Data

The U.S. Geological Survey (USGS), in cooperation with the Louisiana Department of Transportation, prepared hydrologically-conditioned geographic information systems (GIS) layers for use in the Louisiana StreamStats application. This data release contains vector and raster geospatial data used to delineate drainage basins and raster geospatial data for precipitation data used to...

This U.S. Geological Survey data release consists of vector and raster geospatial datasets used to determine the volume of sediment in Pahranagat Wash, impounded above Arrow Canyon Dam, in northern Moapa Valley, Nevada. The data release includes: 1) a raster dataset of a 1-meter resolution digital elevation model (DEM) of the study area created using a lidar (light detection and ranging)...

Geologic map geodatabase depicting the surficial geology of the central Brooks Range, Alaska. Including the 250k quadrangles of Ambler River, Bettles, Chandalar, Chandler Lake, Hughes, Howard Pass, Killik River, Phillip Smith Mountains, Survey Pass, and Wiseman. Database tables include geologic linework and geologic units.

Salt marshes provide a range of ecosystem services, including storm protection, recreation, and commercial fishery habitat provision. The National Park Service (NPS) aims to preserve and protect salt marshes in order to achieve multiple objectives which address their mission: to preserve unimpaired the natural and cultural resources and values of their publicly held lands. Ongoing...

This dataset contains the well-location information and water-level measurements for 930 wells from 10 confined aquifers of the New Jersey Coastal Plain. Well-location and water-level data is publicly available from the U.S. Geological Survey (USGS) Water Data for the Nation database (USGS, 2025). Water-level measurements from 3 wells in Pennsylvania and reported water-level measurements...

This U.S. Geological Survey data release consists of multiple datasets used to simulate the streamflow extents and hydraulic characteristics of Meadow Valley Wash at Stuart Ranch near Rox, Nevada. Streamflow extents equal the maximum area of flow inundation and were estimated using a two-dimensional (2D) hydraulic model. The modeled extents represent baseflow and six annual exceedance

The data included here were used to evaluate the prospectivity for lithium in brines of playas of the western part of the Basin and Range Physiographic Province of the United States. Prospectivity is derived from the mappable criteria used in the descriptive deposit model published by Bradley and others (2013) and focused mainly from the remote sensing point of view. The playas in the...

The Edwards and Trinity aquifers are major sources of water for agriculture, industry, and urban and rural communities in south-central Texas. Both the Edwards and Trinity aquifers are classified as major aquifers by the State of Texas. The dissolution of the carbonate rocks composing the Edwards and Trinity aquifers results in distinctive landforms rich in both springs and karst...

This data release contains shapefiles and raster data of spatially distributed water level inundation, water depth, wave discharge and a set of hazard ranks for water levels, waves, and a combination of both for coastal areas of Long Island, NY and Long Island Sound. Water inundation and depth data include both current and future projections of inundation based on 4 annual exceedance...

The city of Sioux Falls, in southeastern South Dakota, is the largest city in South Dakota. The U.S. Geological Survey (USGS), in cooperation with the city of Sioux Falls, completed a groundwater-flow model to use for improving the understanding of groundwater-flow processes, estimating hydrogeologic properties, and analyzing groundwater and surface-water interactions for the Big Sioux...

This data release contains raster datasets representing depth to water table, calculated from steady-state groundwater models developed by the U.S. Geological Survey (Jahn and others, 2024; Barclay and others, 2024). The depth to water table rasters are available at an approximate resolution of 10 meters. In addition, depth to water table, hydrologic soil types, and landcover are...

This data release provides spatial digital data for factors that influence pluvial flood hazard potential, including closed depressions, curve number, drainage networks, topographic slope, average annual rainfall, 1-hr and 24-hour 100-year return period rainfall accumulation, and locations of recorded floods. In addition, these flood influencing factors are summarized to a common 900...
