Summary
River bathymetry measurements were collected in 2017 and 2018 along the Willamette River, Oregon, between Eugene and Newberg. These data were collected to complement a bathymetric lidar dataset collected in 2017 for the same section of river. In many deeper segments of the river channel, bathymetric lidar did not produce measurements of river bathymetry. To fill gaps in the bathymetric lidar dataset, USGS combined bathymetry data previously collected in 2015 and 2016 with newly collected survey data from 2017 and 2018. The bathymetric survey data acquired in 2017 and 2018 focused on filling gaps within the 2017 bathymetric lidar dataset. Bathymetry data were collected using a network based real time kinematic global positioning system [...]

The bathymetric survey data acquired in 2017 and 2018 focused on filling gaps within the 2017 bathymetric lidar dataset. Bathymetry data were collected using a network based real time kinematic global positioning system (RTK-GPS) and single-beam sonar mounted to a motor-boat transom. This documentation describes a csv file containing the X, Y, and Z coordinates and associated quality-control metrics for data collected along the Willamette River between 2015 and 2018.

Bathymetry from single-beam sonar and RTK-GPS collected between 2015 and 2018 were compiled to supplement missing spatial data not acquired during a 2017 lidar survey (Quantum, 2018). These data will enable interpolation of a continuous topographic surface, or digital elevation model (DEM), and support future multi-dimensional hydraulic modeling and geomorphic change assessments
