Summary

Water surface elevations within seven Willamette River off-channel features (OCF; alcoves and side channels) were measured using submerged pressure transducers. Transducers were installed from late May through mid-October, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000 cubic feet per second at Salem, Oregon (USGS gage 14191000) and 3,500 to 17,500 cubic feet per second at Harrisburg, Oregon (USGS gage 14166000). Pressure transducer sensor depth was measured at all seven sites. For five of the sites, pressure transducer sensor depths were converted to water surface elevations by surveying the water surface at each transducer with a real-time kinematic global positioning system (RTK-GPS). Additionally, [...]

Purpose

These water depth measurements were collected to relate changes in main channel discharge with water quality conditions in off-channel features. Data collected by U.S. Geological Survey (USGS) in 2016 indicate that water quality conditions in off-channel features vary, depending on volume and persistence of surface water connections between off-channel features and well-mixed main-channel water.
