Concentration results for inorganic constituents in discrete tapwater samples, Montana, 2024. Concentration results for inorganic constituents in discrete tapwater samples, Montana, 2024.
This data release provides the concentration and quality-assurance results for inorganic constituents analyzed in water-quality samples from 26 residential and commercial tapwater locations in Montana by the U.S. Geological Survey (USGS) Environmental Health Program (EHP), Tapwater Exposure Study. The samples were collected between June 10-12, 2024, from both public supply (8) and...
MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023 MidFish: A Large-Scale Aggregation of State Fisheries Data from the Midwestern United States from 1940 - 2023
Lakes in the Midwestern United States support valuable recreational, subsistence, and tribal fisheries. Fisheries assessments that support management decisions are typically conducted within political boundaries and at intervals that limit their spatial and temporal scope. Data aggregation across lakes and regions facilitates research extending across ecological gradients and...
Target chemical concentrations of mixed-organic compounds and microbiological indicators in tapwater, Montana, 2024 Target chemical concentrations of mixed-organic compounds and microbiological indicators in tapwater, Montana, 2024
This data release reports the concentration results for organic compounds (disinfection byproducts [DBP], pesticides, per- and polyfluoroalkyl substances [PFAS], pharmaceuticals and volatile organic compounds [VOC]), cyanotoxins, microbiological indicators, as well as radon-222 analyzed in samples collected from private well and public supply sourced tapwater samples from a community in...
Airborne magnetic and radiometric survey, Hartville Uplift and Shirley Mountains regions, Wyoming, 2025 Airborne magnetic and radiometric survey, Hartville Uplift and Shirley Mountains regions, Wyoming, 2025
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Hartville Uplift and Shirley Mountains regions of Wyoming. The survey is split into two blocks, one covering the Hartville Uplift region (Block A), and the other covering the Shirley Mountains region (Block B). The airborne survey was mainly funded by the State of...
Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) from River Morphology Characteristics in the United States Baseline Flow Resistance Parameters for Remote Sensing River Discharge (RSQ) from River Morphology Characteristics in the United States
This dataset contains discharge measurements derived from acoustic Doppler current profiler (ADCP) observations collected at U.S. Geological Survey (USGS) stream gage locations that are observable by the Surface Water and Ocean Topography (SWOT) satellite. ADCP measurements were compiled for the period 2015 through December 1, 2025 and paired with reach-scale median SWOT-observed water...
