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

Notes:

Discharge calibration based on comparison of monthly means (maximum flows, minimum flows and mean discharge) from a station in the region

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

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