This station provides data on stream stage/discharge, water and air temperature, CDOM and conductivity. The renovation included upgrades to a new data logger and communication system to achieve direct real-time online communication and the installation of a new water temperature thermocouple.  Finally, a new bio-wiper fluorometer was deployed into an aquarium into which stream water is pumped hourly to be able to enable consistent anti-fouling proof measurement of colored dissolved organic matter in the stream water.
