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 NOAA’s National Ocean Service. Purpose: 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.
