(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Site is a reservoir and signal records reservoir level changes, not discharge or runoff
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)
(For U.S, sites, nearby ground station discharge may also be shown)
