Waiho River Future Management

‚ÄčFollowing the December 2010 region wide flooding, the West Coast Regional Council commissioned an independant river engineer, Bob Hall, to assess the river and write a follow up report to his Waiho River report written in 2000, which looked into the long term management of the Waiho River, at Franz Josef.

In preparing the report, input was sought from the Westland District Council, Department of Conservation and New Zealand Transport Authority staff, along with local people with experience in managing the river and regional council staff.

The report highlights the severe aggradation (gravel build up) that has occurred since the December 2010 floods, and the resulting change in the slope of the river fan which has caused the river to flow towards the Tatare River (especially during flood events). The report also covers potential threats to infrastructure and outlines options available to agencies that manage the infrastructure.

The mitigation options highlight key areas where the agencies need to work collaboratively to reduce the risks from the river.

WCRC Planning and Environment Manager Michael Meehan said the report certainly highlights how dynamic the Waiho River environment is. The report gives guidance on the major issues that we are all facing in managing the river. It shows how important it is that all agencies work together with the community to reduce the risks posed from the river.
