Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

This repository contains R language source code used to read eight tab-delimited text files of state-level instances of the U.S. Army Corps of Engineers National Inventory of Dams (NID). The text file were generated from spreadsheets, which themselves are column-trimmed versions of spreadsheets that were downloaded from the public interface to the NID. The focus of the repository is on...

Spatially explicit maps of annual forest carbon stocks and tabular estimates of land use/land cover change, LULC transitions, carbon stocks and carbon fluxes for selected regions and geographies. Estimates span the period from 2001-2020. Scenarios included are defined with a unique numerical identifier. scn160 = Full Simulation (Land use and Climate Effects) scn155 = Climate Effects only...
GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.2.0 GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.2.0
GSFLOW is a coupled Groundwater and Surface-Water Flow model based on the integration of the U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS; Markstrom and others, 2015) and the U.S. Geological Survey Modular Groundwater Flow Model (MODFLOW-2005, Harbaugh, 2005; MODFLOW-NWT, Niswonger and others, 2011). In addition to the basic PRMS and MODFLOW simulation methods...
Geochemical data supporting analysis of fate and transport of nitrogen in the near shore groundwater and subterranean estuary near East Falmouth, Massachusetts, 2015 Geochemical data supporting analysis of fate and transport of nitrogen in the near shore groundwater and subterranean estuary near East Falmouth, Massachusetts, 2015
Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River Estuary and the adjacent peninsula that was densely populated with residences having septic systems and legacy cesspool inputs of inorganic...
R scripts and results of estimated water use associated with continuous oil and gas development, Permian Basin, United States, 2010-19 R scripts and results of estimated water use associated with continuous oil and gas development, Permian Basin, United States, 2010-19
For more than 100 years, the Permian Basin has been an important source of oil and gas produced from conventional reservoirs; directional drilling combined with hydraulic fracturing has greatly increased production in the past 10 years to the extent that the Permian Basin is becoming one of the world's largest continuous oil and gas (COG) producing fields. These recent techniques extract...
Unit hydrographs of evolving urban watersheds across the United States Unit hydrographs of evolving urban watersheds across the United States
The dataset contains the land cover, climate (precipitation and air temperature), unit hydrograph and its characteristics (peak and time to peak), and study watershed boundaries. These data were applied to investigate the impacts of changes in land cover and climate on stormflow of evolving six urban watersheds, representing six different hydroclimate of the conterminous United States...

This Data Release contains various types of hydrologic and geologic data from the Upper Rio Grande Focus Area Study from 1921-2017, including groundwater-level measurement data compiled and synthesized from various sources, water-level altitude and water-level change maps developed from the water-level measurement data every 5 years from 1980-2015, and the horizontal extent of 13...
USGS monthly water balance model inputs and outputs for the conterminous United States, 1895-2020, based on ClimGrid data USGS monthly water balance model inputs and outputs for the conterminous United States, 1895-2020, based on ClimGrid data
This NetCDF represents the monthly inputs and outputs from a United States Geological Survey water-balance model (McCabe and Wolock, 2011) for the conterminous United States for the period 1895-01-01 to 2020-12-31. The source data used to run the water balance model is based on the National Oceanic and Atmospheric Administration's(NOAA, 2020) ClimGrid data for precipitation and...
Trevisan, A.R., Paizis, N.C., 2021, MODFLOW-NWT model used for the simulation of the Cimarron River Alluvial Aquifer in the Pawnee Nation Jurisdictional Area in Payne County, OK, 2016-17 Trevisan, A.R., Paizis, N.C., 2021, MODFLOW-NWT model used for the simulation of the Cimarron River Alluvial Aquifer in the Pawnee Nation Jurisdictional Area in Payne County, OK, 2016-17
A three-dimensional, finite-difference MODFLOW 2005 groundwater model using the Newton formulation solver (MODFLOW-NWT) was created for the Cimarron River alluvial aquifer in Payne County, north-central Oklahoma to assess the effects of current groundwater withdrawal rates with respect to current and future groundwater availability and on base flow in the Cimarron River. To better...
