Data

The USGS Water Resources Mission Area provides water information that is fundamental to our economic well-being, protection of life and property, and effective management of our water resources. Listed below are discrete data releases and datasets produced during our science and research activities. To explore and interact with our data using online tools and products, view our web tools.

U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2017 - 2018

The USGS Precipitation Chemistry Quality Assurance Project (PCQA) operates QA programs to challenge and test the National Atmospheric Deposition Program (NADP) data-collection processes for both the National Trends Network (NTN) and Mercury Deposition Network (MDN). PCQA data are available in separate tables for each quality-assurance program: (1) NTN Interlaboratory-comparison, (2) MDN Interlabor

Dataset used for estimating catchment-level nitrogen and phosphorus fertilizer use from commercial fertilizer sales data for the Conterminous U.S., 2012

This dataset includes all of the variables that were used in predictive models to estimate nitrogen and phosphorus fertilizer use from commercial fertilizer sales data at the catchment/county level for the Conterminous U.S. for the year 2012. The dataset includes model input at the catchment/county level. A companion USGS Scientific Investigations Report describes the methods and subsequent result

Field measurements of flow velocity and optical image sequences acquired from the Salcha and Tanana Rivers in Alaska in 2018 and 2019 and used for particle image velocimetry (PIV)

This data release includes field measurements of flow velocity and optical image sequences used to derive remotely sensed estimates of surface flow velocities via particle image velocimetry (PIV) from two rivers in Alaska. These data were acquired from the Salcha River on August 31, 2018, and the Tanana River on July 24, 2019. The purpose of this study was to assess the feasibility of inferring

Permafrost Mapping in Two Wetland Systems North of the Tanana River in Interior Alaska 2014

Surface-based 2D electrical resistivity tomography (ERT) surveys were used to investigate the distribution of permafrost at wetland sites on the alluvial plain north of the Tanana River, 20 km southwest of Fairbanks, Alaska, in June and September 2014. The sites contained habitat types characteristic of interior Alaska, including thermokarst bog, forested permafrost plateau, and a rich fen. These

Biogeochemical Data for Mercury and other Constituents in Surface Sediment and Deep Cores from the Hells Canyon Reservoir Complex, Idaho and Oregon 2014-2018

The Hells Canyon Complex (HCC) is comprised of a series of three consecutive reservoirs (Brownlee, Oxbow, and Hells Canyon) along a 145 km reach of the Snake River bordered by Idaho to the east and Oregon to the west. Due to concerns regarding mercury (Hg) contamination within the HCC, in cooperation with Idaho Power Company, the U.S. Geological Survey has been leading an investigation into the so

Green-Ampt infiltration modeling following wildfire in the Colorado Front Range, USA

This product is a Model Archive for Green-Ampt method infiltration modeling following wildfire in the Boulder Creek watershed, in the Colorado Front Range, USA. The models contained in this archive simulate infiltration and consequent runoff generation through 7 years of recovery following a wildfire in 2010. These simulations provide insight to changes in the timing of runoff generation that have

Lotic vs. Lentic Water: a U.S. national 30-meter raster classification of water areas by velocity

This dataset consists of a national 30-meter raster which classifies pixels representing water from the National Land Cover Database 2016 (NLCD 2016) according to their estimated velocity regime. At the broadest classification, the data are mapped into two groups: "Lentic", representing water bodies such as lakes, ponds, oceans, and bays, and "Lotic", representing flowing water, such as streams, r

MODFLOW-2005 model used to Simulate the Evolution of Fluid Underpressures in the Great Plains, by Incorporation of Tectonic Uplift and Tilting

A sequence of nine groundwater models was created to study whether underpressures (subhydrostatic heads) in the Paleozoic units underlying the Great Plains of North America are a consequence of Cenozoic uplift of the area. Based on tectonostratigraphic data, we have incorporated into these nine models a cumulative uplift history with superimposed periods of deposition and erosion for the Great Pla

Data for the U.S. Geological Survey Precipitation Chemistry Quality Assurance Project for the National Atmospheric Deposition Program, 1978-2017

The U.S. Geological Survey has operated the Precipitation Chemistry Quality Assurance (PCQA) Project to evaluate and document the data quality for the National Atmospheric Deposition Program (NADP) for 40 years. The PCQA is primarily focused on data quality for the NADP National Trends Network (NTN) and Mercury Deposition Network (MDN). The PCQA implements programs to evaluate the variability and

Kentucky Drought Condition Monitor

The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme drought.

Sediment composition data from northern Pennsylvania

Sediment composition data to support the manuscript "Multivariate analysis of shale gas development on the chemical and biological health of headwater streams".

Selenium concentrations in tissues of the cyprinid Sacramento Splittail of the San Francisco Estuary (2010-11 and 2017)

Estuaries provide critical habitat for a vast array of fish and wildlife but are also a nexus for core economic activities that mobilize and concentrate contaminants that can threaten aquatic species. Selenium (Se), an essential element and potent reproductive toxin, is enriched in parts of the San Francisco Estuary (SFE) to levels known to cause toxicity, yet the risk of Se to species that inhabi
