“In the Firehole River that slashes through the wild grasses and woods of Yellowstone’s west side, the trout began to take notice. As the water warmed on that early July day, the levels of dissolved oxygen dropped. The fish – rainbows, with their bright crimson lateral slash, and brown trout, with their multicolored spots – began to panic.” Rick Tosches paints a gloomy but detailed picture of what an over-warm summer is doing to the fish of Yellowstone National Park. Of course what is not being talked about as often are the thousands upon thousands of miles of trout streams outside of the park where trout are also being decimated by heat. In the Denver Post.
