Bathymetric change grids covering the periods of time from 1992 to 1998 and from 1994 to 2004 are presented. The grids cover a portion of the Sacramento River near Rio Vista, California, extending partially upstream on Cache and Steamboat sloughs by the Ryer Island Ferry, as well as continuing up the Sacramento River towards Isleton. Positive grid values indicate accretion, or a shallowing of the surface bathymetric surface, and negative grid values indicate erosion, or a deepening of the bathymetric surface. Bathymetry data sources include the U.S. Army Corps of Engineers, California Department of Water Resources, and NOAAs National Ocean Service.
These bathymetric change grids were created for use in a pilot study to explore bathymetric change in the Sacramento-San Joaquin Delta region. The bathymetry of the Delta affects the flow of water and sediment throughout the system and is a basic control on levee stability, habitat distribution, and water quality. Delta bathymetry is dynamic, responding to both natural and human-induced changes in the environment. Assessment of future Delta conditions is aided by an understanding of how its bathymetry has changed in the past.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

No formal attribute accuracy tests were conducted.
No formal logical accuracy tests were conducted.
Data are considered complete for the information presented. Geographic boundaries of the interpolations are determined by the limits of source data used. For example, the USACE 2004 survey does not extend as far upstream on the Cache and Steamboat sloughs as do the USACE 1998 and the NOAA 1992 surveys.
Data are as accurate as source data used, no further tests were conducted, and no claims are made to accuracy.

A 1998 bathymetry survey from the U.S. Army Corps of Engineers covering the area of interest was downloaded from the DWR database and then converted to a bathymetric surface using the ArcGIS TopoToRaster module (ESRI, 2015). Hand-drawn contours were created to constrain the data interpolation, and an interpolation boundary was defined.
