Ice-cover determination: 5 yr recurrence flood: 24116 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow or ice, 2 = Normal flow, 3 = Flood, 4 = Major Flood 21993 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Mandi Plain (2839100)         Contributing Area:   sq mi 20886 sq km
(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Calibration to nearby ground station hasbeen accomplished. Accuracy Estimate:  Fair Pre-February 2005 high M values not explained.
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data) Discharge values before may not be realistic.
(For U.S, sites, nearby ground station discharge may also be shown)

Discharge is estimated via a rating equation directly from the remote sensing data (M/C ratio) shown below.
Explanation:   Green line records upwelling microwave emission from within 5 km radius of a calbration land target; blue line is emission from within 5 km radious of the measurement target centered over the river.
Brown line is their ratio (M/C; scale on right) and is used to estimate river discharge via a rating equation.
