Data Releases

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Microbial Communities Across a Successional Gradient at Indiana Dunes National Park, 2015-2017

This soil and vegetation data were collected along a successional gradient at the Indiana Dunes National Park. Soil samples were processed for standard soil chemistry, texture, and nutrients. DNA extracted from soil samples were analyzed for bacterial communities using 16S rRNA amplicon sequencing technique to understand the composition and distribution of these communities along the successional

Data and R Code to Derive Estimates of Groundwater Levels Using MOVE.1 Regression and Compute Monthly Percentiles for Select Wells in Massachusetts

This data release contains extended estimates of daily groundwater levels and monthly percentiles at 27 short-term monitoring wells in Massachusetts. The Maintenance of Variance Extension Type 1 (MOVE.1) regression method was used to extend short-term groundwater levels at wells with less than 10 years of continuous data. This method uses groundwater level data from a correlated long-term monitori

Conceptual headwater stream daily heat budget scenarios under varied shading and groundwater influence

The Neversink River watershed (above the Neversink Reservoir) in the Catskill Mountains of New York, USA has been a focus of U.S. Geological Survey research for decades regarding stream geochemistry, acidification, and ecology dynamics. In 2019, the Water Mission Area Next Generation Water Observing Systems Program (NGWOS) augmented the existing stream gage network to include multiscale instrument

Predicted Physical Habitat Metrics for the Chesapeake Bay watershed at the 1:100k scale, 2001-2019

Degraded physical habitat is a common stressor affecting river ecosystems and a primary focus of management activities, including stream restorations. In order to assess regional conditions and help prioritize management efforts, there is an ongoing need to provide estimates of different aspects of instream physical habitat conditions at spatially continuous scales. We utilized over 16,000 unique

MODFLOW-NWT model used for the simulation of groundwater flow and analysis of groundwater availability in the Boone and Roubidoux aquifers in northeastern Oklahoma, 1980-2017

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Boone and Roubidoux aquifers in northeastern Oklahoma by using MODFLOW-NWT (version 1.1.4) with the Newton formulation solver to simulate groundwater flow and account for the drying and rewetting of cells within the groundwater-fl

Calibration data and model archive summaries for suspended-sediment, total nitrogen, and total phosphorus concentration surrogate models at USGS station 01575900, Chiques Creek near Marietta, Pennsylvania, 2021-2023

The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture Natural Resources Conservation Service (USDA NRCS) has collected discrete stream samples for analysis of suspended-sediment, total nitrogen, and total phosphorus at the real-time streamflow and water-quality monitoring (turbidity and nitrate) station 01575900, Chiques Creek Near Marietta, Pennsylvania. Data w

Model Archive Summary for Suspended-Sediment Concentration at station 11510700, Klamath River below John C. Boyle power plant, near Keno, OR, water years 2019-2023

This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute point location suspended sediment concentrations at USGS streamgage 11510700 for water years 2019-2023. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 and USGS techniques and methods, book

River stage and temperature dataset for 2021-2024 collected for U.S. Army Corps of Engineers downstream of the Kinzua Dam, Pennsylvania.

This dataset contains river stage (in meters and feet), water surface elevation (WSE), and temperature data collected at 3 focal areas of research included in the Sustainable Rivers Program (SRP) in the Allegheny River that were collected and processed in collaboration with US Army Corps of Engineers (USACE). This dataset is a combination of data collected by Hobo* U20L water level data loggers an

Thermal imagery acquired from an Uncrewed Aerial System (UAS) and hydroacoustic measurements of flow velocity collected along the Sacramento River, California, November, 2023

A reach of the Sacramento River near Glenn, California, was selected as a field site to test a sensor payload developed by the U.S. Geological Survey and the National Aeronautics and Space Administration for estimating surface flow velocities in rivers. The payload, called the River Observing System (RiOS), can be deployed from an uncrewed aircraft system (UAS). RiOS includes visible and thermal c

Estimated seasonal nitrogen and phosphorus loads in selected streams of the conterminous United States, 1999 - 2020

Estimated seasonal total nitrogen and total phosphorus loads during 1999 through 2020 in selected streams of the conterminous United States and water-quality and stream flow data used to generate those estimates are presented in this dataset. Loads were generated as part of the Integrated Water-Availability Assessment (IWAA) Program of the U.S. Geological Survey (www.usgs.gov/mission-areas/water-r

Detrital Zircon U-Pb data from selected Appalachian rivers and Outer Banks-area coastal sediments

U-Pb isotopic data from zircon grains from the sediment bedload of seven modern rivers: the Susquehanna, Potomac, Roanoke, James, Peedee, Tar, and Cape Fear, as well as from three samples taken from beaches in Albemarle and Pamlico Sounds (North Carolina), two Pleistocene core samples, and three samples on the ocean-facing foreshore of the Outer Banks barrier islands (North Carolina and Virginia).

Delaware River Basin Stream Salinity Machine Learning Models and Data

This model archive contains the input data, model code, and model outputs for machine learning models that predict daily non-tidal stream salinity (specific conductance) for a network of 459 modeled stream segments across the Delaware River Basin (DRB) from 1984-09-30 to 2021-12-31. There are a total of twelve models from combinations of two machine learning models (Random Forest and Recurrent Gra
