Data

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.

This data release includes a file geodatabase with high-resolution geospatial products that illustrate the geomorphology and various land-surface parameters along a 313-kilometer segment of the mainstem Klamath River corridor downstream of Iron Gate Dam, CA. The geospatial products were derived from topobathymetric elevation data collected to document baseline topography and bathymetry before the

California's State Water Resources Control Board (SWRCB) wishes to quantify how water and constituents introduced via the outflow from the Spring Creek Diversion Dam mix with water within Keswick Reservoir. Of primary interest is the degree of dilution that exists when this introduced flow reaches the main stem of Keswick Reservoir, and how this mixing is influenced by different operational parame

This digital dataset contains the surface water data used for both the Salinas Valley Watershed Model (SVWM) and the Lower Salinas Valley Hydrologic Models (Salinas Valley Integrated Hydrologic Model (SVIHM) and Salinas Valley Operational Model (SVOM)). The surface water dataset includes describes two regions of the Salinas River Watershed; the upper region is occurs primarily within San Luis Obis

The Lower Salinas Valley Hydrologic Models’ discretization data includes a shapefile of the model domain and layers and a shapefile of the water balance subregions. The Lower Salinas Valley Hydrologic Models include a historical model, the Salinas Valley Integrated Hydrologic Model (SVIHM) and a reservoir operations model, the Salinas Valley Operational Model (SVOM). While the Lower Salinas Valley

This dataset is a compilation of Longfin Smelt observations from multiple sources, including research institutions and museums, and local, state, and federal fisheries agencies.

This digital dataset includes three sets of observational data (groundwater level, streamflow, subsidence) used to calibrate the updated Central Valley Hydrologic Model (CVHM2)

This digital dataset contains datasets used to develop the Subsidence Package in CVHM2. Data includes number of delay interbeds per model cell (Neq), equivalent thickness for a delay interbeds (Beq), and the zones used to define subsidence parameters. Beq and Neq are calculated from the database of well logs, which is provided in the parent dataset. Five zones are used to define subsidence paramet

This digital dataset contains datasets used to develop the Multi Node Well (MNW2) Package in CVHM2. It includes well locations, well properties for Municipal Pumping, Rural Pumping, Recovery Pumping, and Agricultural Pumping. The data release also includes pumping rates for Municipal Pumping, Rural Pumping, Recovery Pumping. Agricultural Pumping are estimated in CVHM2 by the farm process, and thus

This digital dataset contains historical geochemical and other information for 89 samples of produced water from 84 sites in the Santa Maria Valley Oil Field in Santa Barbara County, California. Produced water is a term used in the oil industry to describe water that is produced from oil wells as a byproduct along with the oil and gas. Additionally, 3 samples from 3 sites that represent source wat

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.

This digital dataset contains the monthly inflows and diversions to the surface-water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The surface-water network simulates the Central Valley’s complex conveyance network through the Streamflow Routing Package (SFR2) and the Farm-Process (FMP4) at 65 inflow locations with 271 stream segments and 13 bifurcation
