Station Notes
USGS gage previously located
300 feet downstream, Baker River at Concrete, WA (1213500), was
discontinued on May 1, 2009.
This station may be affected by
backwater from the Skagit River, often when the stage at Skagit
River near Concrete gage exceeds 29 feet. Please use the data
for these periods with caution.
The datum of the gage has been
determined to be 174.08 ft above National Vertical Datum of 1988. To
obtain stream water-surface elevation values in NAVD 1988, add 174.08
ft to gage height values.
