The Pacific Salmon Commission is concerned about historic temperatures in the Fraser River.
It’s reaching 19 degrees Celsius, almost 4 degrees higher than normal.
That’s just one degree below the point where experts predict there could be damaging effects on fish.
Chief Biologist Mike Lapointe says the weather could have an impact on sockeye and pink returns.
“B.C.’s expectation is for approximately 6.8 million Fraser sockeye returns, that is the median forecast; there is quite a range about that, because there is an uncertainty about the survival of these fish. And then also Fraser pink salmon, I believe the forecast is 14 million for Fraser River pink salmon returning, and those returns are certainly large enough to have sustainable fisheries, it’s just a question about what the river conditions will do.”
Lapointe says all they can do it make sure there’s enough fish to reach the spawning grounds.
A number of angling bans have been put in place across the province.
While some rain is in the forecast this weekend, the BC River Forecast Centre says we need to see a significant event before river levels get back to normal.
Dave Campbell says the hot and dry weather, along with the low snow pack, is causing unusually low river levels.
“On the order of hundreds of millimeters short of water in some of those areas, so a little bit of rain is probably not going to make a huge difference, we really need to get sustained rain for a broader period. Certainly it will ease things if we were to get some rainfall, but I think to really improve things, we need to get some significantly wet weather.”
The South Coast, Lower Fraser and parts of the interior are under level 3 drought conditions, while Vancouver Island is seeing the most extreme conditions at level 4.
