This singlebeam project is part of the Suisun Slough, December 2018 dataset and contains a few limited transects in Grizzly Bay. There were significant sand waves in these transects that may be temporally dynamic and therefore probably inappropriate for modeling work -- sand waves have been smooothed in this dataset. The related Grizzly Bay rough dataset features the original sand waves.
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.
DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.
