The U.S. Geological Survey collected groundwater samples from 67 wells and 1 spring used for domestic and small system drinking water supplies in Placer, El Dorado, Amador, and Calaveras Counties, California in 2016-2017. The sites were sampled for the Mokelumne, Cosumnes, and American River Watersheds (MCAW) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Domestic and small-system wells commonly are screened at shallower depths than public-supply wells. The MCAW study unit covered the...

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 bifurcations, and 571 diversion locations providing 564 of semi-routed diversions and 7 non-routed diversions. The semi-routed deliveries are routed through the simulated surface-water network, while the non-routed delivery is simulated through linkages between the SFR2 and FMP4 packages in MODFLOW-OWHM. Surface water data for CVHM2...
The U.S. Geological Survey collected groundwater samples from 67 domestic wells and 1 spring used for domestic supply in Placer, El Dorado, Amador, and Calaveras Counties, California in 2016-2017. The sites were sampled for the Mokelumne, Cosumnes, and American River Watersheds (MCAW) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic drinking water supply. The MCAW study unit covered the parts of the Upper Mokelumne, Upper Cosumnes, and South and North Fork American River watersheds [8-digit hydrologic unit codes (HUC8) 18040012,...

Data in this document record the ground-surface positions from 1996 to 2018 of monuments located on different kinematic elements of the Cleveland Corral landslide, or on nearby more stable ground. Data were collected about once a year in campaign mode, at times when the landslide was dormant and not moving (typically late spring or fall). Survey timing was selected to identify wet-season movement of the slide, which typically occurs during the winter and spring. Between 1996 and 2000, positional information was collected by surveying pins (with rod and prism) from a total station instrument located across the valley from the landslide. Between June 2000 and March 2004, no surveys were performed. Starting in 2004,...

This data release codifies and attributes explanatory factors that could potentially impact groundwater quality at 142 groundwater sites (wells or developed springs) used for domestic water supply and 310 groundwater sites used for public water supply in the northern Sierra Nevada foothills. Water quality from domestic groundwater sites was assessed as part of the California State Water Resources Control Board’s Groundwater Ambient Monitoring and Assessment (GAMA) program in 2015-2017. Domestic groundwater sites from two of the U.S. Geological Survey’s Priority Basin Project Shallow Aquifer Assessment study units are attributed here: The Yuba-Bear Watersheds (YBW) study unit (sampled in 2015-2016) and the American-Cosumnes-Mokelumne...
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...
