This bathymetric dataset is intended to be used as a limited assessment of change within the Clifton Court Forebay by replicating selected transects from a previous more comprehensive survey conducted in 2016.
The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.1, dated September 11, 2019.

<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 bathymetry survey of Clifton Court Forebay (CCF) at the request of the Bay Delta Office and Delta Field Division. DWR conducted a single-beam sonar survey in CCF in March 2018. This survey was intended as a more limited assessment of change by replicating selected transects from a more comprehensive 2016 survey. The shallow regions of Clifton Court Forebay were sampled to determine general bed elevation trends since 2016, and to determine whether further measurements are necessary. The singlebeam field survey was completed on March 14, 2018. A separate, February 2018, multibeam dataset of the apron and scour hole is available. </SPAN><SPAN>The original field survey data were positonally corrected using Real-Time Kinematic (RTK)GPS. </SPAN><SPAN>The original field survey data were collected in NAD83 (California State Plane Zone III coordinate system) and NAVD88 datums.</SPAN></P><P><SPAN>• Horizontal Units: US Foot</SPAN></P><P><SPAN>• Vertical Units: US Foot</SPAN></P></DIV></DIV></DIV> |
