** ADVANCE FOR MONDAY, SEPT. 2 ** River guide Ross Freeman pulls on the oars as he paddles on the Skykomish River, Aug. 3, 2007. Freeman, associate director of conservation for the Northwest regional office of American Rivers, has been rafting for 15 years. While he doesn't expect the Skykomish to run dry anytime soon, he said that as more winter precipitation arrives as rain instead of snow, there will be less snowpack to keep water levels high enough to be raftable.
