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.

Direct Human-Impact Classifications for Selected Groundwater Wells in the Conterminous United States, model archive Direct Human-Impact Classifications for Selected Groundwater Wells in the Conterminous United States, model archive
This data release contains data used to develop and apply a model that estimates the level of direct human-impact on selected groundwater wells in the conterminous United States. An extreme gradient boosting model was developed to estimate the probability of minimal human-impact to water levels in groundwater wells. The model uses human-impact evaluations from regional groundwater...
Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater
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...
Data and analytical code associated with a modified Lotka-Volterra model, assessing population-level co-occurrence effects between barred (Strix varia) and northern spotted owls (Strix occidentalis caurina), in western Oregon (1990 – 2015) Data and analytical code associated with a modified Lotka-Volterra model, assessing population-level co-occurrence effects between barred (Strix varia) and northern spotted owls (Strix occidentalis caurina), in western Oregon (1990 – 2015)
This data release provides data from the 2016 Lesmeister et al. technical report and Mathematica and Python analytical code to model co-occurrence effects between barred (Strix varia) and northern spotted (Strix occidentalis caurina) owls. This data release, containing sample data set and code, is designed to facilitate reproducibility of analyses associated with the manuscript titled...
Surface Geophysical Data Collected at, and Adjacent to Hanscom Air Force Base, Bedford, Massachusetts, 2024 Surface Geophysical Data Collected at, and Adjacent to Hanscom Air Force Base, Bedford, Massachusetts, 2024
In 2024 the U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineer Center (AFCEC), conducted geophysical surveys at Hanscom Air Force Base, Hanscom Field, and surrounding areas in Massachusetts. Methods used included frequency-domain electromagnetic induction (EMI), ground-penetrating radar (GPR), horizontal-to-vertical spectral ratio (HVSR) passive seismic...
Water Quality Vertical Profile Data in West Thompson Lake, Connecticut, 2022 and 2024 Water Quality Vertical Profile Data in West Thompson Lake, Connecticut, 2022 and 2024
This data release consists of vertical water-quality profile data collected at three locations in West Thompson Lake Connecticut from June to October 2022 and from May to October 2024. The U.S. Geological Survey, in cooperation with the Connecticut Department of Energy and Environmental Protection, collected these data to assess physical property stratification in the West Thompson Lake...
Kīpahulu Valley, Haleakalā National Park, Maui bird, mosquito, and avian malaria infection data, 2002 and 2019 Kīpahulu Valley, Haleakalā National Park, Maui bird, mosquito, and avian malaria infection data, 2002 and 2019
This data publication contains data files collected as part of a field and laboratory effort aimed at estimating the prevalence and altitudinal distribution of avian malaria in forest birds and in the primary vector of malaria in Hawaii, Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, on the island of Maui in 2002 and 2019. To track the spread of mosquitoes and...

This data release contains (1) principal facts of gravity measurements by previous studies and collected by the U.S. Geological Survey in 2006-2024, (2) geophysical grids, and (3) horizontal gradient maxima derived from gravity and magnetic potential fields of the Healdsburg 30 by 60 minute quadrangle, California. Gridded data are provided in geotiff format. These data support modeling...
Rodent habitat and community data to evaluate outcomes of wildfire and post-fire restoration treatments Rodent habitat and community data to evaluate outcomes of wildfire and post-fire restoration treatments
This dataset contains observations used to better understand rodent habitat and community composition 2-15 years post-wildfire with different post-fire restoration treatments (post-fire seeding of native or non-native species). Field data come from 3 wildfire sites in the Northern Basin and Range Ecoregion. Vegetation structure and composition measurements were collected at 71 plots, and...
Riparian plant and ecosystem water use data in North American drylands between 1997 and 2020 extracted from published studies Riparian plant and ecosystem water use data in North American drylands between 1997 and 2020 extracted from published studies
These data were compiled to support a synthesis of over two decades of riparian plant and ecosystem water use estimates from the drylands of North America. The objectives of the study were to determine if some riparian plant communities exhibit lower plant water use than others, assess if plant water use changes under hotter climates, and evaluate if models based on existing data, plant...
Computed and estimated streamflow in Bronson and Fanno Creeks, OR, 2016-2017 Computed and estimated streamflow in Bronson and Fanno Creeks, OR, 2016-2017
The USGS computed streamflow during 2016 and 2017 at two sites – one on Bronson Creek (USGS station 453250122494501) and one on Fanno Creek (USGS station 452738122474100), which are tributaries to the Tualatin River in northwestern Oregon. The computed streamflows from the two aforementioned sites were then used to estimate the corresponding streamflow at two other sites- USGS station...
Underwater imagery and classifications of the substrate and coral reef habitat on the Kona coast of the Island of Hawai`i, from 2003, 2004, and 2022 Underwater imagery and classifications of the substrate and coral reef habitat on the Kona coast of the Island of Hawai`i, from 2003, 2004, and 2022
Images of the seafloor off the Kona coast of the Island of Hawai`i were collected by the United States Geological Survey in 2003, 2004, and 2022, during field activities A803HW, A204HW, A604HW, and 2022-615-FA. The images were acquired in cooperation with the National Park Service, primarily in the waters off Kaloko-Honokohau National Historical Park, Pu`ukohola Heiau National Historic...
