The U.S. Geological Survey collected samples from 50 public supply wells during two distinct sampling episodes (2004-2005 and 2014) on the North-Central California coast. During each sampling episode, the samples were analyzed for 160 water-quality constituents, including water-quality indicators, nutrients, major and minor ions, trace elements, volatile organic compounds, and pesticide compounds. The paired-sample results were submitted to an evaluation method to determine whether or not step trends had occurred in the concentrations of each constituent. Quality-control samples were collected at a subset of the wells. The datasets presented here consist of a list and description of the 160 constituents, an Excel...

This digital dataset contains the monthly inflows to the surface water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The surface water inflows are simulated through the Streamflow Routing Package (SFR2) using 65 inflows locations, 271 stream segments that represent 4043 stream reaches, and 13 bifurcations that comprise the stream network. The bifurcations simulate the bypass canals that are used for flood control by routing water between two stream reach locations within the stream network. This dataset includes the inflow and bifurcation locations, monthly magnitude, and shapefiles of the gridded and non-gridded stream network.
This digital dataset contains the monthly diversions from the surface water network in the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The volume of water transported by surface-water diversions were updated in the CVHM2 from several sources, including: • The C2VSIM developed by DWR, • The WestSIM model, • Delta Mendota Canal turnout delivery data obtained from SLDMWA, • Delta delivery data obtained from Montgomery Watson. The surface water diversions are simulated through the Streamflow Routing Package (SFR2) using 571 diversion locations providing 564 semi-routed and 7 non-routed diversions. Linkages between SFR2 and the Farm-Process (FMP4) simulate the semi-routed and non-routed...
