More solutions are being found to get thousands of salmon past a landslide in the Fraser River, provincial and federal officials said this week, adding they’re starting to see positive results.
An update posted by Fisheries and Oceans Canada (DFO) and the B.C. government Saturday said crews are making “encouraging progress” in building a natural fish passage on the river’s edge after blasting more rock on Thursday.

The rocks came down in late June in a section of the river north of Big Bar, creating a five-metre waterfall that has blocked the salmon from swimming upstream to spawn.
The blast created enough material to move boulders in place to create the salmon passage. Another controlled blast was expected to take place Sunday to create more material.
As of Sunday, officials say roughly 4,000 sockeye and chinook salmon have been transported upstream by crews. No fish have been able to make it through the rapids on their own as of yet.

A variety of methods are being used to transport the salmon past the slide, including using helicopters carrying oxygenated tanks filled in nearby staging ponds.
A fish ladder and fish wheel have also been deployed, the latter of which was successfully tested Friday.

The fish wheel was brought in by the Kitsumkalum Band, one of several local First Nations assisting the province and the DFO with the operation.
An update posted Friday said the fish wheel would be fully operational by Saturday, but officials have since pushed that date to “the near future.”
Crews are continuing to work on scaling the rock above the slide to prevent future incidents.
There is no timeline yet on what the province called last week “dangerous and difficult” work.
The overall water temperature in the Fraser “has been trending downward,” the province said, which is beneficial to the health of the fish.
The provincial and federal governments made a joint commitment recently to do everything possible to make sure the millions of salmon are able to reach their spawning grounds.
