Sockeye salmon are migrating up B.C.'s Fraser River right now, but the water is so warm the fish may die before they have the chance to spawn.

Don’t treat the river like a personal bathtub. It’s a message Squamish conservationists are putting forward after they found man-made dams blocking pink salmon from their spawning grounds.

Drought and high temperatures have dried the creek and caused thousands of pink salmon and Dolly Varden to die before they could spawn. The event raises questions about vulnerability of area salmon streams to climate change, and for local residents food security.
