Whitefish belly up on my right. Few minutes later, another one off the nose of the boat. It’s early fall on the South Fork of the Snake River in Idaho. The cool release following summer heat is a relief, but it didn’t come soon enough in this cottonwood-lined corridor. Dead whitefish are the fatal sign and the sight is alarming. Whitefish are a river’s canary in a coalmine. If something is wrong with whitefish, something is wrong with the river.
