Highway 6 west of Havelock, and the Marlborough Sounds behind Kenepuru Heads.
Ellen Plasier, who lives in the Outer Pelorus Sound with her family, said they had no reports of major damage but many branches came down on Saturday night.
