<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 bathymetric survey on the Sacramento River from the confluence with the American River to Courtland for the Delta Conveyance Office. The main purpose of the data is to understand river bed elevations and dynamics for planning of diversion intakes on the Sacramento River when the river is carryin 18,000 cfs +/- 5,000 cfs. An additional measurement in April 2019 provides a comparison during high flow condtions. This version of the data combines the bathymetry with the best available LiDAR.</SPAN></P><P><SPAN>Bathymetry:</SPAN></P><P><SPAN>• Survey Dates: July 29 - August 19, 2019</SPAN></P><P><SPAN>• Instrumentation: Multibeam echo sounder with Inertially-Aided Post-Processed Kinematic (IAPPK) GPS procedures</SPAN></P><P><SPAN>• Density: 1 ft grid </SPAN></P><P><SPAN>• Datum: NAD83 (California State Plane Zone III) horizontal (Epoch 2017.5), NAVD88 vertical </SPAN></P><P><SPAN>• Related datasets: April 2019 NCRO bathymetry dataset collected at 70,000 cfs from Clarksburg to Randal Island on the Sacramento River</SPAN></P><P><SPAN /></P><P><SPAN>Lidar: </SPAN></P><P><SPAN>• Survey Dates: Lidar data for the entire Delta was collected in 19 missions from December 19, 2017 through January 21, 2018</SPAN></P><P><SPAN>• Instrumentation: Leica AL580-HP</SPAN></P><P><SPAN>• Density: 0.5 m grid </SPAN></P><P><SPAN>• Original Datum: NAD83 (California State Plane Zone III) horizontal (Epoch 2017.95, NAVD88 vertical</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
