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.

In situ measurements of Rhodamine WT dye concentration and turbidity made during a tracer experiment on the Big Piney River near St. Robert, MO, on August 25-26, 2021 In situ measurements of Rhodamine WT dye concentration and turbidity made during a tracer experiment on the Big Piney River near St. Robert, MO, on August 25-26, 2021
This data release includes fluorometer measurements of Rhodamine WT dye concentration and turbidity acquired during a tracer experiment performed on the Big Piney River near St. Robert, Missouri on August 25 - 26, 2021. The primary goal of this experiment was to perform a conservative tracer injection to better understand transport and dispersion processes related to environmental DNA...
Hydrogeomorphic Units and Catena Linkages for the Upper Mississippi River System Hydrogeomorphic Units and Catena Linkages for the Upper Mississippi River System
In 2020 the U.S. Geological Survey (USGS), as part of the Upper Mississippi River Restoration (UMRR) Program, began a project to characterize potential hydrogeomorphic change associated with hydrogeomorphic units (HGUs) and their catenae (units linked by their association with sediment sources and flow origins). The objective of the project was to develop a geographic information system...
In-Situ Water Temperature Data Compiled from Multiple Agencies Across the Willamette River Basin, Oregon, 2011 to 2024 In-Situ Water Temperature Data Compiled from Multiple Agencies Across the Willamette River Basin, Oregon, 2011 to 2024
This data release contains a dataset of continuous in-situ water temperature records from multiple federal, state, local agencies, non-profit organizations, and private industry partners across 788 locations within the Willamette River Basin (WRB) from years 2011 to 2024. This dataset complements and extends the existing multi-agency NorWeST water temperature dataset for the Willamette...
Topographic point clouds and change analysis for the Big Sur, California coastline from structure-from-motion photogrammetry from aerial photographs, 2017-2023 Topographic point clouds and change analysis for the Big Sur, California coastline from structure-from-motion photogrammetry from aerial photographs, 2017-2023
This data release presents structure-from-motion (SfM) products derived from aerial imagery collected along the California coast as part of an ongoing effort by the USGS Coastal and Marine Hazards and Resources Program (CMHRP) Remote Sensing Coastal Change (RSCC) project. The products presented herein are point cloud and change detection products for 33 flights between January 2017 to...
Groundwater Drought Metrics for Selected Groundwater Wells in the conterminous U.S. from 1981-2020 and from 2001-2020 Groundwater Drought Metrics for Selected Groundwater Wells in the conterminous U.S. from 1981-2020 and from 2001-2020
This metadata record describes a series of datasets containing metrics used to characterize drought for groundwater wells in the conterminous United States (CONUS). This data is associated with a publication that looks to answer questions about groundwater drought in CONUS. The publication uses the time periods 1981-2020 and 2001-2020, but this dataset includes additional time periods...
Data from Decadal Change in Groundwater Quality Web Site, 1988-2024 Data from Decadal Change in Groundwater Quality Web Site, 1988-2024
Evaluating Decadal Changes in Groundwater Quality: Groundwater-quality data were collected from 5,000 wells between 1988-2001 (first decadal sampling event) by the National Water-Quality Assessment Project. Samples are collected in groups of 20-30 wells with similar characteristics called networks. About 1,500 of these wells in 67 networks were sampled again approximately 10 years later...
