Water-quality and streamflow datasets used in Seasonal Kendall trend tests for the Nation’s rivers and streams, 1972-2012 (output)

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 of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitor

Snake River above Jackson Lake at Flagg Ranch, WY (YSNA)

Snake River above Jackson Lake at Flagg Ranch, WY (YSNA) Sample Collection: Samples were collected near the USGS stream gage 13010065 (Latitude 44°05'56", Longitude 110°40'03" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were retained for chemical analyse

MODFLOW-2000 model used to evaluate potential effects of existing and proposed groundwater withdrawals on water levels and natural groundwater discharge in Snake Valley and surrounding areas, Utah and Nevada

A previously developed three-dimensional steady-state numerical groundwater-flow model was modified to
transient conditions with respect to well withdrawals, and used to simulate drawdown and capture of natural
discharge from existing and proposed groundwater withdrawals in Snake Valley and adjacent areas in
western Utah and eastern Nevada. The original steady-state model...

Combined remote sensing and water-balance evapotranspiration estimates (SSEBop-WB) for the conterminous United States

This dataset includes 1km resolution monthly timescale estimates of evapotranspiration (ET) for the 2000-2015 timespan. These new SSEBop-WB estimates were developed by combining a previously published long-term annual average evapotranspiration map based on water balance constraints with the SSEBop remote sensing ET product (see Associated Items). The combination aims to leverage the adva

GSFLOW groundwater-surface-water model 2016 update for the Trout Lake Watershed

A 2016 update was made to the GSFLOW model documented in SIR 2013-5159, which is
available online ( https://pubs.usgs.gov/sir/2013/5159/ ). The original GSFLOW model was
created to simulate climate changes effects on streamflow, lake budgets, and stream
temperature in the Trout Lake Watershed, Wisconsin. The computer code...

Isotopic and chemical composition (δ13C, Δ14C, δ15N, C:N, SUVA254nm, % HPOA) of aquatic carbon and field conditions (water temperature, pH, discharge) in the Upper Mississippi River Basin, October 2014 – February 2016

This dataset contains stable isotope (δ13C) and radioisotope (Δ14C) compositions of dissolved inorganic carbon, dissolved organic carbon, particulate organic carbon, and bed material organic carbon samples collected from rivers in the Upper Mississippi River Basin between October 2014 and February 2016. Rivers were sampled at USGS gaging stations: Minnesota River at Fort...

MODFLOW-LGR data sets for the Great Basin carbonate and alluvial aquifer system model version 3.0: Revisions in southwestern Utah and east central Nevada

A new version of previously published steady-state numerical groundwater flow models of the Great Basin
carbonate and alluvial aquifer system (GBCAAS), and was developed in conjunction with U.S. Geological
Survey (USGS) studies in Parowan, Pine, and Wah Wah Valleys, Utah. This version of the model is
considered to be GBCAAS v. 3.0 and supersedes previous versions. This mo

Data Sets for the Report Entitled, "A Field Study of Selected U.S. Geological Survey Analytical Methods for Measuring Pesticides in Filtered Stream Water, June-September 2012"

The National Water-Quality Assessment (NAWQA) Program and National Stream Quality Accounting Network (NASQAN) are U.S. Geological Survey (USGS) monitoring programs that measure pesticide concentrations in the Nation’s streams and rivers, herein collectively referred to as streams. The NAWQA Program began monitoring pesticides in 1992 and the NASQAN Program began monitoring p
