FILE - In this May 26, 2011 file photo, arns are surrounded by the flooded Musselshell River west of Harlowton, Mont. For 2014, a hefty mountain snowpack in the Northern Rockies has driven down the summer wildfire potential and bumped up prospects that farmers in most of Montana and Wyoming won’t go dry. As for flooding, government forecasters say the coming weeks will make all the difference. A relatively even warm-up would keep streams and rivers in check. Too much warm weather and flooding could again threaten downstream communities. Late season snows three years ago led to flooding in the Missouri River basin that swamped hundreds of thousands of acres across the Upper Midwest. (AP Photo/Lisa Kunkel, File) less
