Cinquini & Passarino Inc. conducted a bathymetric survey of portions of Old River, Grant Line Canal, Paradise Cut, Sugar Cut, Tom Paine Slough, Middle River and San Joaquin River for the Bay Delta Office and for Hydrologic Systems Incorporated for the South Delta Water Agency. The purpose of the dataset is to replace outdated and inaccurate data, help with the evaluation of sedimentation trends, improve numerical models, inform bathymetry changes near exports, and be a resource for informing management decisions such as dredging. This multibeam dataset is supplemented by additional singlebeam and topographic point datasets from the same date range. <\/SPAN><\/P>

\u2022 Survey Dates: Between December 12, 2021 and August 30, 2022. <\/SPAN><\/P>

\u2022 Instrumentation: Mutlibeam echo sounder echo sounder with Inertially-Aided Post-Processed Kinematic (IAPPK) GPS procedures and Real Time Kinematik positioning corrections. <\/SPAN><\/P>
