The Geological survey Im sure is correct. I was making a comparison to what I have seen in the last 14 years. The falls are alot smaller and this is the first May that we have seen the sandbar at Swinging bridge uncovered so much that people could walk to it without going above the knees. There should be water by the end but who knows what July will be. Hopefully, there will be some thunderstorms in the high country.
Water levels are high with seasonal waterfalls flowing well.
The US Geological Survey maintains stream gages with realtime data along the Merced River just above and below Yosemite Valley.
