Idaho Fish Report

A portion of Clear Creek and Fish Creek were treated last year with rotenone to remove rainbow trout and rainbow-cutthroat hybrids before they could expand throughout the drainage and threaten the conservation population of Bonneville cutthroat trout. The target area included Clear Creek, from its confluence with Fish Creek downstream two miles to the Narrows, as well as Fish Creek, from its confluence with Clear Creek upstream about five miles. All other stream reaches within the drainage, including Fremont Indian State Park, were unaffected by the treatment and still have abundant numbers of cutthroat trout. Cutthroat trout have been restocked in the treatment area, but they are still small (likely less than 8 inches).
