This data release contains key variables from the Weather Research and Forecasting Hydrological Modeling (WRF-Hydro) application forced with the CONUS404 climate forcing variable subset for hydrologic models that was downscaled to one-kilometer and bias-adjusted for precipitation and temperature (CONUS404BA) from water year 2010 through water year 2021 that are summarized to a monthly...

Clear Lake is a 180 km2 freshwater lake located approximately 120 km northwest of Sacramento in the California Coast Range. The lake is a popular sport-fishing destination, however, there are fish consumption advisories associated with mercury (Hg) contamination for several species. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower...

This model archive contains data and code used to assess the use of process-informed multi-task deep learning models for predicting in-stream dissolved oxygen concentrations. Three holdout experiments were run to assess model performance, including a temporal holdout experiment, a spatial holdout experiment with similar sites held out, and a spatial holdout experiment with dissimilar...

A series of field measurements of surface water velocity derived from video and Doppler velocity radar collected by small unoccupied aircraft systems (sUAS) and portable sensors were collected at seven locations in Colorado, USA, during the summer of 2023. The measurements were utilized to compute surface velocity and discharge using the Probability Concept, Large-Scale Particle Image...

This dataset contains the initial 3D Hydrography Program (3DHP) flow network topology, which is based on the final High Resolution National Hydrography Dataset (NHD), and a set of mainstem river identifiers based on the Medium resolution NHDPlus Version 2 (NHDPlusV2). The 3DHP flow network topology and mainstem identifiers contained in this data release add two key pieces of information...

Information on water depth in river channels is important for a number of applications in water resource management but can be difficult to obtain via conventional field methods, particularly over large spatial extents and with the kind of frequency and regularity required to support monitoring programs. Remote sensing methods could provide a viable alternative means of mapping river...

This data release contains fractional intersectional weights used to crosswalk data from the National Water Use Program to the National Integrated Water Availability Assessment (IWAAs) projects. The Watershed Boundary Dataset (WBD; https://www.usgs.gov/national-hydrography/watershed-boundary-dataset) is a companion dataset to the National Hydrography Dataset and contains polygons that...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts conducted from July to August 2019. An exposure experiment was conducted at an a PFAS contaminated site (FTA-1) near the fire training area (FTA). To assess the...

Per- and polyfluoroalkyl substances (PFAS) and co-occurring inorganic and organic contaminants are widely distributed in the environment and understanding their surface water sources is critical for water resource management. In November 2021, 13 sites were sampled along a stream reach in the Neshaminy Creek basin in southeastern Pennsylvania utilizing a time of travel sampling approach...

We conducted a scoping review to assess the current state of the science and knowledge gaps of post-wildfire water quality. A scoping review is a rapid, systematic approach that is more superficial compared to traditional reviews, and can be considered a preliminary study that informs future in-depth reviews, meta-analyses, or modelling efforts (Robinne et al., 2020). We developed a...

The USGS National Field Manual (NFM) states "A representative sample is one that typifies in time and space that part of the aqueous system to be studied" and "obtaining representative samples is of primary importance for a relevant description of the environment." The NFM contains detailed chapters on the best practices for representative and contamination free sampling of major and...
