One of the largest hydraulic mines (1.6 km2) is located in California’s Sierra Nevada within the Humbug Creek watershed and Malakoff Diggins State Historic Park (MDSHP). MDSHP’s denuded and dissected landscape is composed of weathered Eocene auriferous sediments susceptible to chronic rill and gully erosion whereas block failures and debris flows occur in more cohesive terrain. This data release includes a 1992 digital surface model (DSM), 1992 orthophoto mosaic, masked orthophoto of the study area, 1992 ground cover classification, and 1992 pruned DSM with the vegetation bias removed. Stereo-photogrammetry was used to create a 1992 digital surface model (DSM) and orthophoto mosaic from archived 1992 aerial photographs....

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...

The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 miles north-northeast of Barstow, California, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle Basins) within the NTC boundaries. In these basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, managed aquifer recharge using recycled water (treated wastewater) has offset water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (for example, wastewater disposal practices, landscape irrigation, and (or) leaking pipes). As part of a research study...

This dataset contains velocity and flow log data collected in 2004 for two Yucaipa Valley Water District (YVWD) public-supply wells, YVWD 55 and YVWD 56. Data were collected using the tracer-pulse method described in Izbicki and others (1999), in which a pulse of a rhodamine dye tracer is injected to a known depth in the well and the travel time of the tracer to a detector on the surface is measured. Velocity and cumulative flow are calculated from the dye-arrival times using methods described by Izbicki and others (1999). Flow for well YVWD 55 was calculated using the pump within the screened interval, which captured flow from above and below the pump intake. Flow for well YVWD 56 was calculated using the pump...
The spatial extents of verified irrigated lands were compiled from various federal and state sources across the nation and combined into a single Geographic Information System (GIS) geodatabase for the purpose of model training and validation. In cooperation with U.S. Geological Survey (USGS), researchers at the University of Wisconsin (UW) generated a nation-wide map of irrigated lands using remote-sensing techniques that will be incorporated into future irrigation water-use models. The verified spatial data varies in scope, accuracy, and time period represented, but in general represents GIS coverages (polygons) of agricultural land irrigated for at least some period during 2002–17. Data from 14 states were provided...

Managed aquifer recharge is a water-management strategy used to meet water demands during dry periods, or periods of high-water demand, when surface-water supplies are low. One method of managed aquifer recharge uses aquifer systems as subsurface reservoirs or ‘water banks’ to effectively and economically store surface water when surplus is available, and then recover the recharged groundwater to meet water demands during droughts. During these water shortages, increased groundwater pumpage can be used to offset shortfalls in surface-water supplies. Thus, surface-water reservoirs and water banks can be used conjunctively to effectively coordinate the use of groundwater and surface water. Data were compiled for ten...

In 2013, the first of several Regional Stream Quality Assessments (RSQA) was done in the Midwest United States. The Midwest Stream Quality Assessment (MSQA) was a collaborative study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA), the USGS Columbia Environmental Research Center, and the U.S. Environmental Protection Agency (USEPA) National Rivers and Streams Assessment (NRSA). One of the objectives of the RSQA, and thus the MSQA, is to characterize the relationships between water-quality stressors and stream ecology and to determine the relative effects of these stressors on aquatic biota within the streams (U.S. Geological Survey, 2012). To meet this objective, a framework of fundamental...

Northeast SJV (NESJV), Southeast SJV (SESJV), Western SJV (WSJV), and Southern SJV (SSJV). These regions were primarily defined from the California Department of Water Resources SJV groundwater subbasins (CDWR, 2003); minor modifications were made to the CDWR defined subbasin boundaries to optimize separation of groundwater derived from the Sierra Nevada to the east and from the Coast Ranges to the west under predevelopment conditions. Each region was divided into equal-area grid cells, ranging from 280 km2 in the SESJV to 984 km2 in the SSJV, for a total of 88 cells. These cell sizes were the minimum sizes in each region for which 60% of the cells in the region would contain at least 1 well with full major ion...

The U.S. Geological Survey, in cooperation with the California Department of Water Resources (DWR), has constructed a new spatially distributed Precipitation-Runoff Modeling System (PRMS) for the Merced River Basin (Koczot and others, 2021), which is a tributary of the San Joaquin River in California. PRMS is a deterministic, distributed-parameter, physical-process-based modeling system developed to evaluate the response of streamflow and basin hydrology to various combinations of climate and land use (Markstrom and others, 2015). Although further refinement may be required to apply the Merced PRMS for official streamflow forecast operations, this application of PRMS is calibrated with intention to simulate (and...

High-resolution, terrestrial laser scanning, also known as ground-based lidar (light detection and ranging), was used to quantify the volume of mercury-contaminated sediment eroded from an outcrop of historical placer-mining debris at the confluence of the South Yuba River and Humbug Creek in the Sierra Nevada mountains, about 17 kilometers northeast of Grass Valley, California. The outcrop could not be mapped non-destructively or in sufficient detail by traditional surveying techniques. Terrestrial laser scanning was used to produce centimeter-scale, three-dimensional maps of the complex outcrop surface at the study site, which was approximately 70 meters long, 30 meters wide and 20 meters high. The outcrop surface...
