Folsom Lake is now 102 percent of the historical average for this time of year, according to the California Department of Water Resources (DWR).
I had some concerns this might be due in part to snow melt so I did some checking.
DWR Reservoir Coordinated Operations Section Chief Boone Lek told me the models they run to calculate snow melt and inflow are not showing a significant amount of water coming from snow melting.
Even with the record setting warmth in the Sierra, it appears the snow pack is staying in place. Lek said there are a couple of reasons the warm temperatures aren't quickly melting the snow. First, he said "the density of the current snowpack is not primed for snowmelt." Second, the sun angle at this time of year is still fairly low and doesn't create a suitable environment for melting.
