You may want to reschedule that Montana fishing trip for now. High water temperatures caused by sizzling summer weather has prompted state officials to close fishing from noon to midnight on some of the West’s most celebrated trout streams. The current closures stretch over 538 miles of water on the Bitterroot, lower Gallatin, east Gallatin, lower Madison, Sun, Dearborn, Smith, and Yellowstone River, downstream from Big Timber. Other waters approaching the restricted-fishing threshold, according to this Rocky Mountain News article, are the Missouri River below Holter Dam, the Boulder River tributary to the Yellowstone River, portions of the Big Hole River, Rock Creek, and the Thompson and Blackfoot rivers.,1299,DRMN_85_4884860,00.html
