Newly Obtained Documents Reveal Private River Power Projects Killing Fish

Read this exclusive story from the Vancouver Sun on documents obtained by the Wilderness Committee that demonstrate private river power projects are killing fish. (Match 10, 2012)

The Mamquam River pours cold and fresh off the Coast Mountains, forming pools and canyons and chutes of white water on its way to the Squamish River and Howe Sound.

It was a natural place for federal fisheries biologists to assemble on an August 2010 weekend for swift-water safety training. Like the river itself, however, their exercise took an expected turn.

Rather than watch the Mamquam flow predictably to the sea, the biologists were dismayed to witness the water levels fluctuate wildly — and with dire consequences.

Young steelhead were dying, stranded without water.

The culprit? The Capital Power run-of-river hydro plant, located just upstream.

The independent power industry bills itself as green, sustainable and environmentally responsible.

But more than 3,000 pages of documents obtained separately by The Vancouver Sun and the Wilderness Committee through freedom of information requests show water-flow fluctuations caused by run-of-river hydro projects are killing fish — and the problem is not isolated.

While independent power producers insist their sector remains the cleanest energy option, the documents bolster environmentalists’ long-standing concerns about the industry.

“I’m seeing significant environmental problems,” said Gwen Barlee, policy director for the Wilderness Committee. “And that runs completely counter to what the companies are saying, which is essentially, ‘Trust us with your wild rivers and there won’t be any problems.’ ”

The documents detail repeated short-term fluctuations in water flows, resulting in the stranding and killing of juvenile fish downstream of two plants, Capital Power on the lower Mamquam and Innergex on Ashlu Creek, another tributary of the Squamish.
