PERIOD OF RECORD - October 1939 to current year.
GAGE - Water-stage recorder. Elevation of gage is 2,027.75 ft, referenced to the National Geodetic Vertical Datum of 1929.
REMARKS - Flow increased during irrigation season by water from St. Mary Canal which diverts from the St. Mary River near Babb.

Numerous diversions for irrigation occur upstream from station.
