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...

Temperature loggers were placed on the ground (n=4) and hung in the air (n=2) near the upstream connection point of four Willamette River off-channel features (side channels and alcoves) to assess timing and discharge conditions when these four off-channel features were inundated at the upstream end with flow from the main channel. Temperature readings indicate that the upstream end of an off-channel feature is inundated when the ground temperature sensor does not match nearby air temperature readings, indicating the ground sensor is submerged by river water. Temperature loggers were installed from late May through mid-November, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000...

Water quality point measurements were collected by the U.S. Geological Survey within the main channel Willamette River and its off-channel features in the summer and autumn of 2015 and 2016. All measurements include location, time, temperature, and depth below water surface, while most also include specific conductivity, dissolved oxygen, and pH.

Water quality point measurements were collected by the U.S. Geological Survey along the lower Willamette River near the cities of Lake Oswego and Wilsonville, Oregon, as well as the lowest two kilometers of the Clackamas River, Molalla River, and Johnson Creek. These measurements were collected in the main channel and off-channel features on discreet dates from April through October of 2017. All measurements include location, time, temperature, and depth below water surface, while many also include specific conductance, dissolved oxygen, pH, and turbidity.
