Stoney Creek spill leaves endangered fish either homeless or 'buried alive', biologist fears

Sediment spill earlier this month in Burnaby creek has damaged habitat for Nooksack dace, says Mike Pearson
Washouts along the banks of a fish-bearing creek in Burnaby may have seriously harmed a rare little fish that's so endangered in Canada it's found in only four streams, says biologist Mike Pearson.

The fish is the Nooksack dace, and one of those four streams — Stoney Creek on Burnaby Mountain — recently had a bank cave in at a City of Burnaby construction site, sending sand and silt into the water.

"I am seeing some serious impacts that I don't think have been fully appreciated," said Pearson, a registered professional biologist and leading authority on the small fish.

You might not be familiar with the Nooksack dace, but streamkeepers and environmentalists have been working since the 1990s to stop the freshwater fish from going extinct, even taking the federal government to court over its failure to protect it.
The sediment spill happened at a "vulnerable" time of year for the fish, said Pearson, when the dace have normally burrowed down between rocks and boulders to find a quiet spot to spend the winter.
