A forum of groups opposed to hydro dams on the Clutha River is rallying support from throughout New Zealand, in preparation for a fight to save Otago's river landscape.
Members of the Clutha River Forum gathered in Alexandra last week to discuss how best to prevent "think big" dams on the Clutha, spokesman Lewis Verduyn said.
Representatives from the Upper Clutha River Guardians, Clutha Mata-Au River Parkway Group, Central Otago Environmental Society, Save Central, Beaumont Residents Group, Lower Clutha River Guardians, and the Dunedin branch of Forest and Bird attended.
Mr Verduyn said at present those groups formed the forum, but there was strong interest from other individuals, groups, and organisations throughout the country.
"There is a lot of support from other groups and people who want to be involved, but none of the others have been confirmed yet. We've been working on expanding our support base and have been networking with other groups throughout New Zealand in similar situations."
He said 20 rivers in the country were now threatened by dams.
About 60 people are associated with the forum's opposition to hydro dams.
Mr Verduyn said the forum, which comprises 15 people, initiated a research document on hydro dams when it met about two months ago, and had recently been analysing the finished product.
The 15-page document focused on New Zealand's demand for electricity, and whether additional generation was necessary.
"We have a lot of research behind what we are saying and doing.
"The forum has considered Contact Energy's four dam options and unanimously supports option five - no more dams," he said.
As well as research, the forum had other strategies and campaign ideas "in the pipeline".
