Quartzville Creek near Cascadia Oregon

An outside gage set-up at Quartzville Creek near Cascadia Oregon. Graduated staff plates installed at various heights to capture the range in water levels. Staffs are used to get river level readings hydrologic technicians need to calibrate electronic sensors.  The vertical grey metal pipe is a crest stage gage (CSG). CSG's have a cedar stick with a basket of loose cork at the bottom, when the river rises the cork floats, creating a highwater mark. The long-metal pipe mounted to the sheer bank houses the sensor cable to an electronic pressure sensor that measures gage height in feet.
