Rising water temperatures threaten fish populations

The Durango Herald discusses how rising water temperatures threaten fish populations. Drought, lower flows pose serious challenges to aquatic life in Southwest Colorado.

With rising temperatures and prolonged drought, Southwest Colorado’s rivers and streams are increasingly running lower and warmer, creating an uncertain future for fish and other aquatic life.

“Fish don’t sweat,” said Jim White, an aquatic biologist with Colorado Parks and Wildlife. “So if you’re a cold water fish, and the water temperature keeps rising on you, you don’t have a lot of options to cool off.”
