This bathymetric survey was needed to help determine local hydraulics, future uses of Big Break, and to serve as a baseline for determining impacts of nearby wetland restoration projects. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.1, dated September 11, 2019.

<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 Big Break and surrounding creeks and sloughs. The data are needed to help determine local hydraulics, future uses of Big Break, and to serve as a baseline for determining impacts of nearby wetland restoration projects. The survey took place between January and July 2017 using single beam echo sounder technology.
