Map of streamgages in the GAGES2 dataset with greater than 10 years of discharge data and snow water equivalent

Map of gages in the GAGES2 dataset with >10 years of discharge data (see Falcone, 2011). Dots are colored by the mean annual maximum Snow Water Equivalent (SWE) for the watershed draining to the gage. There is a general spatial pattern in snowpack across these watersheds, where mean annual maximum SWE is highest in northern regions and lowest in southern regions.
