Officials scramble to find solution for dangerous river at Franz Josef
By local democracy reporter Brendon McMahon:
Engineers are surveying the new channel cut by the Waiho (Waiau) River at Franz Josef Glacier, but there are no plans to try to re-train the river back to its normal course.
About 95% of the main flow of the river starting flowing north through the Tatare Stream after heavy rain on January 18 to 20.
The river began shifting towards the neighbouring Tatare in mid-2023, forcing the council to abandon plans for a series of bunds (embankments) along the lower Waiho, below the Franz Josef town sewerage ponds.
While there is now concern about the river being up against the northern bank in front of the sewerage ponds, the southern bank stopbanks on the usually vulnerable Waiho Flat side of the river, have been left high and dry.
West Coast Regional Council engineering staff are now surveying those stopbanks before carrying out interim maintenance, and is also awaiting the results of a new Lidar survey of the riverbed, which uses light to create 3-D images of a landscape, to understand the new direction of the river's main channel.
A South Westland resident claimed last week a large bulldozer was being moved towards Franz Josef, probably in an effort to change the course of the river.
Responding, council chief executive Daryl Lew said the council was simply "mobilising" its resources in the area as it weighed options to deal with the situation.
Chairperson Peter Haddock said the bulldozer seen last week was nothing to do with the regional council or any plans to divert the Waiho River.
Haddock said he was aware a private landowner at Waiho Flat had contracted a large bulldozer to undertake work to protect their land, but it had nothing to do with the council.
"To my knowledge the bulldozer is not being engaged by council," he said.
However, the council was getting organised for the medium term maintenance of the existing stopbanks on the south side "to hold the line" while the riverbed was dry.
It hoped to get the green light from Government funding agency Kanoa to use some of the reserved $8.77 million granted under the original co-funded $24m Waiho protection scheme for that work, he said.
The south bank repairs were ahead of the longer term plan to abandon the Waiho Flat to the river by pulling down the banks, starting in about 10 years' time.
Haddock said options for possibly diverting the river channel would need to go to the community first before any decisions were made.
"Unless there's a distinct emergency, that needs to go to the rating district first."
The risk to the sewerage ponds on the north bank remained a matter for the Westland District Council to assess, he said.
While Westland had now said it wanted to add protection below the sewerage ponds, that would only be an interim solution and would also need to go to the rating district, "if it's deemed the ponds are at risk".
"The rating district has to decide if it has an appetite."
Haddock said the regional council continued to monitor the Waiho flowing via the Tatare Stream and the gorge.
If it continued to escalate, then any protection solutions from below the end of the sewerage ponds were likely to be beyond the rating district and council's capacity and would require Government intervention, he said.

Paddy Gower seeks ‘bloody great Cantab’
The Kiwi journalist drilling deep into the country’s biggest issues is on a mission to find the local greats.
Paddy Gower is looking for the Good Kiwi in every region to feature in his show, The F@#$ing News - Paddy Gower Live on Tour.
To nominate a Good Kiwi, email reporters@press.co.nz with the name and a description of why your nominee should win. You an also share the local issues you think Paddy needs to tackle in the comments below.
It could be the woman whose knitting circle has made 3800 items for victims of domestic violence, the guy running the length of Aotearoa for mental health, or the woman with terminal cancer who spends her time campaigning to raise awareness and save lives.
“Basically I am looking for ... a bloody great Cantab who just gets on and gets things done. The criteria is somebody who has a positive attitude and makes the community a better place," Gower said.
“I will give this person the 'Big Ups' they deserve, and the community can celebrate them with me.”
A Good Kiwi will feature in each of Gower’s live shows in 14 centres through November and December. He will name the Cantabrian Good Kiwi at his Christchurch show on the evening of Friday, November 22, at St Margaret’s College.
The F@#$ing News - Paddy Gower Live on Tour is a sort of book tour, sort of stand-up comedy, some journalistic yarns and memoir, and some motivational speaking - with a fair bit of local in each show.
Gower also wants to know about topics of interest in the region.
“I’m ... going to be taking on a big issue facing Canterbury and offering up solutions.”
A stinky suburb, a neighbourhood needing a round-about or a cathedral in disrepair - “I will make your views count”, he said.
“I'm touring the nation to spread positivity, optimism and good vibes.”
