Post-wildfire rain gage data for Fourmile Canyon, Colorado and Rendija Canyon, New Mexico

Rain-gages are critical instrumentation for documenting the rainfall forcing of post-wildfire hydrologic, erosional, and water-quality response. This USGS Data Release presents tipping-bucket rain gage data following two wildfires: the 2000 Cerro Grande Fire near Los Alamos, New Mexico and the 2010 Fourmile Canyon Fire near Boulder, Colorado. The data presented in this USGS Data Release are used f

Site visit cross section surveys and multispectral image data from gaging stations throughout the Willamette and Delaware River Basins from 2022 and code for Bathymetric Mapping using Gage Records and Image Databases (BaMGRID)

This data release includes cross section survey data collected during site visits to USGS gaging stations located throughout the Willamette and Delaware River Basins and multispectral images of these locations acquired as close in time as possible to the date of each site visit. In addition, MATLAB source code developed for the Bathymetric Mapping using Gage Records and Image Databases (BaMGRID) f

Modeled transport components of daily chlorophyll-a in the Illinois River, 2018 through 2020 (version 1.1, April 2024)

TThis data release contains approximately three years of modeled chlorophyll-a—a proxy for planktonic algal biomass—transport through a 394-km portion of the Illinois River. Defined by four distinct reaches, model estimates include daily water balance, velocities, and algal biomass separated into its components of net growth, net loss, transported from upstream, and input from tributaries.

Identifying structural priors in a hybrid differentiable model for stream water temperature modeling at 415 U.S. basin outlets, 2010-2016

This model archive (Rahmani et al. 2023a) provides all data, code, and model outputs used in Rahmani et al. (2023b) to improve model representations toward improved prediction of stream temperature and groundwater/subsurface flow contributions to stream temperature. Briefly, we modeled stream temperature at sites across the continental United States using a hybrid differentiable model that combine

Database of post-wildfire floods and debris flows

This database contains information on peak flows (floods, hyperconcentrated flows, and debris flows) after wildfire. Data were collected from the scientific literature and the U.S. Geological Survey National Water Information System. These data provide a foundation to assess the upper limits of post-wildfire floods that imperil human lives, infrastructure, and water supplies. Literature citations

Long-term water-quality trends for rivers and streams within the contiguous United States using Weighted Regressions on Time, Discharge, and Season (WRTDS)

The U.S. Geological Survey (USGS) Water Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand. It is also improving understanding of the natural and human factors affecting the balance between supply and demand. A key part of these

Twelve-digit hydrologic unit soil moisture, recharge, actual evapotranspiration, and snowpack water equivalent storage from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System 1980-2016

This dataset is part of the National Water Census Water Budget Estimation and Evaluation Project's ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of actual evapotranspiration and snowpack water equivalent storage are added to the already released estimates of soil moisture, recharge, str

Measurements of Water Quality Constituents in Groundwater Within 1 Mile (1.61 km) of Orphaned Wells in the United States

This is a combined dataset from the USGS Orphaned Well Dataset (Grove and Merrill, 2022) and publicly available data from the USGS National Water Information System, NWIS, obtained via the Water Quality Portal using the USGS Python dataretrieval library. This dataset is composed of water quality measurements from groundwater sites located within 1 mile of the locations of unplugged orphaned wells

Metal concentrations in streambed sediment in the lower Klamath River basin, 2018-2022

The U.S. Geological Survey is monitoring metal concentrations in streambed sediment pre- and post-dam removal in the lower Klamath River basin. Concentrations of aluminum, arsenic, cadmium, cobalt, chromium, copper, iron, potassium, magnesium, manganese, nickel, lead, titanium, vanadium and zinc were sampled at 10 mainstem sites, four tributaries and two reservoirs.

Helicopter-based videos and orthomosaic maps produced for Integrated Water Science basin riverine study sites, 2022

A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Integrated Water Science basin riverine study sites in 2022. Videos were collected using both natural color and thermal infrared cameras. These videos were used to determine the feasibility of estimating river surface velocity using aerial imagery. Orthomosaic maps were produced from the natural color videos u
