The March 30, 2015 snow map is the last one for the season. For those wanting to continue monitoring the conditions, the NRCS publishes a daily map, or you can browse the other NRCS reports. The basin comparison graphs show the current snowpack, how it compares to the normal peak, and if and how much of the snow has melted. The graph also has comparable years.
