Water depth and depth-averaged water velocity in the lower San Joaquin River, California, collected generally near Greyson Bridge, the Old Fishermen's Club, and Sturgeon Bend. These data were collected using a SonTek M9 Acoustic Doppler Current Profiler (ADCP) May 10-11, 2012, and May 24-25, 2012.

The U.S. Geological Survey (USGS) installed acoustic bedload monitoring systems at four sites along the Trinity River below Lewiston Dam to record the noise generated by mobilized bed material, known as sediment generated noise (SGN) (Geay and others, 2017). The four sites are: Trinity River at Lewiston (TRAL, 11525500), Trinity River above Grass Valley Creek (TRGVC, 11525630), Trinity River at Limekiln Gulch (TRLG, 11525655) and Trinity River at Douglas City (TRDC, 11525854). These sites were selected because bedload measurements are frequently made at these locations during restoration flows as part of monitoring done by the Trinity River Restoration Program (TRRP). Monitoring took place in the spring of 2015,...

Problem Sediment transport is a serious concern in the upper Esopus Creek watershed. The creek is a well-documented source of sediment and turbidity to the Ashokan Reservoir, which is part of the New York City water supply system. During the last 2 decades there has been a series of stream stabilization and sediment reduction projects completed in the upper Esopus Creek watershed intended to reduce the suspended sediment load and turbidity levels delivered to the reservoir. During the last 7 years there has been a concerted effort to measure the effect of these projects on turbidity and suspended sediment. There is currently a large, long-term turbidity and suspended sediment study underway within the upper Esopus...

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 profiles, which comprised of nearly 150,000 streamflow-velocity measurements and 246,000 water-depth measurements in various reaches and subreaches of the Lower San Joaquin River between Orestimba Creek and Sturgeon Bend. The data collection locations in the Lower San Joaquin River were selected based on discussions with USFWS to...

This dataset is associated with the following Scientific Investigations Report: Marineau, M.D., Wright, S.A, and Lopez, J.V., 2020, Storage capacity and sedimentation characteristics of the San Antonio Reservoir, California, 2018: U.S. Geological Survey Scientific Investigations Report 2019–5151, 34 p., https://doi.org/10.3133/sir20195151.

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 Friant Dam, they become the most upstream source of sediment to the San Joaquin River below Friant Dam. Thus, is it important to assess their contribution to the San Joaquin system. Flow from each creek watershed, along with the San Joaquin River, was compared to continuously measured water surface elevations to quantify flow direction...

This data set contains estimates of bedload transport entering San Francisco Bay from the Sacramento-San Joaquin Delta. Bedload was estimated following the methods of van Rijn (1984) for the Sacramento River at Rio Vista (USGS 11455420) and the San Joaquin River at Jersey Point (USGS 11337190). The inputs the van Rijn (1984) equations included:bed-material particle size, bed-form dimensions, depth, and velocity. Bedload was estimated at 15-minute intervals from Water Year 2011 through Water Year 2020. A "low range" estimate and a "high range" estimate were made. The low-range estimate assumes plane bed conditions and uses only grain size to estimate a hydraulic roughness parameter. The high-range estimate incorporates...

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.

The centerline stationing begins in the center of the channel of the downstream receiving river; in the case of the lower San Joaquin River, the downstream receiving river is the Sacramento River. At this location, the River Kilometer (Rkm) is designated as Rkm 0. The geographical coordinates for each 1-kilometer Rkm station of the lower San Joaquin River (Rkm 0 – Rkm 187) are provided. The river centerline coordinate system was created using the wetted area of the river which was first digitized from 2012 National Aerial Imagery Program (NAIP) orthorectified aerial imagery of the Lower San Joaquin River.

Note: this data release is currently being revised and is temporarily unavailable. Dataset contains reservoir bathymetry and shoreline topography up to dam crest elevation. Data were collected using small unmanned aerial system (sUAS), multibeam sonar, and terrestrial lidar.
