(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)

Notes:

Discharge calibration is based on comparision of monthly means, minima, and maxima from an ground comparision station in the region with adjustment for different contributing areas

Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)

(For U.S, sites, nearby ground station discharge may also be shown)
