Freeing salmon trapped at Fraser River slide site the focus of experts

The Chilliwack Progress –

Finding the best way to release the salmon trapped by a landslide in the Fraser River near Big Bar is under careful consideration by experts.

Fisheries and Oceans Canada and B.C. government officials announced Friday at a technical briefing that they are working together to address impacts of the June 23 slide at a remote and unstable part of the Fraser River. An “incident command post” was set up at Lillooet with several agencies working in tandem to find the best remediation options.

Options and remediation now being considered:

• Take no action and continue to monitor fish passage;

• Explore options to remove rock obstruction; or

• Physically move the trapped fish upstream.

“Each of these options come with potential benefits and some risk or possible risk of consequence. For this reason, we continue to thoroughly assess each option,” according to the update July 7.

What they believe happened was that a massive slab of rock sheared off and slid into a steep and narrow section of the river, creating a five-metre waterfall and a barrier to fish passage. Several types of fish are being impacted based on the “magnitude” of the obstruction, including some of conservation concern, officials said.
