Discharge: 5852 m3/sec Status: 1 (1, low; 2, normal flow; 3, moderate flood, r >1.5 y; 4, major flood, r >5 y)
7-day Runoff 303.9 mm #N/A (7-day runoff compared to 20 y average for this date, 2002-2021)
Flood Magnitude: 0.0 Scale of 0-10 Flood Magnitude Defined Technical Summary
Notes: 7-day forward weighted moving average is applied. Geolocation correction, commencing April 1, 2012: 0
Low flow is 20th percentile discharge for this day, 2003-2013.
Log Pearson  III computes recurrence intervals from 22 years of record (1998-2019) Change in 10 yr flood discharge (2010-2021 /1998-2009): 116.3%
Mean discharge 5695 m3/s
Annual Runoff (percent of mean, 1998-2021) Mean Runoff 18019 mm
Major Floods
Change in Annual Runoff (2010-2021/1998-2009): 84.7% 10 = Flood of Record
