N.W.T. diamond mine reports spill of 450 million litres of wastewater

The Diavik Diamond Mine in the Northwest Territories says 450 million litres of wastewater spilled due to a broken pipeline. The spill took place on Feb. 7 but wasn't reported to the Northwest Territories government until late last week. The territorial government says pipeline operators did not initially believe it needed to be reported as the wastewater leaked into a containment pond that was its final destination.

Rio Tinto completes Kemano hydropower project

Rio Tinto has commissioned a second tunnel to carry water into the Kemano Powerhouse in British Columbia, Canada, marking completion of the 960MW Kemano T2 hydropower project.

What killed these giant fish?

Nikolaus Gantner is searching for clues in 12 mysterious deaths along British Columbia’s Nechako River. It’s not your usual whodunnit.

Nechako First Nations call on Rio Tinto to release more water into the Nechako River

Nechako First Nations call on Rio Tinto to release more water into the Nechako River

A group of B.C. First Nations are calling on Australian mining giant Rio Tinto Alcan to release more water into the Nechako River after a sudden die-off of endangered white sturgeon. Last month, B.C.’s Ministry of Land, Water and Resource Stewardship reported 11 dead adult white sturgeon had been found in the Nechako River — an unusual occurrence. White sturgeon can grow to six metres long and live more than 100 years. They are an endangered species with between 300 and 600 remaining in the wild. Scientists said the fish had not died from disease, chemical exposure or due to fishing, and had no signs of injury. The government then reached out to local First Nations.

RDBN calls on Canada, B.C. and Rio Tinto to restore the natural flow of the Nechako River

RDBN calls on Canada, B.C. and Rio Tinto to restore the natural flow of the Nechako River

The Regional District of Bulkley-Nechako passed a resolution to acknowledge the “long-standing interference” on the claims of Indigenous communities in the Nechako First Nations region. Construction and operation of the Kenney Dam has caused interference on the claim of Aboriginal rights and title of First Nations, specifically Saik’uz First Nation, Stellat’en First Nation and Nadleh Whut’en, RDBN officials noted in a March 10 news release. Officials are asking the federal government, provincial government and Rio Tinto to do “all things necessary to support the efforts of the Nechako First Nations to restore the ecosystem functioning of the Nechako River and its affected tributaries.”
