{ "currentVersion": 11.3, "serviceDescription": "

The California Department of Water Resources (DWR), North Central Region Office (NCRO), Bathymetry Data Collection Section, conducted a bathymetric survey of Grizzly Bay as part of the Delta Wide Bathymetry Program. The main purpose of the data is to help complete bathymetric datasets of Suisun Marsh and allow for relevant comparisons. Due to conditions in the field, the extents of this multibeam dataset were limited and the rest of the bay was canvassed in a corresponding singlebeam survey.<\/SPAN><\/P>
