REVISIONS HISTORY - Revisions: Gage height, discharge measurements, and discharge for the period Jan 12, 2018, to May 30, 2018, were revised on Mar 29, 2019, based on changes to gage height corrections, which affected discharge measurements 617-619, and computed discharge for the period.
SURFACE-WATER RECORDS
PERIOD OF RECORD - 1945-1995 (continuous-record discharge station), 1996 to 2013 (annual peaks only), 2014 to current year (continuous-record discharge station).
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,423.03 ft above National Geodetic Vertical Datum of 1929. Prior to Nov. 8, 1951, non-recording gage at same site and datum. Satellite and landline telemetry at station.

Records for water year 2016 are good except those for estimated discharges, which are poor. Records for water year 2017 are fair except those for estimated discharges, which are poor. Records for water year 2018 are good except for Jan 12 to May 30, which are fair, and those for estimated discharges, which are poor.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 1, 2013 to current year.
PERIOD OF DAILY RECORD - Water Temperature-October, 2013 to current year.
INSTRUMENTATION - Water temperature probe, anchored to streambed, since November, 2008.
REMARKS -

Historically, water temperatures below 0 degrees Celsius were not reported. Water temperature sensors now have the ability to accurately read water temperatures below 0 degrees Celsius. 

Cross-sectional water quality data is available upon request.

Interruptions in the record were due to equipment malfunctions or erroneous data. Records for water year 2014 water temperature are good, except for October 1 to May 28, which are poor. Records for water year 2015 water temperature are good. Records for water year 2017 are poor.
