This is 100% of the waterflow of Lower Yosemite Falls at the time of the photo. For a point of comparison, take a look at my 2003 photo of the exact same waterfall from a wider perspective, from March 03 by clicking here. It's safe to say the waterfall takes on a different perspective during October than what it holds in the spring. As you look at the 2003 photo, remember I took them both from the same place.
