Environmental sleuths solve mystery of dead coho in a Courtenay creek

Before the fish started dying, the region was in a period of drought. Then, immediately after significant rainfall, the smolts turned up dead. All the evidence pointed to a chemical found in tire rubber.
In May of 2021, volunteers with a watershed-steward group in the Comox Valley came upon a startling scene: 65 dead juvenile coho salmon inside a collection box used to temporarily stall and count the fish on their journey to the ocean.

It was a big surprise, said Helmut Novak, vice-president of the Millard Piercy Watershed Stewards.

The group had installed the smolt fence and counting box at a new location that year, in Courtenay’s Piercy Creek, about half a kilometre downstream from the Comox Valley Parkway.
