Data for the USGS streamgage on the Paria River at
Lees Ferry, Arizona, USA, July 2004 through September 2006.
(a) Time series of streamfl ow, SSCs from samples, and SSCs
calculated from weight densities of suspended sediments and
dissolved solids measured using the Double Bubbler for a
storm in January 2005; (b) scatter plot of measured SSCs from
samples and those calculated from the Double Bubbler.
Streamfl ow and sediment data are instantaneous samples, and
the Double Bubbler SSC values, calculated from weight
densities, are from measurements made at 5-minute intervals.
