This version of lookup focuses on patterns between the Sacramento River ("Sacramento"), the Colorado River ("LeesFerry"), spring bivariate ENSO index ("EnsoMAM"), and winter bivariate ENSO index ("EnsoDJF").
The data is described in detail below.
"Sacramento" is a water year time series of unimpaired runoff, or full natural flow, for the Sacramento River. The data has been transformed into rank-percentiles. The series is the sum of natural flow from four river gauges: Sacramento River at Bend Bridge, Feather River at Oroville, Yuba River near Smartville, and American River at Folsom Lake. This index is also known as the "Four River Index" or "Four Basin Index".
"LeesFerry" is a water year time series of natural flow for the Colorado River. The data has been transformed into rank-percentiles. The data is calculated from the Lee's Ferry river gauge. This gauge measures the Colorado River streamflow from the Upper Colorado River basin. Source.
"EnsoMAM" is the Bivariate ENSO Timeseries (BEST) from March through May (Smith and Sardeshmukh 2000). This index measures ENSO variability. See here for further discussion.
"EnsoDJF" is the Bivariate ENSO Timeseries (BEST) from December through February (Smith and Sardeshmukh 2000). This index measures ENSO variability. See here for further discussion.
