Lithologic classifications of river gravels in the Sauk River watershed The rock type, or lithology, of river gravels provides information about the bedrock source area of that material, and can act as a tracer to help assess relative gravel contributions from tributaries or distinct valley deposits. Between July 2020 and August 2021, gravels at 29 sites in the Sauk, Suiattle and White Chuck rivers were collected and sorted into simple lithologic categories. The data release here provides a summary of those raw data. These data support analyses presented in Anderson et al. (2022). Each row of the attached comma-separated value (CSV) file reports masses, in kilograms, of gravel in various lithologic categories for a given sample. Each sample consisted of 25-30 kg of gravel with intermediate-axis...

These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs, and surficial sediment samples. The interpretation of the seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of...

Daily mean streamflow was estimated by developing a regression relationship between each partial-record site and the index site for water years 2012-2019. These data are intended to provide daily mean streamflow estimates at partial-record sites as part of a larger study (Clark and others, 2021) to estimate sediment loading for each site.
