 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><DIV><P><SPAN>The California Department of Water Resources (CA-DWR), North Central Region Office (NCRO), Bathymetry Data Collection Section, conducted a targeted singlebeam bathymetric survey on the Sacramento River near Clarksburg for the Delta Conveyance Office. This singlebeam data is not intended to provide enough points to interpolate a surface, the main purpose of the data is to serve as an independent check on multibeam data collected on the same date. The survey was conducted in tandem with the multibeam survey with the singlebeam vessel trailing just beyond the turbulent influence of the lead vessel, about 100 yards. The echosounder was operated 200 kHz, and may penetrate slightly further into the bed substrate than the 455 kHz multibeam sonar. <\/SPAN><SPAN><SPAN>The data were collected in NAD83 (California State Plane Zone III coordinate system) and NAVD88 datums.<\/SPAN><\/SPAN><\/P><P><SPAN>\u2022 Survey Date: April 17, 2019 <\/SPAN><\/P><P><SPAN>\u2022 Instrumentation: Singlebeam echo sounder with Inertially-Aided Post-Processed Kinematic (IAPPK) GPS procedures. <\/SPAN><\/P><P><SPAN>\u2022 Point Spacing: about 1 Foot<\/SPAN><\/P><P><SPAN>\u2022 Horizontal Units: US Foot<\/SPAN><\/P><P><SPAN>\u2022 Vertical Units: US Foot<\/SPAN><\/P><P><SPAN>\u2022 Related datasets: Sacramento River at Clarksburg (multibeam), April 2019<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
