Water-surface elevations were recorded by submerged pressure transducers in Spring, 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. The water-surface elevations were surveyed by using a real-time kinematic global positioning system (RTK-GPS) at each pressure sensor location. These water-surface elevations were logged over a small range of discharges, from 4,600 cubic feet per second to 10,800 cubic feet per second at Harrisburg, OR. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple datasets that will be released for this...

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...

Water-surface elevation measurements were collected in Spring, 2015 along the upper Willamette River, Oregon, between Harrisburg and Corvallis. These surveys were collected over a small range of discharges, from 6,900 cubic feet per second to 8,300 cubic feet per second, using a real-time kinematic global positioning system (RTK-GPS) on a motorboat at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

This digital dataset, compiled from previously published andunpublished data sources, contains a personal geodatabase andraster data of features related to the repeated inundation of theWillamette Valley and Portland basin by Missoula Flood waters inLate Pleistocene time. The feature classes contained within theWill_Valley geodatabase are called 'erratics', representing thelocations of ice-rafted erratics; 'contours', representinginundation levels associated with stratigraphic evidence ofrepeated floodings; and 'geology', representing the generaldistribution of Missoula Flood deposits. A stand-alone tablewithin the geodatabase contains geologic unit descriptions forthe geology polygons contained in the 'geology'...

River bathymetry and stream velocity measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) and acoustic Doppler current profiler (ADCP) on a motorboat while transecting at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

Water-surface elevation measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene to Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) on a motorboat traveling "on plane" along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort.

This dataset includes bird species, invertebrate order and family, sample identification codes, capture date, latitude, longitude, habitat, site name, bird age, total mercury concentrations in bird blood, and methylmercury concentrations in whole body aquatic invertebrates.

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...

This digital dataset was compiled from newly released U.S.Geological Survey 10-meter digital elevation model (DEM) data,along with stream and transportation coverages previouslypublished on the internet. This report consists of a digitalrepresentation of the physiography of the Willamette Valley.Contained in this dataset is: 1) 10-meter DEM data for the entireWillamette Valley; 2) the ARC/INFO grids used to create the colorshaded-relief and gray scale shaded-relief images; 3) thenecessary data ARC/INFO data to used to plot these data; and 4)several reports detailing the data formats (this docuement) andproducers used to create these datasets. The scale of theoriginal 10-meter DEM data should not be violated. Any...

A record peak flow in February of 1996 caused the Willamette River and its major tributaries to flood. This map was created to delineate the inundated areas near the mainstem and major tributaries of the Willamette River. Complete FGDC metadata is available from US Army Corps of Engineers, Portland District. Updated through the Goal 5 process, the State of Oregon mandate for identifying areas for potential habitat protection. Downloaded from Metro's RLIS Discovery site 7/2/2012.

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.

This is a spatially referenced water quality dataset for the Lower Columbia River in July 2016. The data were collected using the FLAMe water quality mapping platform having a YSI EXO2 multiparameter sonde, and an LGR greenhouse gas analyzer.
