Little Dry Creek and Cottonwood Creek Sediment Transport Data, 2012-2018, San Joaquin Watershed in the California Central Valley
Two tributary watersheds¬ Cottonwood Creek and Little Dry Creek¬ to the greater San Joaquin watershed, in California’s Central Valley were assessed for sediment and flow dynamics, between water years (Oct. 1 to Sept. 30) 2011 and 2019. The two systems deliver suspended sediment to the San Joaquin River below Friant Dam, California. Because these two creeks are directly down river of...

Bathymetric survey and stage-storage assessment of Quail Lake, Calif., collected in 2022
This bathymetric dataset provides an update to the stage-storage relation for Quail Lake (reservoir) located in the El Dorado National Forest, Calif. Bathymetric data was collected using a multibeam echo sounder to provide near-complete coverage and was merged with USGS 3DEP lidar to compute a DEM of the lake and near shore. The DEM was used to computed storage and surface area for a...
Little Rock Reservoir, California, 2022 bathymetric survey and stage-storage computations
This bathymetric dataset provides an update to the stage-storage relation for Little Rock Reservoir located in the Angeles National Forest, California. Bathymetric data was collected using a multibeam echo sounder to provide near-complete coverage and was merged with U.S. Geological Survey 3D Elevation Project lidar to compute a digital elevation model (DEM) of the reservoir and...
Bathymetry, Stage-Area, and Stage-Volume Tables for the Calaveras Reservoir, California, 2019 (ver. 2.0, March 2025)
Dataset contains reservoir bathymetry and shoreline topography up to dam crest elevation. Data were collected using small uncrewed aerial system (sUAS), multibeam sonar, and terrestrial lidar. Version 2.0 The multibeam sonar & terrestrial lidar data in version 2 was reprocessed for higher accuracy. 1-meter lidar data for 2020 from the USGS 3DEP program was used around the shoreline of...
Bed material grain size distributions for surficial samples from Iron Gate, Copco, and J.C. Boyle Reservoirs
This product summarizes the collection and analysis of bed material sample grain size distribution collected from the Iron Gate, Copco, and J.C. Boyle Reservoirs located in Northern California and Southern Oregon on the Klamath River. Samples were collected on June 16, 2020 from cores (less than 1m depth) and processed for the full size distribution.
Sediment grain-size data from the Klamath estuary, California
This data release includes grain-size measurements of sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath estuary, northern California. Samples were collected using a BMH-60 bed-material sampler deployed from a boat, or by hand trowel from subaerial or shallow-water (less than 0.5 m water depth) regions along the estuary margins...
Stage-Storage and Bed Material Data from the 2020 Upper Letts Lake Survey, California
On October 13, 2020 a survey of Upper Letts Lake was conducted where both bathymetric and terrestrial lidar data were collected. Additionally, six bed material samples and three core samples were collected to understand the characterization of the grain-size of the lake bed. Survey data were merged with an additional lidar dataset from the USGS 3DEP program to create digital elevation...
Loch Lomond Reservoir 2019 Survey Data
This dataset contains the digital elevation model from the bathymetric survey, along with the sediment samples, stage-area table, stage-storage table, and 20-ft contours of the reservoir.
Depth and Velocity Data in the Lower San Joaquin River, California, 2011-2014
This data release contains water depth, depth-averaged water velocity, and river stationing (based on 2012 ortho-imagery) in select locations in the Lower San Joaquin River, California, 2011-2014. Between 2011 and 2014, the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service (USFWS), collected approximately 105 channel cross-sections and multiple longitudinal...
State of the science and decision support for measuring suspended sediment with acoustic instrumentation
Acoustic instrumentation can be used to provide time-series and discrete estimates of suspended-sediment concentration, load, and sediment particle sizes in fluvial systems, which are essential for creating informed solutions to many sediment-related environmental, engineering, and land management concerns. Historically, scientists have developed relations between suspended sediment...

Sediment transport in two tributaries to the San Joaquin River immediately below Friant Dam—Cottonwood Creek and Little Dry Creek, California
Two tributaries to the greater San Joaquin River watershed, Cottonwood and Little Dry Creeks, in California’s Central Valley, were assessed for sediment and streamflow dynamics between October 1, 2011, and September 30, 2019. The two systems deliver sediment to the San Joaquin River below Friant Dam, California. Dams create downstream discontinuities in streamflow and sediment transport...

Storage capacity and sedimentation characteristics of Loch Lomond Reservoir, California, 2019
In May of 2019, Loch Lomond Reservoir was surveyed by the U.S. Geological Survey (USGS) in cooperation with the city of Santa Cruz to assess the current storage capacity and sedimentation rates in the reservoir. Survey methods combined sonar soundings to measure bathymetry and lidar scans with GPS data to measure near-shore topography and sediment bed samples to understand reservoir bed...

Physical characteristics of the lower San Joaquin River, California, in relation to white sturgeon spawning habitat, 2011–14
The U.S. Fish and Wildlife Service confirmed that white sturgeon (Acipenser transmontanus) recently spawned in the lower San Joaquin River, California. Decreases in the San Francisco Bay estuary white sturgeon population have led to an increased effort to understand their migration behavior and habitat preferences. The preferred spawning habitat of other white sturgeon (for example...
