This data release documents socioeconomic and water demand indicators for the Mekong River delta region. The Mekong River provides many valuable benefits to the 60 million Southeast Asian residents living in its Basin. Maintaining adequate supplies of water in the Mekong River Basin is vital for food security. However, the Mekong River Basin is increasingly stressed by infrastructure development,

Phosphorus, nitrogen, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were calculated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2020 (USGS water years 2011–2020). Total phosphorus, orthophosphate, particulate phosphorus, total nitrogen, nitrate plus nitrite, ammonium p

This is a conversion of Wentworth and others (2023)[DAS1] to the Geologic Map Schema (GeMS) for inclusion in the National Geologic Map Database. The original publication was in the Alacarte schema commonly used for geologic map databases prior to the release of the now mandatory GeMS. The GIS layers in this release have the same scientific content as the source data release. The source data releas

The U.S. Geological Survey (USGS), in cooperation with the City of South Padre Island, Texas, deployed an acoustic Doppler current profiler (ADCP) to collect current velocity, wave height, and directional data in the lower Laguna Madre adjacent to South Padre Island, Texas. From July 19, 2022, through January 9, 2023, these data were collected at a site near South Padre Island (USGS station number

This dataset contains the concentration and quality assurance results for 34 per- and polyfluoroalkyl substances (PFAS). 409 residential and commercial tapwater samples were collected once between May 2021 and May 2022, in the contiguous U.S., Alaska, Hawaii, Puerto Rico, and U.S. Virgin Islands. Of these samples 252 were from publicly supplied tapwater locations, and 155 were sourced from private

This data release contains historical SnowModel (Liston and Elder, 2006) output for the Crown of the Continent and surrounding areas in Montana and Idaho, USA; and Alberta and British Columbia, Canada from September 1, 1981 through August 31, 2020. Fifteen daily variables were simulated or derived for this release: (1) snow water equivalent (swed), (2) liquid precipitation (rpre), (3) solid precip

Abandoned railroads and infrastructure from the anthracite coal mining industry are significant features in abandoned mine lands and are an important part of history; however, these features are often lost and masked by the passage of time and the regrowth of forests. The application of modern light detection and ranging (lidar) topographic analysis, combined with ground-truthing "boots on the gro

A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. These shapefiles contain the boundar

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting

The barrier islands and coastal beaches along the Atlantic Coast are dynamic systems continuously affected and shaped by tides and weather events (Davidson-Arnott 2010). Occasionally weather events are large enough to generate or expand beach overwash areas and may inundate all or part of the islands. Nor'easters, are known to play a significant role in shaping beach morphology along the Mid-Atlan

A wastewater reuse model was applied to the Upper Colorado River basin to assess the percent of accumulated wastewater (ACCWW%) from municipal and industrial wastewater treatment plants (WWTPs) in each initialized (that is, has an assigned hydrosequence number for flow-routing) National Hydrography Dataset Version 2.1 (NHDPlus V2.1) stream segment. Model inputs included (1) NHDPlus V2.1 stream geo

Recent declines in Lake Whitefish population abundance has prompted research to identify underlying mechanisms controlling survival of early life stages in the Great Lakes. In Lake Erie, the recruitment bottleneck window determining year class strength of Lake Whitefish occurs during the first growing season, suggesting that availability of prey could be controlling year class strength. Therefore,
