(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 comparison of 4-day running means. Rating requires adjustment for low flow. 
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)
