PERIOD OF RECORD - October 2011 to current year. Archived data September 2001 to September 2011.
INSTRUMENTATION - A Campbell Scientific model 107 water temperature thermistor, installed in 2001 is used as backup for temperature. A FTS Digitemp was installed 8/29/2016 and is used as primary probe. Temperature is maintained by the U.S. Army Corps of Engineers and connected to the CR10 data-logger. Unit values are recorded at 15-minute intervals with automatic data retrieval. Recording equipment is housed in the gage structure with the stage-recording equipment. The temperature probe is located at the orifice.
