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 The purpose of the dataset is to replace outdated and inaccurate data, help with the evaluation of sedimentation trends, improve numerical models, inform bathymetry changes near exports, and be a resource for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 singlebeam dataset is meant as a supplement to the related multibeam and topographic point datasets from the same date range.<\/SPAN><\/SPAN><\/P>
