(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Rating equation is based on 4-day running means.  Irrigated agriculture and levee protection strongly limit usefulness of this site.
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)
