Digital elevation model and single beam sonar data from the McKenzie River, Oregon, 2021
In 2021, the USGS 3D Elevation Program (3DEP) funded the collection of topo-bathymetric lidar (sometimes referred to as "green lidar") on the McKenzie River, Oregon. As part of this acquisition, lidar data were collected starting on the McKenzie River below Trail Bridge Reservoir and extending downstream roughly 125 km to its confluence with the Willamette River. Bathymetric lidar produced measurements of river bathymetry in areas of the McKenzie River channel that were generally less than 3 m in depth but did not produce measurements in deeper areas of the river. To fill the gaps in the topo-bathymetric lidar dataset (commonly referred to as "voids"), the U.S. Army Corps of Engineers funded USGS to collect boat-based sonar data and integrate the sonar and lidar data into a single digital elevation model (DEM). The datasets within this data release includes a) the final DEM of the river channel incorporating sonar and lidar data and b) underlying boat-based sonar data used to interpolate the lidar voids and c) metadata describing methods used to produce the datasets.
