Yosemite's Water Flow

The Merced River has more than doubled in volume (to more than 800 cfs at the Pohono gauge) over the past 4 days due to the warming that has followed Monday's snowstorm.
In addition to good flow from Tenaya, Yosemite and Bridalveil Creeks, we also see water now reaching the river from Sentinel, Eagle, Ribbon and Royal Arch Creeks. Horsetail Creek is flowing on the surface into Wosky Pond, though the pond isn't full enough to connect to the river on the surface.
Table Rock is still high and dry and the Merced has a long way to go to reach full snowmelt volume. Depending on how the next 4-6 weeks continue to warm, it should at least double or maybe triple its current flow. Splish-splash!
