ADCP Data in Support of Water and Suspended-Sediment Flux Measurements at the Golden Gate, 2016-2017
Field observations of water and suspended-sediment fluxes at the Golden Gate were made over one ebb tide and one flood tide on three occasions: 1) 21-22 March 2016, following a large storm event that triggered the first flow into Yolo Bypass flood control structure since 2011; 2) 23 June of 2016, during a period of low freshwater inflow and 3) 27-28 February 2017, following several large storms of the wettest winter in northern California in recorded history. On each occasion, flux of water and suspended sediment were estimated using data from a boat-mounted acoustic Doppler current profiler. This instrument provided high-resolution velocity and acoustic backscatter (ABS) data at a cross-section (“transect”) near...
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.
Dataset contains a comma delimited (csv) file reservoir stage-area and stage-volume tables. Stage is provided in elevation (in ft NAVD 88) in the first column in 0.1 ft increments. Reservoir surface area is in acres and volume in acre-feet at each of those 0.1 foot increments.
These files are 10-ft contours generated from the 2019 bathymetric and topographic digital elevation model (DEM). The contours were smoothed and small contours and fragments generated from the DEM were removed to provide a simple set of contours for visualation purposes. Also included in this set are contours representing the spillway crest elevation (759.01 ft NAVD 88) and the dam crest elevation (775.6 ft NAVD 88).
Dataset contains reservoir bathymetry and shoreline topography up to the dam crest elevation. Data were collected using multbeam sonar, terrestrial lidar, and small unmanned aircraft systems (sUAS). Data were merged into a single digital elevation map (DEM). Areas outside of the dam crest elevation contour were removed. Data are presented in two raster file formats: ascii and tiff.
