Melting snow fills the Tuolumne RiverWhile the snow at high elevations in Yosemite is melting rapidly, there’s still plenty around,enough to keep the water flow high as it melts. While the snow at high elevations in forecast calls for warmer temperatures Sunday and Monday, so the water volume in Yosemite Valley should increase—maybe not to the level we saw last weekend, but close. After that, temperatures are supposed to cool down again, so that may be the end of the highest water this year, as most of the snow will be gone soon.
