Data

The glacial deposits underlying southeastern Michigan, northeastern Indiana, and northwestern Ohio are a substantial source of water to communities, agriculture, and industry in the region. The U.S. Geological Survey, in cooperation with the Ohio Environmental Protection Agency, used processed data from the State-managed collections of well records to develop a hydrogeologic framework of...

This release presents data from surveys of physical and hydrologic characteristics of the Ohio River streambed and adjacent alluvial aquifer and other related information to document conditions and changes relative to water withdrawals from a series of horizontal, radial collector wells in a riverbank filtration system near Louisville, Kentucky. Surveys were completed by the U.S...

This data release archives files associated with a Kentucky flood-frequency analysis using annual peak-flow data through water year 2021 (a water year is defined as the period from October 1 through September 30 and is designated by the calendar year in which it ends). The analysis was completed using PeakFQ (version 8.1.0; Siefken and others, 2024; for full citation see the attached...

This Open Geospatial Consortium (OGC) GeoPackage (.gpkg) contains water-well point features and associated tables for the state of Louisiana, reformatted according to a U.S. Geological Survey (USGS) profile of the OGC GroundWaterML2 (GWML2) standard (https://docs.ogc.org/is/19-013/19-013.html). The water-well records are sourced from the state-managed database of the Louisiana Department...

Data include total nitrogen and organic carbon, total metal, and particle-size analyses of upland (cropland, woodland, gullies, roads) and streambank from the East River basin, Brown County, Wisconsin that was collected in July and August 2022. These data will be used in a sediment-source apportionment tool to attribute the proportional contribution of individual sources to suspended...

Data include particle-size distribution as well as sediment-bound total concentrations of carbon (organic and total), nitrogen, phosphorus, and other trace metals. Samples include those from upland sources (cropland, woodland, gullies, roads) as well as exposed streambank from the East River basin, Brown County, Wisconsin. Sources samples were collected in July and August 2022. These...

Digital flood-inundation maps for a 2.7-mile reach of Rio Grande De Loiza in and near Caguas, Puerto Rico, were created by the U.S. Geological Survey (USGS) with funding from the U.S. Geological Survey Supplemental Oversight Team which received funding for this effort through Title VII of Division N in the Consolidated Appropriations Act, 2023 (Public Law 117–328). Flood profiles were...

The Maumee River network contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved P, to the Western Lake Erie Basin. Most Maumee River headwater streams are agricultural, with conservation management focused on limiting sediment and nutrient transport from cropland to the stream network. However, several studies have shown streambank...

This data release includes physical and chemical data for streambed-sediment samples collected at 7 locations in the Little Flatrock Creek basin in Paulding County, Ohio during July 2019. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 41 metals, and particle-size analysis; not all samples had enough for all analyses. Source samples were...

These data are comprised of beryllium-7 (7Be) and excess lead-210 (210Pbxs) activity for fine-grained, mobile, streambed sediment at seven reaches in the Little Flatrock Creek stream-channel network. This basin is monitored in cooperation with the Ohio Department of Natural Resources. During the period July 26-27, 2019 (summer low flow), the thickness and spatial extent of soft, mobile...

Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed sediment from Little Flatrock Creek, Paulding County, Ohio. These data will be used in a sediment-source mixing model to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were identified as one of four land-cover...
