These transducers are positioned at approximately -25 ft gage datum. Upstream Oregon side. Transducers are wired directly into the UVM console which is located in the gage house, cables are threaded through the underside of the dock. The UVM's SDI-12 output sends velocity data in feet per second to the CR10. The transducer pipe brackets are accessible from a wood boardwalk which is below the road surface of the dock.
Data logger records data from sensors.
USGS computer downloads data from data logger on a daily schedule. The bolt is 3 ft streamward from the NW corner of the building which houses the gage, established 1966. This RP can be used as a tape down to water surface. 0.52 ft above mean sea level. Hazards occur from floating debris, particularly at high flow.
