<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The California Department of Water Resources (DWR), North Central Region Office (NCRO), Bathymetry Data Collection Section, conducted a bathymetric survey of the Sacramento River near Clarksburg for DWR's Delta Conveyance Office on behalf of the Delta Conveyance Authority. The purpose of this survey is for assessment of patterns of deposition and scour in the channel reach, bed stability and suitability for future intake planning. This measurement was collected after an early season high-flow event during which the flow was recorded to be between 50,000 to 80,000 cfs for three weeks.</SPAN></P><P><SPAN>• Survey Dates: January 31, 2023 to Febrauary 8, 2023 </SPAN></P><P><SPAN>• Instrumentation: Multibeam echo sounder and Inertially-Aided Post-Processed Kinematic (IAPPK) GPS procedures </SPAN></P><P><SPAN>• Density: 1 ft grid </SPAN></P><P><SPAN>• Horizontal Datum: North American Datum of 1983 (NAD83) (2011) California Coordinate System (CCS83) State Plane Zone III , USft </SPAN></P><P><SPAN>• Vertical Datum: North American Vertical Datum of 1988 (NAVD88), USft </SPAN></P><P><SPAN>• Data Epoch: 2017.5</SPAN></P><P><SPAN>• Related Datasets: Sacramento River at Clarksburg, 4/17/2019; Sacramento River 8/19/2019</SPAN></P><P><SPAN>• Involved Staff: Data collected and processed by NCRO Bathymetry and Hydrography sections </SPAN></P><P><SPAN>• Survey Responsible Charge: Jacob Wright, PLS (CA 8717) </SPAN></P><P><SPAN>Please contact the distributor for questions regarding survey control or QC checks.
