GAGE - Water-stage recorder, crest-stage gage, water-quality monitor, and weighing bucket precipitation gage. Datum of gage is 1,501.00 ft above North American Vertical Datum of 1988. Prior to Nov 18, 1953, non-recording gage at site 20 ft upstream at same datum. Nov 18 to Dec 8, 1953, non-recording gage at same site and datum.

WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - WATER TEMPERATURE: October 2011 to current year.
INSTRUMENTATION - Water temperature sensor interfaced with a data collection platform with 15-minute recording interval.
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.
EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 28.1 °C, July 10, 2020; mimimum, -0.2°C, multiple days in winter months.
