<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 of Mildred Island. The data is needed for improving the understanding of water circulation, turbidity and salinity trapping for drought management and endangered species mitigation purposes. The survey took place between May 8 and June 6, 2018 using single beam echo sounder technology. The data were positionally corrected using Inertially Aided Post-Processed Kinematic (IAPPK) procedures. </SPAN><SPAN>The 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><P><SPAN>Nearby datasets: The adjacent portions of Middle River and Empite Cut up to the south breach of Mildred Island were surveyed in June, 2011.</SPAN></P></DIV></DIV></DIV> |
