Grain-size data for sediment samples collected in Whiskeytown Lake, northern California, in 2018 and 2019

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-07-08T00:00:00Z
This data release includes grain-size data from sediment samples collected in submerged and subaerial regions in Whiskeytown Lake and around the reservoir margin. Sediment samples were collected using a sampler deployed from a boat or by hand from locations exposed above the water surface. Sediment grain size was analyzed at the USGS laboratory in Santa Cruz, Calif. The full data set is reported here, but users should be aware that due to instrument error the data between approximately grain sizes from 0.040 to 0.063 mm may be incorrect and have unknown degrees of uncertainty. Proportions of gravel, sand, silt, and ratios among these size fractions, are considered accurate.
