Clear Lake, located in Lake County, California, is impacted by mercury contamination associated with the historic Sulfur Bank mercury mine, which is adjacent to the lake’s eastern shore / Oaks Arm region. As part of a larger study designed to better understand the biogeochemical cycling of mercury in Clear Lake, shallow sediment (top 0-2 cm or 0-4 cm) was sampled from the three major...

Dynamic Surface Water Extent (DSWE) annual proportions of total surface water processed to the continental US Analysis Ready Data (ARD) tile scheme (https://landsat.usgs.gov/ard_tile) in Sarbanes and Jones 2025 are here resampled to the 20 m Sentinel-2 satellite grid using bilinear interpolation with a 3 by 3 pixel moving window. The resulting 973 tiles, with values ranging from 0 to 100...

During August 2023, transient electromagnetic (TEM) surveys were carried out at select locations in Lake County near Leadville, Colorado upgradient from the Dinero tunnel bulkhead. TEM data were collected using an ABEM WalkTEM2 advanced instrument running acquisition software version 1.3.7.4 and using a single-turn transmitter loop (Tx) and a center-loop receiver (Rx). Tx loop dimensions...

During December 2022 and April 2023, the U.S. Geological Survey, in cooperation with U.S. Water Partnership, collected ground-penetrating radar (GPR) data in select small subwatersheds and arroyos within the Los Planes watershed south of La Paz in southern Baja California Sur, Mexico to map the depth to bedrock for use as inputs to a groundwater flow model. This data release contains the...

This Data Release contains four child items that represent sequential data processing and modeling steps. {Child Item 1} Data Preparation contains data inputs and processing steps for select sites in the Delaware and Illinois River Basins (DRB/IRB). This child item includes five sub folders: site info, streamflow and turbidity time-series, climatological information, basin shape...

This data release contains a registry and comparison of the representation of twelve-digit hydrologic unit code (HUC) hydrologic unit polygons from four snapshot versions of the Watershed Boundary Dataset (WBD). The four versions were chosen due to their pressence in broadly: National Hydrologic Dataset Plus V2.1 (nhdpv2) and National Hydrologic Dataset Plus High Resolution (nhdphr)...

These data files have information for hydrologic features contained in the Watershed Boundary Dataset (WBD) feature datasets. The datasets include information about the 12-digit HUC polygons for the USGS Regional Integrated Methods for Base Evaluation (RIMBE) of five Integrated Water Science (IWS) study areas: Delaware River Basin (DRB), Illinois River Basin (IRB), Trinity-San Jacinto...

This data release provides a Compilation of Images from River Reaches across the United States (CIRRUS). These images were retrieved programmatically using the Google Maps Application Programming Interface (API). The data set consists of a total of 281,024 individual images from rivers throughout the contiguous U.S. and Alaska, with an emphasis on locations likely to have rapids. For the...

Land applied waste byproducts were collected by USGS from 34 sites across the United States. Materials included waste byproducts from treatment of municipal sewage (biosolids), production of food (bovine, poultry, and swine wastes), and drilling of oil and gas wells (spent oil- and water-based drilling fluids). The samples represent 10 municipal wastewater treatment plants, 11 animal...

In the United States, the widespread use of pesticides has led to contamination of groundwater resources. Three decades ago, the U.S. Geological Survey (USGS) established a national water quality monitoring network for groundwater (NWQN-GW). This network provides an overview of groundwater conditions across a wide range of hydrogeologic settings and capture the impacts of pesticide use...

This data release provides R scripts for estimating future stream water quality using Weighted Discharge on Time Discharge and Season for Projection (WRTDS-P). The technique is tested against hold-out data and is applied to four drought scenarios in the Delaware River Basin (DRB). The scripts retrieve WRTDS models from an existing data release for 39 sites in the DRB with observations...

This data release contains input data used to test multi-scale modeling approaches for predicting water temperature in streams and rivers. The target application aims to predict stream temperature at relatively fine spatial resolution across a river basin by combining a machine learning (ML) model (optionally, with additional input data) configured at a relatively coarse spatial...
