Data and Tools

The USGS Water Resources Mission Area provides water information that is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. Below, find data and tools relevant to a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

Data on soil denitrification enzyme activity and characteristics of tidal freshwater forested wetlands in Virginia.

Denitrification measurements and ecosystem attributes in hummock-hollow microtopography of tidal freshwater forested wetlands along longitudinal riverine positions (upper, middle, and lower tidal river sites, and nearby upstream nontidal forested floodplains) of the adjoining Pamunkey and Mattaponi Rivers, Virginia.

Depth measurements from the upper Sacramento River in northern California, September 11-14, 2017

Field measurements of water depth were acquired from a reach of the upper Sacramento River in northern California, September 12-14, 2017, to support research on salmon habitat and geomorphic change along the Sacramento River and, more broadly, remote sensing of rivers. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS

MODFLOW-LGR2 groundwater-flow model used to delineate transient areas contributing recharge and zones of contribution to selected wells in southeastern Albuquerque, New Mexico

A three-dimensional groundwater-flow model of a 73.2 square mile area in southeastern Albuquerque,
New Mexico was designed and coupled to a regional (parent) model of the Middle Rio Grande Basin
with the local-grid refinement numerical code MODFLOW-LGR2. This fine-gridded local (child) model
was designed to simulate the response of the aquifer to pumping stresses and simulate...

A spatially explicit model of long-term mean annual streamflow for the conterminous United States

The data release documents the development of a hybrid
(statistical-mechanistic) SPARROW (SPAtially Referenced
Regression On Watershed attributes) model of long-term
mean annual streamflow applied to streams and rivers of
conterminous United States. The model coupled previous
catchment-scale (1-km) water balance predictions of “natural”

Geophysical data from the unnamed lake at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, MN

The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near Bemidji, MN, USA. A high pressure oil pipeline ruptured in 1979 releasing ~1.7 million liters of light crude oil, which sprayed over an area of ~6500 square meters and collected in topographic depressions. Approximately 75% of the spilled oil was recovered. Much of the remainder reached the water t

MODFLOW-2005 model and supplementary data used to characterize groundwater flow and effects of pumping in the Death Valley regional groundwater flow system, Nevada and California, with special reference to Devils Hole

A three-dimensional, groundwater model (MODFLOW-2005) was developed to determine
effects of future (2019–2100) groundwater development on water levels and natural discharges
in the Alkali Flat–Furnace Creek Ranch (AFFCR), Ash Meadows, Pahute Mesa–Oasis Valley
(PMOV), and Pahrump to Death Valley South (PDVS) groundwater basins, souther

Monthly timescale quick-flow runoff maps for the conterminous U.S., 1895-2017

This dataset includes 1km resolution monthly timescale estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 1895-2017. These estimates were developed with a regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1301 gaged watersheds as a function of surficia...

SUTRA model used to evaluate the freshwater flow system for a future (2080-2099) climate on Guam

A previously published three-dimensional, groundwater model (SUTRA)
(http://doi.org/10.3133/sir20135216) was used to evaluate the effects
of future climate and withdrawal on the freshwater lens of Guam. The
model was run using 2080 to 2099 estimated recharge and sea-level
rise. This USGS data release contains all of the...

Yukon-Kuskokwim Delta berry harvesting location maps

Participatory mapping is a general term applied to activities that work with participants to gather and map spatial information to help communities learn, discuss, build consensus, and make decisions about their communities and associated resources (NOAA 2015). Here we used participatory mapping to document the locations of different species of berries and understand any social, ecolo

GFLOW model used to characterize the groundwater resources of the Great Divide Unit of the Chequamegon-Nicolet National Forest, Wisconsin

The model simulates two-dimensional groundwater flow and base flow in streams in the
Great Divide Unit of the Chequamegon-Nicolet National Forest using the analytic element
program GFLOW (Haitjema, 1995). Significant streams and lakes in the model domain
are represented at varying levels of detail as linesink elements fully connected to the
groundwater system. The...
