This site uses multiple sensors, and possibly sensor types, to measure gage height. The final usable published data series is presented as the Primary Sensor. The Secondary and Tertiary Sensors are used to fill in for the Primary Sensor when the Primary Sensor is either damaged or less accurate.

The datum of gage has been determined to be 1313.71 feet above NAVD 1988. To obtain stream water-surface elevation values in NAVD 1988 add 1313.71 feet to gage height values.

Discharge is only calculated above a base discharge of 350 cfs.
