Data

This U.S. Geological Survey (USGS) Data Release provides selected discretely measured water-quality data collected from 27 monitoring sites in Johnson County, Kansas, during January 2015 through November 2018. Water-quality samples were analyzed for nutrients, Escherichia coli bacteria, total suspended solids, suspended-sediment concentration, and chlorophyll as part of a study to assess...

The purpose of this data release is to provide the original data, analysis methods, and nitrogen loading models in support of a study of the upper South Platte River annual total nitrogen loads attributed to atmospheric deposition of reactive nitrogen during 2017-2018. The data release includes water-quality and stream discharge data and associated predictive regression models used in...

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project. One of the major goals of the NAWQA project was to determine how river water quality has changed over time. To support that goal, long-term consistent and comparable monitoring has been conducted by the USGS on...

Data were collected at 60 surface water and two effluent sites across Iowa in 2019-2020 by staff from the U.S. Geological Survey Central Midwest Water Science Center. Samples were submitted to the National Water Quality Laboratory in Denver, Colorado, and were analyzed for per- and polyfluoroalkyl substances.

Note: This data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P9HGC2V4 During review of the parent report for this data release, Walton-Day and others (2021), an error was discovered in the reported bromide injectate concentration. In addition, rounded bromide concentrations reported in version 1 were not sufficient to allow a user to recalculate...

The Savannah Harbor Expansion Project (SHEP) began in January 2015 with the purpose of deepening the Savannah Harbor federal shipping channel to allow access to larger shipping vessels (U.S. Army Corps of Engineers, 2018a). There are various features and mitigation efforts to the SHEP, one of which is the installation of a dissolved-oxygen (DO) injection system at two locations along the...

This data release provides gradient self-potential (SP), conductivity, and temperature measurements made during an investigation of surface-water and groundwater exchange in Lake Travis near Austin, Texas, where the Colorado River is incised into two zones of the Cretaceous-age Trinity aquifer (the lower-zone, and several hydrostratigraphic units of the middle zone). The voltage...

The watershed data management (WDM) database SC18.WDM is updated with the processed data for the period October 1, 2018, through September 30, 2019. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around DuPage County, Illinois. Hourly precipitation and...

This data release is the update of the U.S. Geological Survey (USGS) - ScienceBase data release Bera (2020b), with the processed data for the period October 1, 2018, through September 30, 2019. This data release describes the watershed data management (WDM) database file WBDR19.WDM. The WDM database file WBDR18.WDM (Bera, 2020b) is updated with the quality-assured and quality-controlled...

This data release contains data used in an upcoming associated publication currently in review. The overarching effects and benefits of land management decisions, such as through watershed restoration, are often not fully understood due to a lacking control within an experimental design. This can be addressed through the application of a paired watershed approach, allowing for comparison...

WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including flood and droughts. Real-time information generally is updated on an hourly basis.

A three-level SWAN (version 41.31) nesting grid has been developed for the central Beaufort Sea coast to simulate waves over the hindcast period 1979 - 2019. The model includes the implementations of sea ice by Rogers (2019) and includes both 1) a dissipation source term and 2) a scaling of wind input source as functions by sea ice. The bathymetric dataset used for the model is the...
