The California Department of Water Resources (CA-DWR), North Central Region Office (NCRO), Bathymetry Data Collection Section, conducted a bathymetric survey of Little Mandeville Island for the Bay Delta Office (BDO). The main purpose of the data is to replace outdated and inaccurate data, improve innudation mapping throughout the Delta and help with the evaluation of restoration proposals nearby. This dataset is from kayak-mounted singlebeam sonar for the northwest corner of the Island and is meant to supplement a grid of multibeam strips for the remainder of the Island. <\/SPAN>The data were collected in NAD83 (California State Plane Zone III coordinate system) and NAVD88 datums.<\/SPAN><\/SPAN><\/P>
