Lacy, J.R., Ferreira, J.C.T., Dailey, E.T., Dartnell, P., Drexler, J.Z., Allen, R.M., and Stevens, A., 2020, Sediment transport and aquatic vegetation data from three locations in the Sacramento-San Joaquin Delta, California, 2017 to 2018: U.S. Geological Survey data release,


Bed sediment samples were collected in Lindsey Slough in April 2017, and Middle River and the Mokelumne River in March 2018, to analyze for sediment properties, including bulk density, particle size distribution, and percent organic carbon. Sediment samples were collected within the vegetation with push corers deployed from a small vessel, and in the unvegetated channel with a Gomex box corer, which was subsampled with three push cores per Gomex core. Data are provided in a comma-delimited values spreadsheet. These data were collected as part of a cooperative project, with the USGS California Water Science Center and the California Department of Fish and Wildlife, on the effects of invasive aquatic vegetation on sediment transport [...]

These data will be used to inform studies of sediment resuspension and transport in areas with increased aquatic vegetation in the Sacramento-San Joaquin Delta. These data are intended for science researchers, students, policy makers, and the general public.
